Between November 2006 and March 2007, a total of 269 elk, 25 bison, 18 grizzly bear and 15 black bear blood samples were received by the FWP Wildlife Laboratory (WL) for testing. Of the specimens received, 135 elk, 12 bison, 18 grizzly bear and 15 black bear samples were deemed suitable for submission to the Montana Department of Livestock Veterinary Diagnostic Laboratory (MTVDL) for brucellosis serologic testing. In accordance with the State of Montana Brucellosis Testing Procedures (Appendix 1), elk specimens that tested positive or were classified as suspect were subsequently submitted for Western immunoblot (WB) testing. The state's Brucellosis Epidemiologist determines final exposure classification. Found at Yellowstone Center for Resources, Yellowstone National ParkNatureBib ID: 651979
