antibiotic resistance

I am cross posting all of this to newsgroups that can give you more of a
definitive answer to these inquiries.  If you don't take an adequate dose of
antibiotics to do the first time, the resistant bacteria will survive to come at
you again.  You can't just take a "weak dose" of antibiotic and expect it to
work.  All you're doing is setting yourself up for bacterial resistance.

I'm not sure that antibiotics "weaken" the immune system as much as they change
the symbiotic relationship of different strains of bacteria in the body.  For
example, if you take a broad spectrum antibiotic, it can kill off a lot of your
gram negative bacteria in your gut, allowing yeasts and bacteria like
Clostridium difficile, which causes pseudomembranous colitis, can overgrow.  The
levels of each kind of bacteria rearrange into a different balance depending on
what are affecting their growth.

If anyone from the other NG's have comments, please feel free to jump right in
here.
