OK, I agree, there is not enough solid evidence for the idea that
antibiotic resistance is being fostered by bad care. However, I think
that enough evidence is available to warrant further investigation. "Big,
Bad drug companies" such as yours are certainly scientifically and
financially capable of helping to find out if such resistance is
spreading...after all, R&D is (hopefully) a major part of your budget.
Thanks for your thoughtful reply,
