Prevalence of Toxoplasma gondii antibodies in sera of hunter-killed white-tailed deer in Pennsylvania

Abstract

Serum samples from 593 white-tailed deer in Pennsylvania that were killed by hunters in 1991 were examined for Toxoplasma gondii antibodies, by use of the modified agglutination test. Sixty percent (357/593) of the deer had T gondii antibodies; 10% had titer of 25, 23% had titer of 50, and 27% had titer > or = 500. Sex-specific differences in prevalence were not detected.
