Prevalence of toxoplasma antibodies in Southern Louisiana swine.
Sera from 1,219 pigs slaughtered in Acadian Louisiana in 1980 and 1981 were tested using the indirect hemagglutination test and microtiter system for toxoplasma antibodies and 19.2% had titers of 1:64 or higher. Pigs slaughtered in the colder months, November to March, had significantly higher seroprevalences than pigs slaughtered in the warmer months. 24.6% of 236 farm bled sows and gilts had similarly high titers.
