Two hundred fifty-five lynx (Felis lynx) carcasses were collected from trappers in Interior Alaska (USA). Serosanguinous fluids were collected from the chest cavity of each carcass. These fluids were tested for evidence of exposure to Toxoplasma gondii by means of a modified agglutination test using formalin fixed tachyzoites and mercaptoethanol. Thirty-nine of the samples had titers greater than or equal to the threshold (> or = 25). Antibody prevalence differed between areas, and was directly related to age of the host.
