Brucellosis

Botulism, brucellosis, Lyme-disease and tetanus are infectious, but not contagious diseases.

There is debate asto whether rangiferine brucellosis spread to North America across the Bering Sea land bridge duringthelast iceage,orifit was introduced in imported Russian reindeer around 1900.

The clash between Montana and the National Park Service, among other officials and entities that maintain the sprawling park, stems from state authorities' belief that the park's plan to manage its bison herd doesn't do enough to reduce the risk of brucellosis transmission.
