Plague in free-ranging mammals in western North Dakota.

Abstract

From July through October of 1996, 48 blood samples were collected from coyotes (Canis latrans), badgers (Taxidea taxus), and raccoons (Procyon lotor) in western North Dakota (USA) for the purposes of determining antibody titers to the plague bacterium, Yersniia pestis. The passive hemagglutination paper-strip blood-sampling technique was utilized with hemagglutination inhibition controls. Two positive samples were obtained from McKenzie county, one from a coyote with a titer of 1:64 and one from a badger with a titer of 1:256. Considering coyote and badger population dynamics, this study documents plague in western North Dakota.
