Bacteria immune to rubbing alcohol?

Can typical baterial ever become immune or resiliant to rubbing alcohol like they are becoming to current animicrobials and antibacterials?

Bacteria immune to rubbing alcohol?
There are a few strains of bacteria that can live in different types of alcohol. They are very rare and need other specific conditions to live, so alcohol wipes are still a pretty good antiseptic hand or surface treatment. Alcohol will never sterilize any surface.


YboyP is partially correct to mention osmotic forces, but is mostly full of doodie. The alcohol would tend to pull water out of the organism via osmosis, but the alcohol would also typically be destroying the cell wall and killing the bugs more directly. Osmosis is slow and alcohol evaporates quickly. Also, Rubbing alcolhol (more properly Isopropyl alcohol) is also toxic and kills microorganisms this way also.
Reply:No.
Reply:it depends on the bacteria...just like different types of bacteria can resist different temperatures, I imagine, some of them can also resist rubbing alcohol...or become immune to it
Reply:There are two aspects of this. The chemical composition of the ellements and matter present and the reaction. Bacteria react to anti-biotics since they are a mild form of the bacteria itself or food chain of prey.





Some bacteria feed on others without cousing anyphsical of chemical damage to the surrounding. This applies to the anti-biotics while the alcohol simply explodes the bacteria by osmosis coz it has less Ph than bacteria so bacteria cannot be resistant to the alcohol.
Reply:yes it is possible. Any strains of bacteria can become resistant to almost any sort of anti-microbial. That is why most microbiologists will tell you that you shouldn't buy cleaning products with such chemicals that kill everything that it comes in contact with. Most germs you come across in your home don't need them or the chemical Triclosan.
