Since the discovery of the Pasteurella tularensis organism by McCoy (1911) in Tulare county, California, it has become widespread and an increasing problem . During the last year especially, Tularemia has become an important public health problem. The cases of human infection have almost always a history of having dressed or handled rabbits. Last year 211 rabbits were autopsied at the Diagnostic Laboratory. None of these showed lesions of Tularemia or yielded the organisms on culture or animal inoculation. On July 31, 1939 the first case of Tularemia was diagnosed. The rabbit was brought from near the Des Moines river a few miles south of Boone. The animal was observed in convulsions when first seen by the person submitting it. The rabbit died in a few minutes.
