Abstract

The aim of this study was to verify the prevalence of anti-Toxoplasma gondii antibodies in sera from naturally infected milk-producing caprines using indirect immunofluorescence assay (IFA) and modified agglutination test (MAT), determine specificity and sensibility of MAT and to evaluate the agreement of results between the tests. For this study, 282 caprine serum samples were collected from farms in the city of Pitanga, Paraná State, a region with a high pecuary of small ruminants. Prevalence found by IFA was of 44.68% and 23.05% by MAT. There was statistically significant difference (p=0.0086) in relation to the gender of animals, being females more seropositive. Sensitivity and specificity results for MAT were, respectively, 42.2% and 94.9%. By comparing results, a moderate agreement was observed (Kappa = 0.42). The high prevalence for the infection, associated to high titers found by IFA and clinical signs presented in the herds suggest toxoplasmosis as one of the causes of reproductive problems in caprines. Sensitivity and specificity results for MAT obtained in this study allow this test to be recommended as a confirmatory test for the caprine species.
