It's mainly antibiotics, rather than disinfectants,
that are the problem. You can kill all bacteria
with fairly routine disinfectants. |
|
| |
Another problem is that bacteria don't really
crowd eachother out in most situations. They will
compete for nutrients (rarely for space), but when
these run out many bugs will just lie dormant for
weeks, months or years. |

Put it another way - if a bacterial population
carries a resistance plasmid, and you remove the
selective pressure, most individuals will lose the
plasmid over time. However, it's very rare for
_all_ individuals to lose it, and it will generally re-
emerge as soon as you reapply the antibiotic. |

The main reservoirs of bacteria in hospitals tend
to be patients and doctors, but these could of
course be autoclaved. |

Well, the premise of the idea was the baseless assumption that resistant bacteria would be weaker in some other manner than non, so the non-resistant would crowd it out if the antibiotics were removed and food sources added. |
|

Of course I've little clue as to what the difference between disinfection and antibiotician is. |

Ah - OK. Well, as an idea based on no information
it's excellent. |
