Good bacteria?

2010-04-24T08:21:00.000-07:00

What Can you tell me about acidophilus? I heard it can be good for your stomach but what kind of symptoms does it treat? My husband has been having bouts of nausea for no apparent reason and also gas pains. Would this help him? Thank you.

Good bacteria?
There are more than 400 different species of bacteria in the human digestive tract. The most important of these are Lactobacillus acidophilus and Bifidobacterium bifidum. They are called probiotics, the opposite of antibiotics, because they aid in creating a healthy balance of microflora in the gut.

The primary use of probiotics is to restore the normal flora in the intestines that often occurs because of poor diet or the use of antibiotics. They do this first by competing with other organisms for nutrients. They secrete lactic acid and acetic acid that decrease the pH of the vagina and intestines, making the environment less favorable for the pathogenic bacteria to thrive. Antibiotics can alter the bacteria in the gastrointestinal tract, decreasing the numbers of healthy bacteria and causing diarrhea. Probiotics, taken during or after antibiotic therapy, can reduce or prevent this effect.

Probiotics produce certain antimicrobial compounds that kill some of the undesirable pathogens in the intestines, including yeasts, virii and bacteria. The associated decrease in the production of potentially cancer-causing toxins by the unfavorable microorganisms may help decrease the incidence of colon cancer. Probiotics also make certain vitamins needed by the body including folic acid, vitamin B6, niacin and vitamin K.

When large doses of probiotics are first taken, mild gastrointestinal symptoms may occur and flu-like symptoms may also occur within 3 days. Low counts of Lactobacillus and Bifidobacterium, with an increase in less desirable bacteria in the intestines can cause gas, diarrhea, constipation, mucosal irritation and contribute to the development of allergies.

As the number of undesirable bacteria increases, the absorption of certain nutrients, including the B-vitamins, decreases, leading to the possibility of deficiencies. Symptoms of toxicity from taking probiotics are rare.

If supplementation is needed, start by taking at least 1-10 billion viable L. acidophilus or B. bifidum cells daily divided into 3 or 4 doses.

Take them on an empty stomach or at least 30-60 minutes before eating. Take 15-20 billion viable organisms daily to prevent diarrhea from antibiotic therapy.

Generally you should use products that contain a mixture of live organisms and have an expiration date on the label. Extreme heat or freezing can kill the live cells. Food sources of probiotics include yogurt and milk with live cultures.
Reply:Acidophilus works in the colon, not in the stomach. The bacteria is necessary to process food after it leaves the stomach and enters the colon.

Your husband can try chewing some anise seed - it helps with gas.

Make sure he is regular. At least two bowel movements a day. If that doesn't happen, eat more fiber and drink more water.

Bouts with nausea can be caused by a multitude of problems, so if this continues, he probably should see a doctor.
Reply:Lactobacilus acidophillus.....that is yogurt. Doesn't hurt to eat some and see :)

(background info......that bacteria also breaks down the lactose sugar, which is related to lactose intolerrance. So people who are lactose intollerrant can eat Yogurt just fine. If your husband is hispanic or asian or black or any mix of those, go ahead and stop cheese/milk for a while and see how that works.)

Good Luck
Reply:ginger root may help him as well.
Reply:Acidophilus is good bacteria which is in your stomach and small and large intestines normally. It can help your body digest food better and regulate your system. It is great for conditions like yeast infections and Irritable bowel syndrome (IBS). Symptoms of IBS can be gas, pressure, abdominal pain, nausea, diarrhea, constipation, and Mucus in the stool. A lot of the pain of gas is related to yeast and digestive problems that can be helped by good bacteria.

I do think that a probiotic of some kind would help him...yogurt or a suppliment. I do think though that these symptoms should be brought to the attention of a doctor in case more is going on. Probiotics may help even if he has something more serious. Better safe than sorry although likely the probiotic will be enough as long as it is strong enough!

Reply:Try Algo Clay, 100% natural. You can find it at www.clayforlife.com

It works great for any stomach problems and regulates the entire digestive system.
Reply:Most definatly it would help. just go to your local nature store and ask for it. It's also great to give children after they have had a round of antibiotics. Your husband may also want to try Marshmallow Pepsin (From Nature Sunshine Products) Great for an upset stomach
Reply:I use it to treat cold sores sometimes. If I can't find Lactinex, I will start taking acidophilus at the first tingle and sometimes the cold sore never finishes developing. Either that or it heals fast.

I have also taken it when I was on an antibiotic just as a preventative measure.

I have never taken it for stomach problems.

Do bacteria actually eat agar?

2010-04-24T08:20:00.001-07:00

Yes, when agar contains all the nutrients the cells need to thrive, it can easily be used as an energy source. Nutrient agar plates are used to grow bacteria in laboratories.

Do bacteria actually eat agar?
It is a polysaccharide; why not.
Reply:No the eat the nutrient that is added to it
Reply:no, but i heard that microorganisms tat live in car gas can run an engine by eating sugar or something with high concentration
Reply:agar is just a medium. when the bacteria grow and multiply from the nutrients in the agar. they will slowly die when all the nutrients are gone and only agar is left. this is exhibited in laboratory culture medium. if you want to keep a specific bacterial sample. you have to keep transfering to new medium. there are really dangerous bactria in regulated laboratories for purposes of researches.

Why bacteria, the very simple organism, can live in the extreme environment?

2010-04-24T08:20:00.000-07:00

the animals which are evolved for long long time can't do.

Why bacteria, the very simple organism, can live in the extreme environment?
evolution
Reply:they reproduce quickly so they evolve quickly which makes them adaptable. If a few survive in a harsh environment and there is a source of food they will soon multiply and colonise a new niche!
Reply:Because they are so simple, they have less to go wrong with them. Same way a yo-yo has less problems then say, a computer. Have fun!
Reply:bcuz it can fit in to any enviroment
Reply:Recent research has shown that bacteria have an extraordinary resistance even to the most severe and harsh conditions. Particularly, the bacteria known as spores are resistant to extremely high temperatures and drought for extended periods. This is why it is difficult to destroy certain microbes.
Reply:Adaptation. Look at pyrococcus, living at temperatures that would fry us...

Their membranes are adapted to not be destroyed by heat among other things. Biggest issue is DNA degradation by heat; since DNA cannot be adapted, they developed dna polymerases that replicate dna so fast it's not funny, thus dna damage is minimal.
Reply:as an appendix to the guy above me, the upper limit is actually predicted to be the temperature at which ATP breaksdown.

The answer to your question is to do with the rate of replication. Because there is only one cell, with e.coli, it divides in 20min....so in a day, there are literally millions of bacteria, each of which could be slightly different, adapted to live in other conditions.

Higher life forms are more evovled, but evolved to different enviromental conditions.

Can bacteria or insects live in an alkaline or alkaloid environment?

2010-04-24T08:19:00.002-07:00

llinois groundwater scientists have found microbial communities thriving in the slag dumps of the Lake Calumet region of southeast Chicago where the water can reach extraordinary alkalinity of pH 12.8. That's comparable to caustic soda and floor strippers -- far beyond known naturally occurring alkaline environments.

The closest known relatives of some of the microbes are in South Africa, Greenland and the alkaline waters of Mono Lake, California.

there was a unmanned moon mission a couple of years before the manned, I'm not sure of the timespan. I think someone else can build on it.but anyway the astronauts went to this vehicle and pulled the camera lens, took it back, swabbed it and found that some one contaminated the interior with a sneeze or something. They fed it and sure enouph bacteria sprang up ready to rock. Gives you the spooks don't it

Will bacteria or virus be able to survive in mars?

Reply:according to many scientists, bacteria and viruses are probably not able to be sustainable on the martian surface, but thoughts are that since mars once supported life a question is still unanswered whether underneath the surface of mars bacteria or traces of life may have survived. to many it is a goal to find out
Reply:Yes, why not...bacterial and viruses can grow at any timperature...the kind of bacteria found on mars would be definately differnent from earth.
Reply:They found evidence of bacteria on Mars in 1997 I guess that answers that.
Reply:Yes the can . there are types of microbes that do not need oxygen but use So2 and other gasses for anaerobic energy . these types of microorganism can be sent to a planet and start altering ts atmosphere . in a period of time the atmosphere may be able to sustain other forms of organisms like algae which can be sent later in the process .on the long term the plant can be inhabited
Reply:ya viruses might survive on mars and i don know about bacteria
Reply:they can because when the earth was young and just millions of years old, earth was like mars and viruses and bacteria lived through it.

Can bacteria have sexual reproduction, what is the process use for this?

2010-04-24T08:18:00.003-07:00

Bacteria do divide and reproduce by asexual binary fission, but certain bacteria use a process called budding that involves a growth enlarging to cell size and then budding off. Keep in mind that some bacteria also exchange genetic information with a part of prokaryotic anatomy called the Pili (or "sex pili") which looks like a flagella, but i think it is shorter.

Can bacteria have sexual reproduction, what is the process use for this?
No, bacteria usually reproduce through asexual reproduction, by using the process of binary fission.
Reply:A little thing called mitosis. (Or does that only work with eukaryotes... I don't remember.).
Reply:'Sexual reproduction' in bacteria means the swapping of genes between two individuals. Some bacteria do this. For example, E. Coli that contain the 'F-plasmid' can form a structure called a pilus that connects with another E. Coli that lacks the F-plasmid, and genes are transfered. This is called conjugation, it is a type of sex, but it isn't very fun.

Dermal bacteria in urine take 2 weeks to raise pH to 9.2 by urea hydrolysis, why so long?

2010-04-24T08:18:00.002-07:00

In our urine storage studies, it normally takes between 5 days and 3 week to see urea hydrolysis raise the pH to 9.2. Since we measure 10^6cfu/mL after only 2 days, why don't we see urea hydrolysis sooner? Are the bugs just eating organics without synthesizing urease? Our typical initial urea concentration is 7 g-ureaN/L and about 250 mg-TAN/L. I've also noted that we get urea hydrolysis quicker if the samples are subject to a cold temperature daily cycle. Our D.O. measures %26lt;0.1 mg/L after only one day of storage. Is urease synthesis a slow process? What is limiting the rate of urease production? Could it be nickel?

Dermal bacteria in urine take 2 weeks to raise pH to 9.2 by urea hydrolysis, why so long?
urease is a protein. Urease is found in bacteria, yeast and several higher plants.

Characteristics:

Active site metal: nickel(II)

Molecular weight: 480 kDa or 545 kDa for Jack Bean Urease (calculated mass from the amino acid sequence).

Optimum pH: 7.4

Optimum Temperature: 60 degrees Celsius

Enzymatic specificity: urea and hydroxyurea

Inhibitors: heavy metals

Reply:yes bacteria helps to break down the organic matter.
Reply:yes
Reply:yes indeed it is. integral
Reply:yes, All package treatment plants use the aerobic (with oxygen) digestion process to treat sewage. In this process, oxygen-using bacteria attack and break down the organic portions of the sewage into simpler inorganic compounds. Aerobic treatment is preferred because it is rapid and relatively odor free. It also provides greater solids reduction.
Reply:absoulely YES!!!
Reply:yes
Reply:yes they are

there is a stage in sevage treatment in which the the aerobic bacteria oxidise the substances excreted like the carbohaydrates, lipids and proteins which are naturally present in human excreta

even the effluent treatment plants of the industries like dairy industry employ these bacteria.

Could bacteria survive on the moon?

2010-04-24T08:18:00.000-07:00

Bacteria can survive on the moon. This was demonstrated by the Apollo 12 mission, which brought back parts of the Surveyor 3 probe. More details can be had below.

Bacterial spores are extremely durable and are difficult to kill. The ones on Surveyor (contaminated with Earth bacteria before launch) survived for 3 years in hard vacuum and enormous temperature swings.

Could bacteria survive on the moon?
somebacterias can survive in extreme conditions. maybe someday a special bacteria will be found that can live in the space.

these bacterias will have the ability to talurate high pressures and tempretures. these kind will be non-aerobic bacterias. Report It

Reply:maybe a bacteria in the closteridium or bacillus family will have this abillity. Report It

Reply:No - there is no atmosphere.
Reply:-on- the moon, most likely not. The zero suck of the void would rip them apart. -in- the moon or a capsule on the moon... maybe, if conditions are right.
Reply:Well, thats a somewhat complicated answer. To begin with bacteria require two things water and an atomosphere. And the moon has neither. Now, when I say atomosphere I mean that there needs to be a layer of gases that surround the moon; these gases are essential in building the materials needed for bacteria to thrive, survive, and replicate. Recently, however, we have seen that comets and asteriods do contain traces of bacteria, but no living bacteria only traces of its existence.
Reply:NO.... I don't think so

but I wouldn't be suprised. life is a wonderous thing.

bacteria are known to make their own atmosphere. and if there is some water found. maybe
Reply:There are anaerobic bacteria which die as soon as they come in contact with air. Probably they may survive in moon.
Reply:From the limited perspective of gravity, etc., some bacteria would hardly be bothered. More importantly, the surface of the moon would appear unable to provide them with the nutrients that they require to survive, and the constant pounding of cosmic rays, not being stopped by a functional atmosphere, would make things very difficult. Specific bacteria are remarkably capable of living in hostile environments such as deep ocean vents, hot sulfur springs, etc. but the moon would seem to be a near impossible place for them to reside.
Reply:what do you mean bacteria?there are thousand kinds of them some of them can survive on the moon and some of them can't.

you know why? those witch can stay alive have a nonaerobic system of breathing.
Reply:as others are saying no, i think its a yes, if we can go out on the moon and get a cut and get that infected there could possiably be bacteria, there is bacteria everywhere, even though its on another planet.

If bacteria are prokaryotic...?

2010-04-24T08:17:00.002-07:00

...how do they perform cellular respiration without mitochondria?

If bacteria are prokaryotic...?
I believe the enzymes necessary for aerobic respiration are in the cytosol and they make use of the plasma membrane to create the gradients (instead of the inner mitochonrial space).
Reply:I agree with Rick P.
Reply:because the enzyme which find in mitochondria and make the cellular respiration they are found in the plasma membrane of bacteria instead of mitochondria and do the same job like ( cytochrome oxidase %26amp; cytochrome c reductase) so bacteria don't need to mitochondria
Reply:They are essentially mitochondria themselves.. That's the basis of the endosymbiotic theory; a prokaryote was taken into a eukaryotic cell and a symbiotic relationship formed, the prokaryote producing energy for the cell while getting nutrients (and protection from the environment).

Also, cellular respiration occurs in the membrane, fermentation occurs in the cytosol.

Can bacteria or a virus pass through breastmilk?

2010-04-24T08:15:00.002-07:00

Say I had a stomach virus or a bacterial infection of some sort, could I pass it on?

Can bacteria or a virus pass through breastmilk?
Depends on the type of virus. HIV can be spread through breastmilk, so can hepatitis. The common cold is NOT spread that way, and stomach viruses are generally spread through fecal contact or contact with the vomit (gross, huh?), so no problem there either!

Breastfed babies RARELY get sick because mom is sick... because even if you pass the virus to the baby you are also passing antibodies through nursing, so the baby gets better even more quickly than you do (if he or she gets sick at all!)

Are bacteria that live in “typical” environments like on your hands, in foods, and in soil.?

2010-04-24T08:15:00.001-07:00

Bacteria is everywhere. It's different types and some are good and some are bad. You even have bacteria that are good in your stomach. Some bacteris, like E COLI in your intestines, is okay when it's there but can make you sick if it gets on to your hands and you transfer it to other people. Some bacteria just infect plants! I think Bacteria is fascinating, but oh so deadly.

Are bacteria that live in “typical” environments like on your hands, in foods, and in soil.?
Yes that is why people are asked to wash their hands. Also bacteria lives on the food you eat that causes your breath to stink its pretty much everywhere our bodies can defend over simple food Bacteria
Reply:Bacteria live in many environments. Different species live in different places. For example a bacteria called Streptococcus epidermidis lives on skin and helps protect the skin from colonization by other harmful bacteria (disease-causing species)- so one has nice and healthy skin. Other bacteria such as Thermus aquaticus live in boiling springs -such as those of Yellowstone hot springs. Bacteria can be fussy, so not all species can live just anywhere. Those growing on the skin cannot grow in the hot springs for example and so on...
Reply:yes. there are bacteria on practically any part of of your body inside and out!!

The smell of soil is that of bacteria ( when you grow it on agar you can get that "earthy" smell...very wierd.

Just to point out that only 5% of bacteria are consdiered pathogenic...that leaves a massive 95% that are neutral or beneficial bactieria....the ones on our skin help to defend off bacteria and why I am personally against antibacterial body soaps as you need the bacteria there to help ward off the nasties....why kill off your defenders!!???

Are bacteria and viruses "extra terrestrial"?..?
No they are not ET. You will have to first figure out 'Where the world came from?' However I do know that they have some on the International Space Station, do not know what they are.

which one is the most dangerous, and which one is the least dangerous out of these three bacterias: coccus, bacillus, spirillum

Which bacteria is more dangerous? coccus, bacillus or spirillum?
what you have described is a shape for a group of bacteria instead of species capable of causing a disease, but lets see a few of each:

coccus- Streptococcus pyogenes caused rheumatic fever and most strep throat infections

Staphlococcus aureus- normally a harmless occupant of a persons skin is a major cause of infections in burn units sand other hospital based infections

Neiseria gonnorea- causes gonnorea

Bacillus

Bacillus anthrasis- causes anthrax a potentially fatal disease

Clostridium botulium- causes botulism in incorrectly canned food

Clostridium tetani- causes tetanus or lockjaw

Clostridium perfringes- causes gas gangrene

Spirillium

Most spirillium are harmless...with one notable exception:

Treponemia palladin- causes syphillus

The most dangerous as measured by number of diseases would easily be bacillus. The least would be spirillium.
Reply:look in your textbook
Reply:I dont think one is more dangerous than the other.

I thought it just depended on what kind of it.

Like strepococcus or something like that.
Reply:depends on what the bacteria is

anthrax are rod shaped bacillus

stapherius epidermus causes acne (more of a nuecince than dangerous)

stapheriuscoccus casues dangerous staph infections

i dunno very many sparilled shaped spirillum off ahnd - but undoubtily some r very dangerous

also, it depends on if its optistic bacterium - some skin (soemthing epiddermus) bacertia will only attack the unlucky hosts if the host is down - these usually are in hospitals where hosts (humans) immune systems are most vulnerable

In bacteria, what is a psuedospamodulating leaflet?

2010-04-24T08:13:00.003-07:00

It refrences with Legionella. (If you don't know, don't answer. This word is weird enough on its own.)

In bacteria, what is a psuedospamodulating leaflet?
Legionella pneumophila is a thin, pleomorphic, flagellated Gram-negative bacterium of the genus Legionella. L. pneumophila is the primary human pathogen in this group and is the causative agent of legionellosis or Legionnaires' disease.

While L. pneumophila is categorized as a Gram-negative organism, it stains poorly due to its unique lipopolysaccharide-content in the outer psuedospamodulating leaflet of the outer cell membrane. On the side-chains of the cell wall are carried the bases for the somatic antigen specificity of these organisms. The chemical composition of these side chains both with respect to components as well as arrangement of the different sugars determines the nature of the somatic or O-antigen determinants, which are important means of serologically classifying many Gram-negative bacteria. At least 35 different serovars of L. pneumophila have been described as well as several other species being subdivided into a number of serovars.

Is bacteria classified by shape, oxygen requirement, reaction to stains and no present in a colony?

2010-04-24T08:13:00.000-07:00

not sure what you're asking here, but yes to all of the above.

-shape can be round (cocci) or stick (bacillus)

-arrangement is also a factor, as they can be grouped as spheres, pairs or chains

-oxygen req. can be aerobic or anaerobic or a mixture/both depending on the surrounding environment

-the bacteria can be gram positive or gram negative (there are many other staining techniques as well)

-"no present in a colony" ??? do you mean whether they form a colony or stay apart as individuals??

Is bacteria classified by shape, oxygen requirement, reaction to stains and no present in a colony?
Pretty sure thats all of them. I think group may have something to do with it too -- like if they're arranged in a cube, or a pyramid, etc.
Reply:Bacteria is plural for bacterium (latin)

So, you must say "Are bacteria classified by shape, ox. requirement etc...."

Sorry, I could not stop myself.....
Reply:Yes!! If you think in terms of a journey, the purpose of which is to

put the correct name to the bacteria then what you've said would

certainly put you on the right road but in most cases you would need to build on the info and go a bit further to actually establish the true

identity of the unknown bacteria. Starting with gram staining reaction, a positive purple would send you hunting North whereas a

negative red would send you hunting South. Under the microscope,

cocci would veer you off towards the West and rods towards the

East. So find gram pos cocci, look NW and zero-in for ID!!

Some of them primarily cause respiratory problems (Hemophilus influenzae, Klebsiella pneumoniae, Legionella pneumophila, Pseudomonas aeruginosa), primarily urinary problems (Escherichia coli, Proteus mirabilis, Enterobacter cloacae, Serratia marcescens), and primarily gastrointestinal problems (Helicobacter pylori, Salmonella enteritidis, Salmonella typhi).

Nosocomial gram negative bacteria include Acinetobacter baumanii, which cause bacteremia, secondary meningitis, and ventilator-associated pneumonia in intensive care units of hospital establishments.

Which bacteria are most frequently associated with gram negative sepsis?
Not a definite answer, but [1] below says from a small population: "The most common isolates were Escherichia coli, Staphylococcus aureus, and Streptococcus pneumoniae." E. coli is gram negative while the other two are both gram positive [2][3][4], so I suspect that is the answer.

Ok, I just verified it. From [5]: "E. coli is by far the most common gram-negative bacterium causing sepsis. " So I'm pretty confident that is the answer.

(By the way, if you are looking for a list instead of a single type, [5] also has this: "Klebsiella, Proteus, Enterobacter, Serratia, and E. coli, are all common gram-negative bacteria causing septicemia.")
Reply:Pulmonary intravascular macrophages: their contribution to the mononuclear phagocyte system in 13 species and is most frequently associated with bacterial peptidoglycan-associated lipoprotein and organ dysfunction. Now if I can only pronounce all that!
Reply:It depends on the type of septis. Usually you're looking at ecoli. It's pretty easy to get.

If it is sepis from an animal bite, however, it's like 90% pasteurella.

Got pasteurella from a neighbor's cat I tried to help her medicate. In 8 hours I went from sore to unable to move my arm. And this was after I cleaned the bite properly and everything. Not fun, but not a one of the biology students I have taught thinks animal bites are no big deal now.

Can Bacteria decompose metal rust?

2010-04-24T08:12:00.000-07:00

Yes. There are several genera of microorganisms that are capable of reducing ferric iron to its ferrous state.

Most are extremeophiles - organisms that live in harsh conditions such as high heat or extreme pH. The method is through production of iron reductase enzymes.

If you're really interested, follow the link below and do a search for 'iron oxide'.

Differentiate bacteria and virus.?

2010-04-24T08:11:00.002-07:00

Viruses are the most elementary of organisms consisting of only an RNA strand for chromosomal structure and a protien capsule enveloping. The nature and function of the virus lies in its RNA. In fact, viruses can be deactivated and preserved in the form of harmless crystals. They are actually dead in nature and function in this form. This is how viruses border on the living and nonliving forms. Bacteria are much more advanced organisms having a DNA (double stranded) with more complex physiology and function.

Differentiate bacteria and virus.?
A bacteria is a much larger organism than a virus. It takes an electron microscope to view a virus.
Reply:virus is entirely harmful .but bacteria is both useful and harmful.virus is much smaller than bacteria
Reply:Bacteria can live on their own , virus have to invade a host in order to replicate .

Virus is much smaller than bacteria. Infact Virus is so small, their complete structure can not be seen clearly even with the most advanced microscope ( electron ) . Bacteria is way bigger. Some virus like HIV virus are able to mutate quickly and unpredictably , and most virus are harmful . Bacteria can be harmful ( E.coli , Salmonella ), while others can be used in food industry ( to make dairy products like yogurt, cheese ..)

When a virus replicate , their " daughter " is often the same size as the parents. when bacteria replicate, their daughters are often smaller size . Bacteria replicating machenism is like cell division.

Virus has no cell wall, no cellular structure or cell membrane, it only has DNA or RNA ( coiled string of nucleic acide ) enclosed in a protein capsule. Bacteria are often unicellular organisms has cell wall , cell membrane , and internal structures like mitochondria , golgi apparatus...bacteria can live independently and replicate on their own .
Reply:Bacteria are cellular organisms, but viruses do not have cells, or even parts of cells. Viruses are just DNA or RNA protected in a protein shell. Bacteria have the characteristics of life, they need food, they can multiply, etc. Viruses do not need food. They cannot multiply on their own. They are like parasites in that they require living cells in order to reproduce. They hijack cells and use their DNA or RNA to force the cells to make more viruses. Some people consider viruses to be alive, some people say they are not alive. Just because they can reproduce does not make them alive. There are molecules which can mindlessly create copies of themselves if given the right conditions. Maybe this is how life started, we don't know.

Can bacteria mutate? how?

2010-04-24T08:10:00.001-07:00

Yes, when there are several different types living together somewhere, one kind usually does better. And they have plasmids containing genertic materials that help them cope with their surroundings. Often they trade these with each other, sometimes even species to species rather than just within species.

They also mutate in response to chemicals and radiation. Maybe all die except for the one mutating bacterium, but then it grows. This happens when people abuse antibiotic treatments or do not complete them. A big example is NYC drug addicts with HIV and TB. It's hard enough to kill TB if they complete their treatment, but when they stop after only one or two weeks, the TB recovers from the antibiotics used and develops resistance to them, producing MDRTB (multiply drug resistant TB) or if it is already MDRTB, it gets even more resistance to the latest ones for MDRTB. Also a big problem in Russian prisons and drug abusers.

Reply:Not as fast as viruses, but they do mutate. In fact, many are now resistant to antibiotics becasue of mutation. The non-resistant ones die off, leaving the resistant ones to prosper. Natural selection in a nutshell.
Reply:how i understand bacteria mutatin is mutation as in resistance to antibiotics. bacteria like all cells have organelles. one of which is the endoplasmic reticulum. there r two types of these namely smooth and rough ER. the sER is involved in drug detoxification and synthesis so when there is bacteria lets say within the stomach and we take drugs for this bacteria to kill it. it might work the first time but later on the bacterias sER will begin to adapt to the drug taken and soon it will b immune to the drug. that in itself is a mutation of the original bacteria to suit its environment in order to survive.

What bacteria can make its own food?
Cyanobacteria, which are blue-green in color, are a form of bacteria which can make their own food through the process of photosynthesis. And because they are the only group of organisms that are able to reduce nitrogen and carbon in aerobic conditions, they are important in aerating the soil, which is necessary for the growth of plants. Another term for cyanobacteria is blue-green algae.

Do bacteria develop resistance on disinfectants like they do in antibiotics?how?

2010-04-24T08:09:00.000-07:00

Generally speaking, no. They do NOT develop any type of resistance to disinfectants. Resistance to antibiotics has a specific genetic basis, and usually only requires one genetic change.

Disinfectants are much more broad in their attack on bacteria, such as denaturing the outer membrane, or inactivating all proteins, etc. A single, or even several, genetic changes are not enough to make a bacterium resistant, they would need wholesale evolutionary changes to their anatomy, and that takes millions of years.

So, no, they don't become resistant.

Reply:old cosmetics, especially shared old cosmetics.
Reply:Bacteria, often in combination with yeasts and molds, are used in the preparation of fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, and yogurt.

"Friendly bacteria" is a term used to refer to those bacteria that offer some benefit to human hosts, such as Lactobacillus species, which convert milk protein to lactic acid in the gut. The presence of such bacterial colonies also inhibits the growth of potentially pathogenic bacteria (usually through competitive exclusion). Other bacteria that are helpful inside the body are many strains of E. coli, which are harmless in healthy individuals and provide Vitamin K.

Bacteria are both harmful and useful to the environment and animals, including humans. The role of bacteria in disease and infection is important. Some bacteria act as pathogens and cause tetanus, typhoid fever, pneumonia, syphilis, cholera, food-borne illness, leprosy, and tuberculosis(TB). Sepsis, a systemic infectious syndrome characterized by shock and massive vasodilation, or localized infection, can be caused by bacteria such as Streptococcus, Staphylococcus, or many gram-negative bacteria. Some bacterial infections can spread throughout the host's body and become systemic.

Some bacteria have became drug resistant and the same is a posing a threat to old patients and babies especially staying in ICU in hospitals.

i think u mean can an animal get infected by a bacteria infection then yes they can.

antibacteria agents can help fight bacterial diseases,

ill tell you how!

u know what peptidoglycans are ?? they are a component of the cell wall the bacteria has, penicillin binds to a pinicillin binding protein in the bacteria and this will prevent the growth of cell wall, this will lead the bacteria to release enzymes such as lysis which will destroy it and this is all due to fragile celll wall,

Viruses has No enzymes = no metabolism = resistance to true antibiotics

Most viruses are:

very susceptible to oxidising agents and radiation damage

resistant to quaternary ammonium and other biocides

Viruses with a lipid envelope are damaged by organic solvents and detergents

Many viruses are inactivated by;

extremes of pH

drying

moderate heating, e.g. 50°C for 30 minutes,

but survive freezing well.

My question is has anyone used Metronidazole before has it helped .?for giardia

Puppy bacteria help?
I'm pretty sure that metronidazole is the only medication that is used to treat Giardia. It's an antibiotic that also helps reduce inflammation in the colon. It is frequently prescribed for dogs with diarrhea, but for giardia a larger dose for a longer amount of time is frequently prescribed.

It is also sometimes called "Flagyl" (the brand name). Try googling it and see what you come up with.

ADD: It is very effective for the treatment of giardia. Reinfection occurs when your dog contracts the parasite from contaminated water sources, IE drinking water out of lakes or ponds that fecal matter from infected animals runs into. You can also research what giardia is and how it is passed on the Center For Disease Control government website, http://www.cdc.gov

If bacteria only reproduce asexually, how can they transfer genes?
it is called lateral or horizontal gene tranfer. Basically two bacteria join, exchange genetic material, separate. Result two bacteria each of which has now different genetic material than they had before having sex. Can only work in unicellular organisms.

Look up more on the web or in your text book
Reply:Um....when they REPRODUCE they create a complete COPY of themselves....GENETICALLY! DUH!
Reply:They don't just reproduce asexually. They do pair up and swap genes as well. It's more of a merging than sex, as such.
Reply:i no that i just dunno how to explain it wish i could be of more help but id say ud find out moer about it if you googled it bit by bit
Reply:It's called conjunction. One bacteria uses a "sex pilus" to inject some DNA into another bacteria, thus they transfer genes. (and as someone else pointed out, that's called horizontal gene transfer)

There is another way that genes can get to one bacterium to another, and that's transduction. That is where a bacteria gets DNA from a bacteriophage, a virus that can pick up DNA from one cell and give it to another.

Is bacteria made of tissues, organs and/or organ systems?

2009-11-20T04:05:00.002-08:00

Bacteria are not at all similar to cellular organisms.

They have no tissue or organs, since those are composed of cells.

Bacteria are much smaller and simpler than cells, although their DNA is surprisingly complex.

Bacteria are actually quite fascinating and they have many interesting facets that are not found at all in cellular organisms. The flagellum, for example, in some varieties is powered by a tiny microscopic motor that is powered by acid.

The world of bacteria is only now beginning to be opened up through the relatively young science of microbiology. I would encourage to read more about them if you think you would find it interesting.

After seeing the other comments, I felt compelled to add that bacteria are NOT cells.

He told the Jews not to eat shellfish ... did you think He did it because He hates lobsters? lol It was because (as we all know now) if you don't cook it live, it's no good.

He told the Jews not to eat pork ... did you think it was because He didn't want them to be called pigs? No, it was because pigs back then were not grain fed like now, they were scavengers who literally ate excrement if allowed. Pigs don't have the stomachs like a cow to process that, so it goes into their fat and meat. Hence, full of bacteria that can make you sick.

Reply:No, Instead the bible refers to demons. Biblical medical practices mostly consist of sacrificing animals or birds. You don't see too many Christians sacrificing pidgeons any more though, even though the bible clearly tells them to.
Reply:The bible left a lot of things out. God probably figured it was already long enough...

Also, although the writers knew what to say through God, he put it in human hands so the language could be understood. That's why the old testament is filled with long and really weird sounding names and measurements, and why bats are called birds, because that's what everyone called them back then.

God doesn't bring up a lot of things; the platypus, black people (though they come up in the new testament), coconuts, Albinos. In fact, God intentionally left out the biggest detail of all, when Jesus would return. In case you haven't noticed, every generation has predicted he's about to come and his reign would begin, and they were all wrong, because Jesus left us hanging on purpose.

So if God would leave that out, is it so surprising he wouldn't bother telling the writers about little invisible animals that make you sick?

Note: Bacteria are not part of the animal kingdom as defined today, but taxonomy was very different 6 thousand years ago, they would have almost definitely been referred to as animals back then.

I don't think they took up much room, but my God it must have been difficult finding them in the first place!!!

cf Noah was a bloody fool- he had the chance to rid the world of every plague bacillus, bloody housefly and sea gull, but instead made sure they were preserved in his Ark. What a tosser!

Good bacteria cultures in yogurt help yeast infections, doesnt sugar in the yogurt have a counter effect?

2009-11-20T04:04:00.000-08:00

I've heard that sugar feeds yeast infections?

So is eating yogurt a good or bad idea to help prevent yeast infections?

Good bacteria cultures in yogurt help yeast infections, doesnt sugar in the yogurt have a counter effect?
You can always purchase sugar free yogurt.

You can also just count the carbs as part of your meal and cover for it.

BTW- no one with diabetes should eat raw milk.We catch infections easier than others who do not have compromised immune systems.

An infection will raise our sugars and thus be harder to control.

No raw honey either.

It is much safer for us to eat foods that have been pasteurized.
Reply:I'm not convinced that the sugar in yogurt feeds the yeast infections, but it surely does play havoc with my glucose readings!!!
Reply:When I eat yogurt I look for plain w/ live cultures ( raw milk kind if available). You do need to pay attention to the sugar content or it will defeat the purpose. Plain is best with fresh fruit and something like wheat germ for crunch.

Check out these links for info on the benefits of raw milk:

http://www.realmilk.com/healthbenefits.h...

http://www.rawmilk.org/

Good luck

Edit: I am not a doctor, I'm only speaking from personal experience.

I began drink raw/unpasturized milk and eating raw milk yogurt and cheese when I began working for a fomager in a cheee shop. I noticed that my blood readings dropped from 175 fasting in the am to 115-120. I developed no infections, and have always been prone to them, and I had no indigestion which I normally get when drinking milk.

The ability to purchase unpasturized products is becoming easier and many alternative doctors, natropaths %26amp; homopaths, will tell you that raw is better.

In europe and other parts of the world, it's common to find these foods and perfectly healthy.

Of course....speak to your doctor first before starting anything. I did and after giving her information on the benefits and saftey factors enforced on farms that are allowed to sell these products, she agreed and has since recommended it to other patients.

I , also, suffer from no yeasts infections when ingesting raw/unpasteruized products...so for me, it works.

Do the research yourself.....maybe it will, maybe it won't be the right thing for you, but atleast check it out.
Reply:You can easily purchase sugar-free yogurt. It is delicious.

Cyano bacteria ,sick of it!?
I was unusual in that I had a cyano bacteria bloom in a tank just 3 months old. Did some research at wetwebmedia and several references to red legged crabs being eaters of that type were discussed so I tried it.

I only bought a couple of them, took a couple of weeks, but the bottom line is that they worked and I have not had a reoccurrence in over a year now. Not saying it is the ultimate answer for you, but it might be a place for you to begin, along with some of the maintenance tips provided by other answerers.

Hope this helps.
Reply:I recommend using about half the recommended dose of Algone. This cleared my tank up in a couple of days.

Generally, I always use lower doses of medication then recommended, so as to not shock my fishies!

Hope this helps you.
Reply:Unfortunately, it is almost impossible to get rid of. I have tried the black out method where you cover the tank so it gets no light at all for 3 days. That works but as you said, it seem to come back. I have heard and read of people using Maracyn (I think) with success but have not tried that myself.

When I had it so bad in my 29 gallon tank, I finally just started over and it never came back. I still have it in my betta tank and will be redoing it soon.

Top-off with Kalkwasser

Regular bulb changes

The Protien skimming, RO/DI water and Maintenance animals worked for me.
Reply:Physically remove as much of the cyano as you can.

If you aren't using already, use RO or RO/DI water.

Increase water flow and circulation to eliminate low flow or 'dead areas' in the tank.

Utilize a macroalgae packed refugium to outcompete the cyano and a protein skimmer.

In bacteria cells, how are proteins made? and what do proteasomes do to break down these proteins?

2009-11-20T04:03:00.000-08:00

Proteins are made just as they are in eukaryotes via the process known as translation. The ribosomes are slightly different (70S in prokaryotes versus 80S in eukaryoties) but they're still made up of rRNA and protein subunits. In eukaryotes, transcription (DNA ---%26gt; RNA) and translation are temporally and spatially separated by the nuclear membrane. In prokaryotes, however, there is no such separation as there is no nuclear membrane. That is transcription and translation can occur at the same time. I'm not sure how protein degradation works in prokaryotes - but i know in eukaryotes, proteins to be degraded are ubquitinated and this targets them for degradation by the proteasome. That's as much as i can offer

i think that if its not open then its okay but i tink the only way that bacterial will form is everytime u take a drink out of it with ur mouth.
Reply:The fact that it's sealed makes all the difference. It's basically sterile. So it should be fine to drink.
Reply:The only way bacterial growth will occur is if the seal is broken and bacteria is introduced (by drinking from the bottle). Even if the seal has been broken, if nothing has had contact with the water in the bottle (lips, fingers), no bacterial growth will occur.
Reply:NO.

Bacteria does not mysteriously appear.

If bacteria was in the bottle (never opened) in the first place then only a slight problem exists (vary rare). It depends on the cell count to be sure of any health concern and for this a lab would be helpful.

Bacteria need a certain temp. (strains vary on this), a food source, and water in order to reproduce. Well there is plenty of water but no food in your water bottle. It is safe. If you have opened it and subjected to these extremes of temp. still your biggest concern is quality not health. Molds would then be your concern. Just a flavor thing.

How to eliminate gram positive bacteria from a mixture of gram-negative bacteria?

2009-11-20T04:02:00.002-08:00

Gram (-) bacteria are resitant to things that Gram positive aren't.

You could eliminate g+ bacteria one of two ways from a culture of both of these types of bacteria.

Gram positive are suceptible to pencilin like antibiotics. Infusing those antibiotics into a culture with both of these bacteria will degrade the cell walls of the gram positive bacteria. They will not affect the gram negative bacteria.

Secondly, gram positive bacteria need specific amino acids and nutrients that gram negative bacteria can synthesize on their own. By creating a specific culture medium, one can kill off the gram positive bacteria.

How to eliminate gram positive bacteria from a mixture of gram-negative bacteria?
any kind of penicillin will do it. Other antibiotics can be effective against gram -, so check before.....

How bacteria makes a person sick?

2009-11-20T04:02:00.000-08:00

Bacteria can make a person sick. But alot of problems come from bacteria that have been destroyed and can't protect us from the harmful bacteria. For instance yeast infections are almost always caused by a lack of the normal flora of bacteria. 60% of all you vitamin K that is used for blood clotting comes from bacteria in your gut. But the three main ways that they cause you to get sick is.

1. The natural flora is destroyed and a "bad" bacteria or yeast can flourish. If this happens then it goes to step 2.

2. The bacteria when it eats nutrients in your blood or body it produces toxins as a byproduct.

3. Or it can actually attack certain cells in your body and can cause harm that way.

Something that is common in older people is that they come in with an infection and the Dr. prescribes a powerful antibiotic called Rocephin. This wipes out the normal flora of the intestines and the person comes down with Clostridium Diff. They then prescribe a more powerful antibiotic called Vancomyacin. This seems to quell the C. Diff. but then they get yeast infections because there is no bacteria to protect them. The bacteria eventually develope a resistant strain called VRE to help combat the void left in the intestine and by this time the person is usually very ill because of the yeast infections and C. Diff. They then develope a Urinary Tract infection by the VRE and develope sepsis and then die.

How bacteria makes a person sick?
Well, there are many ways in which bacteria can make a person sick. But mainly there are two ways in which the operate:

1. Interfering with normal metabolism of the cell

2. Producing toxins which can harm the cell

The bacteria which cause disease are called pathogens and they live in/on our cells where they complete there life cycle.

Is bacteria more harmful than virus?

Some bacteria are beneficial to mankind, whereas I have yet to hear about a useful virsus.

Is bacteria more harmful than virus?
no.. i think virus is ..because there is no cure yet..
Reply:No. It depends on the type of bacteria or virus as to how harmful it is, there are types of both that can kill you and there are also examples of both that don't do much at all. Most bacteria though can be treated with antibiotics, a virus cannot be treated like this.
Reply:Viruses multiply faster than bacteria.They are cellular parasites.They are inert unless they have entered the host cell.

Bacteria are decmoposers and in that sense useful.Many are beneficial in that they fix nitrogen, manufacture vitamins, make milk into curd and so on.You can use bacteria to manufacture useful molecules like insulin by using the techniques of biotechnology.But there are bacteria causing disease like tuberculosis, typhoid etc.
Reply:On the contrary. Viruses or pathigens are more harmful then bacteria. Bacteria remains in our body,in every single corner of the world but yet does hardly any damage; even some of the bacteria are essential for us(Making Curd out of milk, releasing nitrogen from our body,decomposing bio-degradable stuff and helps in making our bonnes strong as well.).these stuff u can not expect from a virus as being a pathogen they tend to mutate and multiply based on the source organism
Reply:It can be, depending on what type of bacteria. On the other hand, it depends on which virus you're talking about. Either can be beneficial, or even deadly.
Reply:depends what kind of bacteria. There are no beneficial viruses, but there are beneficial bacteria, however.
Reply:Bacteria is a kind of organism, which can be defeated by organism. Virus is a genetic mutating agent, which cannot be defeated by organism. So, a virus is more dangerous than bacteria because it changes its genetic code(DNA) every time it invades a cell.
Reply:no virus are much more harmful than the former .viruses have the tendency to make copies of themselves using the DNA of the host and also manipulating it, where as they r non living things outside the host so it is difficult to study them. also there r many hybrids of viruses still unknown to the biologists but they estimate that they would manymore times harmful than the usual as they r the hybrids.the imp. point is they spread from one host to another much faster than bacteria eg: SARS, BIRDFLU etc. also many bacteria r useful like bacillus etc, but till now no virus is considered useful to humanbeings.
Reply:both are equally harmful. For example some species of gram positive and gram negative stephalococci can cause septicemia or septic shop.

Even virus such as hepatic virus can lead to hepatic coma
Reply:the ability of a pathogen (either bacteria or virus) to cause an infection depends on a factor called virulence.

Virulence is either the relative pathogenicity or the relative ability to do damage to the host of an infectious agent. The term is used mainly for viruses, but it can be more generally applied to parasites or bacteria.

Please read more on virulence at Wikipedia

BUT THEIR IS NO BACTERIA KNOWN WHICH CAN KILL VIRUS!.but their r many bacteria WHICH IS USEFULL TO MANKIND!
Reply:The more harmful (to humans) is a bacteria, Clostridium botulinum. It produces botulin toxin, an extraordinarily poisonous substance that is lethal at a dosage of a mere 300pg/kg.

You did not ask about the benefits of viral and bacterial interaction with host organisms, but I will comment on the topic in the possibility that it is of interest. Bacteria, viruses and retroviruses offer benefits, including protection through adaptation of systems to fend of various attacks produced by other viruses, retroviruses and by bacteria.

Is bacteria a producer?

2009-11-20T03:59:00.002-08:00

Yes, most bacteria are producers. In biology, bacteria are called "autotrophs", like plants. The other group are called "heterotrophs", and they are you consumers, like you and me and my cat over here.

Some bacteria, though, are also what you would call "recyclers". I forgot the biological term for recyclers. Some bacteria, on the other hand, feed on other bacteria, so asides from being like plants, they are also like animals, which are heterotrophs.

Is bacteria a producer?
It depends with respect to what prospective u r thinking of, in general they are considered consumers but yes there r some bacteria which can do photosynthesis but they most common ones those help plants fixing N2.
Reply:a producer is an organism that can synthesise its own food. if the said bacteria can synthesise its own food, then yes, it ia a producer.

Cyan & bacteria?

2009-11-20T03:59:00.000-08:00

other term for cyano bacteria is "blue-green algae". it is called so because from the word "CYAN" meaning greenish-blue colour and they are classified as bacteria. Cyanobacteria contain the same kind of chlorophyll that is found in green plants, but it is distributed throughout the cell rather than confined in chloroplasts. Other pigments mask the chlorophyll in many species and impart a bluish or sometimes reddish colour.

Cyan %26amp; bacteria?
Do you mean...

cyanobacteria

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

Can bacteria travel through space?

2009-11-20T03:58:00.003-08:00

Bacteria can definitely travel through space. Whether it will be intact after it hits a planet is the question. No bacteria currently on record could escape Earth's atmosphere on its own, but that isn't to say that a hearty spaceborne bacteria couldn't hitch a ride on a meteor impacting the Earth's surface. It is entirely possible we will see bacteria from space in our lifetimes. Of course, that bacteria will probably be defunct as if it survives in a vacuum. Any bacteria of this type would be anaerobic (without oxygen) and the introduction to our atmosphere would kill it. That is, unless there is a third type of bactera that can be both aerobic (survives in atmosphere) and anaerobic (survives with no atmosphere)

I would assume that some scientist in some country has thought to take bacteria samples to space to study the effects of a zero-g environment. In that sense, bacteria can travel through space, they just need a little help from a friendly researcher.

Can bacteria travel through space?
no, they can't survive
Reply:It is possible.
Reply:sure why not
Reply:Possibly inside of a meteorite, they think viruses can.
Reply:I guess its possible
Reply:no they cannot survive the vacuum
Reply:No they cannot because bacteria need oxygen to live like all living things but there are no oxygen in space so that's why astronauts bring oxygen tanks when they travel into space
Reply:It depends on the type of organism.If it is an anaerobic bacterium then it will definitely find it easier to travel through intersteller spaces.Some bacteria can survive at temperatures of 121 degrees and an acidic environment of 1-2pH also.Others are able to live on at temperatures as low as-20 degrees.
Reply:It can...and it has already. Look it up.
Reply:Yes they can travel as well as survive. see details:

On April 20, 1967, the unmanned lunar lander Surveyor 3 landed near Oceanus Procellarum on the surface of the moon. One of the things aboard was a television camera. Two-and-a-half years later, on November 20, 1969, Apollo 12 astronauts Pete Conrad and Alan L. Bean recovered the camera. When NASA scientists examined it back on Earth they were surprised to find specimens of Streptococcus mitis that were still alive. Because of the precautions the astronauts had taken, NASA could be sure that the germs were inside the camera when it was retrieved, so they must have been there before the Surveyor 3 was launched. These bacteria had survived for 31 months in the vacuum of the moon's atmosphere. Perhaps NASA shouldn't have been surprised, because there are other bacteria that thrive under near-vacuum pressure on the earth today. Anyway, we now know that the vacuum of space is not a fatal problem for bacteria.

What about the low temperature and the possible lack of liquid water in space? The bacteria that survived on the moon suffered huge monthly temperature swings and the complete lack of water. Freezing and drying, in the presence of the right protectants, are actually two ways normal bacteria can enter a state of suspended animation. And interestingly, if the right protectants aren't supplied originally, the bacteria that die first supply them for the benefit of the surviving ones!

VR
Reply:Yes, some satellites have been found to have had bacteria on the outside of them when their payloads were recovered by NASA. It is thought they went into a "suspended hibernation" type state and when returned to the heat and air came "back to life". Sort of like microbial life found in the permafrost near the polar regions. Take a chunk of permafrost ice, melt it and the microbes inside start moving again.
Reply:Some scientists believe that life on earth began with microbes that could have "hitched a lift" on a comet.
Reply:Bacteria have been found on the lense of one of the cameras tkaen to the moon during the apollo missions; so yes, they can travel through space
Reply:Free-floating bacteria anywhere near the sun (in earth's orbit?) would likely be killed by the sun's radiation, especially a full dose of ultraviolet light. Certain bacteria that need water molecules in their structure would likely dry up in the vacuum of space. Thus, bacterial escaping from earth would likely perish if not protected. This would also likely apply to bacteria arriving from outer space. The sun is a great sterilizing machine (capable of turning human skin red even on an overcast day!).
Reply:NO, they can't survive....they need appropraite enviorment to survive. Can u survive under water or without oxygen? your answer will be NO...in the same way bacteria need appropriate enviorment to survive.
Reply:It seems very possible although the evidence so far coming from man made objects (space probes, etc) has generally been debunked. As far as I am aware (that means I'm likely as not to be wrong here) nobody has ever performed a controlled experiment showing survival of bacteria entering earths atmosphere.

It isn't just bacteria likely to survive the cold and vaccuum though. There was a great experiment with a tardigrade in a scanning electronmicroscope. They evacuated the chamber, took loads of pictures and after opening up the chamber the little champion got up and walked off - thats tough!!

Which bacteria r deadly to humans?

botulism is about as deadly as you get.

edit. the toxin created by botulism is one of the most powerful toxins known to man. Mostly comes from food poisoning. (Wiki)

But with more resistant baceria becoming prevelent who knows. Luckily most bacteria can be taken care of with antibiotics nowadays, but that could change to where most strains of bacteria have become resistant to drugs to to overuse of antibiotics.
Reply:Any bacteria is deadly to humans it just depends on how strong your imune system is.
Reply:Bacterium are everywhere. There are so many types it is impossible to mention on here. Some are good for us and some are bad for us. If I were you I wouldn't worry about it, knowledge can be a bad thing, lol.

Antibacterial soaps kill the good stuff, and they themselves (for that reason) can make us sick.

Why food that has had bacteria growing on it can cause food poisoning even when the bacteria have been killed?

killed by cooking

Why food that has had bacteria growing on it can cause food poisoning even when the bacteria have been killed?
You can become intoxicated as in the case of Clostridium botulinum (botulism) or Staphylococcus aureus (caused by Staph. Super Antigens).

I am going to add, however, that those toxins are generally destroyed by cooking. But the theoretical answer to you question is definitely because the bacteria have secreted toxins which make you ill upon consumption.
Reply:who said that?

Cooking is to kill bacteria. Unless you mean like parasites etc. Not cooking well or thoroughly enough doesn't kill them (or kill them all) which causes food poisoning
Reply:Because the bacteria produce toxins as waste products in their growth. Heat can kill the bacteria but won't destroy the toxins. Botulism is a good example of this.
Reply:Bacteria secretes toxins that might survive cooking that kills the bacteria itself.
Reply:if the food has been cooked, then set on a contaminated surface-welcome to the world of food poisoning!! also if it is not cooked thouroughly some bacteria and parasites will form endospores that keep them protected until things are safe again. also, when people handle your cooked food after taking a bit **** and not washing their hands, that can make you sick as well.

Could bacteria grow on the streak plate and not be seen using the pour plate technique?

2009-11-20T03:57:00.000-08:00

If the bacteria was extremely sensitive to low oxygen, then it might not grow in pour plates because of the slightly reduced levels as you go deeper in the agar.

Could bacteria grow on the streak plate and not be seen using the pour plate technique?
I eat steak wunst in a great while. And I always eat it off a clean plate. I pour BarbieQ sauce on it. The plate gets sauce stains on it, of course.

Do bacteria require oxygen for growth?

2009-11-16T06:01:00.001-08:00

plsssssssssss help me!!!!!!

Do bacteria require oxygen for growth?
yes ofcourse they require oxygen for respiration if they are aerobic bacteria. oxygen helps in respiration to break sugars down to release energy used in cell mechanisms and growth.

this releases CO2.

however, there are anaerbic bacteria that dont require oxygen, but they require CO2.
Reply:Some do, some dont.
Reply:yes some catogaries like

facultative anaerobes and aerobes and microaerophiles
Reply:"Aerobic" bacteria do, "anaerobic" bacteria don't. The type name explains it all.
Reply:Yes... it does nid oxygen for growth...and mostly warmth
Reply:Yes, bacteria can survive without oxygen.
Reply:yes

Does bacteria and fungi benefit groundwater?

2009-11-16T06:00:00.003-08:00

There is no grass in groundwater. Groundwater is several feet under ground in most places. The water table (the top level of groundwater in aquifers) holds water that many towns drill into and pump the water up in wells to use. There isn't a lot of pollutants in the water because the soil cleanses the water on the way down to the groundwater. The only thing that needs to be done to make groundwater drinkable (potable) in most cases is to soften it. But, the bacteria do biodegrade (eat) a lot of the pollutants that do make it to the groundwater from leaks in storage tanks. So bacteria do act as a natural defense to pollutants.

Does bacteria and fungi benefit groundwater?
yes, because it in some wierd way it polinates the water system and makes the grass grow taller and it accually makes the chlorafil stronger.

Why does acidity effect bacteria growth -?

2009-11-16T05:59:00.001-08:00

there seems to be no websites on it :S if any one knows any?? or any books? cheers

Why does acidity effect bacteria growth -?
Bacteria digest externally through the use of enzymes.

The `PH' changes the effectiveness of the enzymes.

Eg. :Botullinus grows well in basic environments, but can't

grow in acid ones.
Reply:Some organisms only like low pH and some like high pH. It varies from organism to organism.

go here on the web page i cite

The Effect of pH on Growth
Reply:Acidity does not affect the growth of all organisms, otherwise the yogurt would not have been produced. However, in most cases, acid denatures vital proteins necessary for the growth of the organisms. Consequently, the organisms die in an acidic environment.
