| Notes | E.F.G. Herbst. He fed "trichina"-infected badger flesh to three pups (in November 1850) and later observed larvae in the muscles of the pups at necropsy. Trichinella (then Trichina) was not then recognized as a pathogen; so, while this was the induction of infection by transfer of a pathogenic microorganism, it would not have been recognized as induction of disease. According to Foster, the discovery did not get the attention it deserved. Also in Grove. See Campbell, W. C. Trichinella and Trichinosis. Plenum, 1983. |
