title: Prevalence of toxoplasma antibodies in Southern Louisiana swine.
abstract: 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.
