Prairie dogs (Cynomys spp.) are highly susceptible to Yersinia pestis and significant reservoirs of plague for humans in the western United States. A recombinant raccoon poxvirus, expressing the F1 antigen of Y. pestis, was incorporated into a palatable bait and offered to 18 black-tailed prairie dogs (Cynomys ludovicianus) for voluntary consumption; 18 negative control animals received placebo baits. Antibody titers against Y. pestis F1 antigen increased significantly (P < 0.01) in vaccinees, and their survival was significantly higher upon challenge with Y. pestis than that of negative controls (P < 0.01).
