You would have thought they would have learnt that setting themselves up to fail is dumb ... but the latest NAVS leaflet repeats yet again as its first point the lie (for that is what it is) that pencillin kills guinea pigs but not people; ergo all animal testing is useless.

Fact: Giving penicillin to guinea pigs selectively kills bacteria in their gut, which allows the bacteria Clostridium difficule to overgrow, and this bacteria produces a toxin that can kill (Med Microbiol Immunol (Berl). 1981;169(3):187-96).

Fact: Giving penicillin to people selectively kills bacteria in their gut, which allows the bacteria Clostridium difficule to overgrow, and this bacteria produces a toxin that can kill (Health Protection Agency).

And of course that does not mean that 1000’s of guinea pigs are used to test for this bacteria. As in the vast majority of modern medicine and science advanced techniques (ie alternatives!) have replaced animal use (Clin Microbiol Infect. 2006 Feb;12(2):184-6).

I didn’t bother to read on.

Another ASA ruling?
