Prevalence of antibodies for Toxoplasma gondii in the sera of pedigree swine in the state of Santa Catarina

Abstract

The indirect haemagglutination inhibition test was utilized to determine the prevalence of antibodies to Toxoplasma gondii in pedigree swine from 61 farms, representing 61.2% of the total purebreed breeders affiliated to the Associação Catarinense de Criadores de Suínos. Sera samples of 1.033 swines were analysed. Twelve samples (1.16%) from seven herds (11.47%) were considered positive. The sera titles ranged from 1:64 to 1:512. Sera with title equal or higher than 1:64 were considered positive.
