susceptibility of the siberian polecat to subcutaneous and oral yersinia pestis determine if the siberian polecat (mustela eversmannii) represents a suitable model for the study of plague pathogenesis and prevention in the black-footed ferret (mustela nigripes), polecats were exposed to 10(3), 10(7), or 10(10) yersinia pestis organisms by subcutaneous injection; an additional group was exposed to y. pestis via ingestion of a plague-killed mouse. plague killed 88% of polecats exposed to y. pestis (71% mortality in the 10(3) group, 100% mortality in the 10(7) and 10(10) gr ...200111763738
experimental infection of domestic ferrets (mustela putorius furo) and siberian polecats (mustela eversmanni) with yersinia pestis.eight domestic ferrets (mustela putorius furo) and two siberian polecats (m. eversmanni) were inoculated subcutaneously with 12 to 1.2 x 10(7) yersinia pestis originally isolated during an epizootic of plague in white-tailed prairie dogs (cynomys leucurus) near meeteetse, park county, wyoming (usa) in 1985. none of the ferrets or polecats developed clinical signs of disease which suggested that black-footed ferrets (m. nigripes), a congener, also would be resistant to plague. all animals receivi ...19911920664
