Maybe in addition to the above mentioned work, but I was referring
to extensive work on yeast culture and it's effects on gastrointestinal
microflora under different circumstances.
Finally, and I don't know much about this, but it seems that you can

Isn't good bugs and bad bugs a relative thing? Why would some bacteria
be killed and not others when the causative agent is from environmental
effects? Seems to me that a mixed bag of bacteria living under similar
conditions would be more or less susceptible to the same things, which
is why antibiotics kill off entire populations, not just "bad" bugs.
