Factors affecting apparent prevalence of tuberculosis and brucellosis in wood bison
Summary Bison ( Bison bison ) abundance in Wood Buffalo National Park, Canada, declined from in excess of 10 000 bison in the late 1960s to a low of 2200 bison in the late 1990s. Bovine tuberculosis ( Mycobacterium bovis ) and brucellosis ( Brucella abortus ), were introduced to Wood Buffalo Nationa...
