Resumo: | Toxoplasmosis is widespread zoonosis caused by Toxoplasma gondii , a protozoan that may infect mammals and birds. The aim of the present study was to assess the prevalence of T. gondii in ostriches (Struthio camelus) from commercial breeding facilities in the state of São Paulo, Brazil, in a way to increase the knowledge on the behavior and importance of the parasite in this animal species. A total of 195 serum samples were collected from ostriches from Sorocaba, Campinas, São Carlos, Araçatuba, São Paulo, Vale do Ribeira, Botucatu and são José do Rio Preto, in the state of São Paulo. These samples were analyzed by means of the Modified Agglutination Test (MAT) in order to investigate the occurrence of Toxoplasma gondii antibodies. The test showed that 14.36% of the animals were seropositive to Toxoplasma gondii. Minimum titer was considered to be equal or greater than 1:16, and the greatest dilution observed was 1:16,384. No statistically significant differences were found between males and females. Seronegative animals occurred in only two regions (São Paulo and São José do Rio Preto). These results point out the importance of further studies on this infection in ostriches, and on management practices that may minimize the risk of toxoplasmosis transmission in these birds which would, in their turn, decrease the risk for the final consumer. |

O presente estudo teve como objetivo estimar a prevalência do Toxoplasma gondii em avestruzes (Struthio camelus) de criatórios comerciais do estado de São Paulo, como forma de auxiliar no conhecimento do comportamento e importância do parasito nesta espécie animal. Foram colhidas 195 amostras de soro de avestruzes, provenientes de Sorocaba, Campinas, São Carlos, Araçatuba, São Paulo, Vale do Ribeira, Botucatu e São José do Rio Preto, estado de São Paulo. As amostras foram analisadas pela Técnica de Aglutinação Direta Modificada (MAT), para a pesquisa de anticorpos anti - Toxoplasma gondii. Os exames sorológicos revelaram 14,36% de animais sororreagentes ao T. gondii. A titulação mínima considerada foi a diluição maior ou igual a 1:16, e a maior diluição encontrada foi 1:16384. Não foi constatada diferença significativa entre os sexos. Apenas duas regiões (São Paulo e São José do Rio Preto) não apresentaram animais sororreagentes. Esses resultados salientam a importância de um estudo mais aprofundado sobre a infecção em avestruzes, e também sobre as práticas de manejo que venham a minimizar o risco de transmissão da toxoplasmose para essas aves e, por conseqüência, para o consumidor final.Universidade de São Paulo.
