brucellosis

Bison carry brucellosis which causes miscarriage in cattle. Slaughtering bison who wander out of Yellowstone National Park to protect livestock has been a controversial management practice for decades. Superintendent Dan Wenk spoke out on the issue this week.

State wildlife and livestock officials say an elk captured in southwest Montana tested positive for exposure to brucellosis.

This is the first time a positive test was found in the Tendoy Mountains Southwest of Dillon, said officials from the Montana Department of Livestock.

A heifer has tested positive for the disease brucellosis on a cattle ranch near Yellowstone National Park. 

Yellowstone National Park has decided to convert part of its bison trap into a temporary brucellosis quarantine facility. 

On NPR's All Things Considered Sunday, Amy Martin reported on the second-largest ever cull of Yellowstone Bison this winter.

More than 1,200 bison were killed, more than at any time since 2007-2008.
