Feline plague in New Mexico: report of five cases.

ABSTRACT

Naturally acquired plague was diagnosed in 5 domestic cats. The cats apparently contracted the disease through contact with sylvatic rodents or their fleas in plague-enzootic areas. The diagnosis was confirmed by direct immunofluorescence and isolation of Yersinia pestis on culture of abscess material. Abscess formation, lymphadenitis, lethargy, and fever were consistent clinical findings.
