Prevalence of Toxoplasma gondii antibodies in southern Louisiana swine in 1980 and 1981.
Sera from 1,219 pigs slaughtered in southern Louisiana in 1980 and 1981 were tested, using the indirect hemagglutination test and microtitration system, for Toxoplasma gondii antibodies; 19.19% had titers of greater than or equal to 1:64. Pigs slaughtered in the colder months, November to March, had significantly higher seroprevalences than did pigs slaughtered in the warmer months. Examination of blood samples from 236 sows and gilts on 52 farms revealed a seroprevalence of 24.6%.
