> I am astonished by the letter from Bernadette Dunham, the director of the Food and Drug Administration’s Center for Veterinary Medicine, especially since she told a House committee on April 9 that she was unsure how antibiotic resistance develops.
I've posted this before, but some people may have missed it.
They have a slab of jelly. The jelly has sections of differing strength of antibiotic. There's a section with no antibiotic, then 10x, then 100x then 1000x. (They cannot dissolve any more antibiotic into the jelly at that point.)
A time lapse camera shows the bacteria growing, and developing resistance to each section.
