My e-mail has been a little sloooooow.  So this may not be too timely or 
even relevant, but.........

<< 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.

I'll check this out with the physiologist who explained it to me--some bugs
thrive in one environment, others in another. I'll get back to you.

I've heard this too.  I don't have a source, but I do know that this 
concept is the basis for the development of Dyanmite's product 'Dynapro'.  
It's probiotic that has no live cultures in it.  It contains primarily 
distilled H20, lactobacillus extract and minimal amounts of B-vites & a 
couple other vites.  The lactobacillus and other "good" bugs like this 
'medium'.  The purpose of the product is to condition the environment of 
the gut, then the "good bugs" will grow.  It's the basically the same as 
Pro-bi, except without the herbs.  (When ABC spit off from Dynamite, they 
had to change the formula some because of patent or something like that).  
I'd be really interested in any research citation on this.
