Bacteria are both harmful and helpful to?
yep. look at yogurt.---being helpful...not harmful
Reply:Yeast is a helpful bacteria. Without it, there would be no bread as we know it.





Ecoli will kill you.
Reply:yeah bacteria is very helpful when it comes to your life. if you don't know this, your skin is covered with it. it helps when it comes to cheese and yogurt, it also decomposes a lot of the earths dead things, so that the earth can recycle.
Reply:Yeast is a fungus, not a bacteria.





Bacteria are both harmful and helpful to the digestive track--sometimes the same bacteria. Without E coli in our intestines, we wouldn't be able to digest food, but when it gets into our stomach, mouth, or bloodstream, it makes us very sick (like all the stories in the news lately about tainted spinach.)
Reply:Sometimes you have to kill a bacterial infection with antibiotics, right? Right. But antibiotics kill all bacteria, even the good ones you don't want to kill - for example, if on antibiotics too long, you may develop a yeast infection because the good bacteria that prevents yeast infections would have died along with the bad bacteria.

E coli lives in your colon. Only the O157 strain is harmful, without E coli in your colon you wouldnt be able to digest food. We have a mutualistic relationship with the gut flora- they digest our food, we give them a place to live.
Reply:Is cheese and yogurt harmful? Is gohnnorea and gangreen disease helpful?
