Puma lentivirus (PLV) antibodies were detected in 13 (25%) of 52 serum
samples obtained from cougars (Felis concolor) collected by hunters.
The serum samples were collected from November 1993 through January 19
94 from four specific regions throughout the state of Washington (USA)
, and included the Olympic Mountains, the Cascade Mountains, the Blue
Mountains, and tile Selkirk Mountains. More (38%) seropositive cougar
samples originated from the Cascade Mountains than from any other site
. The overall seroprevalence for PLV; infection in Washington cougars
was higher than previously reported for cougars sampled in Oregon and
Idaho (USA), but lower than in cougars sampled.
