Resumo: Three hundred and thirty nine serum samples were taken from sheep from Londrina region of the Paraná state, Brazil. Samples were analyzed by indirect immunofluorescence assay (IFA) for the detection of anti-Toxoplasma gondii IgG antibodies. Titers higher or equal to 64 were considered positives. One hundred and eighty five (54,6%) of the 339 samples tested were seropositive, with titres ranging from 64 to 65.536. All farms had positives animals. There was a statistical significant difference between seroprevalence to T. gondii and age. No significant difference was observed in the association between seropreva Londrina region of the Paraná state, Brazil. Samples were analyzed by indirect immunofluorescence assay (IFA) for the detection of anti-Toxoplasma gondii IgG antibodies. Titers higher or equal to 64 were considered positives.

There was a statistical significant difference between seroprevalence to T. gondii and age. No significant difference was observed in the association between seroprevalence and sex. It was not possible to associated T. gondiiseroprevalenceand presence of housed or stray cats, because these animals were present in all farms. The present work showed that T. gondii has a wide distribution in sheep from this region.

Foram observados 185 (54,6%) ovinos sororeagentes ao T. gondii, com títulos variando de 64 a 65.536. Todas as propriedades apresentaram ovinos sororeagentes. Animais com idade igual ou maior a dois anos, apresentaram um maior número de sororeagentes, e não foi observada diferença estatística significativa quanto ao sexo. Não foi possível associar a soropositividade para T. gondii com a presença de gatos domiciliados e/ou errantes, uma vez que foi constatada a presença desses animais em todas as propriedades. A partir dos dados obtidos neste estudo, conclui-se que a toxoplasmose está presente no rebanho ovino da microrregião de Londrina no Estado do Paraná.UEL2003-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/211610.5433/1679-0359.2003v24n1p57Semina: Ciências Agrárias; Vol. 24 No. 1 (2003); 57-62Semina: Ciências Agrárias; v. 24 n. 1 (2003); 57-621679-03591676-546Xreponame:Semina.
