I have read the statistics somewhere and doctors in the US have actually decreased prescription of anti-biotics. I’m pretty sure this isn’t terribly new news. I mean if gastros were doing fecal implants as early as 2010 to cure anti-biotic induced c.diff, then you would imagine there was a body of study eluding to gut flora wreckage by anti-biotics.
I can’t remember where I read it, but I think it was in Science, June issue. One of the articles in there. That whole issue was about the gut.
So, yes, for once I agree with FLoggi in that maybe most, but not all, of the doctors in the US are either aware of why they have to be sparing in the prescription of antibiotics, or at least aware they have to as per guidelines from the medical hierarchy.
