Sylvatic plague in a Canadian black-tailed prairie dog (Cynomys ludovicianus)

Abstract

In 2010, a black-tailed prairie dog (Cynomys ludovicianus) was found dead in Grasslands National Park, Saskatchewan, Canada. Postmortem gross and histologic findings indicated bacterial septicemia, likely due to Yersinia pestis, which was confirmed by molecular analysis. This is the first report of Y. pestis in the prairie dog population within Canada. © Wildlife Disease Association 2014.
