Resumo: Tendo em vista o conhecimento limitado sobre o diagnóstico da cisticercose bovina pelo immunoblot, o objetivo deste trabalho foi avaliar a aplicabilidade desse teste, identificando os principais peptídeos com valor diagnóstico. Foram realizados ensaios de immunoblot, utilizando antígeno total de larva de Taenia crassiceps e 60 soros de bovinos positivos para a cisticercose (30 naturalmente e 30 experimentalmente infectados com ovos de T. saginata), 30 soros de bovinos negativos para a cisticercose e 30 soros de bovinos com outras patologias (fasciolose, hidatidose e tuberculose). Os peptídeos de maior importância diagnóstica, em ordem decrescente de acurácia (%), foram os seguintes: 6-8 kDa (90,8%), 129-143 kDa (74,2%), 99-105 kDa (71,7%) e 14-19 kDa (71,1%). Reações cruzadas, em decorrência da fasciolose e hidatidose, foram observadas nos quatro intervalos de peptídeos ressaltados. Os resultados demonstram que o antígeno total de T. crassiceps possui peptídeos com alto potencial diagnóstico, sendo, portanto, o immunoblot útil no diagnóstico da cisticercose bovina.

Immunoblot assays were performed using total larval antigen of Taenia crassiceps and 60 sera of positive bovines for cysticercosis (30 naturally and 30 experimentally infected with T. saginata eggs), 30 sera of negative bovines for cysticercosis and 30 sera of bovines with other diseases (fascioliasis, hydatidosis and tuberculosis). The peptides of greater diagnostic importance, in descending order of accuracy (%), were as follows: 6-8kDa (90.8%), 129-143kDa (74.2%), 99-105kDa (71.7%) and 14-19kDa (71.1%). Cross- reactions, due to fascioliasis and hydatidosis, were observed in the four intervals of peptides highlighted. The results demonstrate that the total antigen of T. crassiceps has peptides with a high diagnostic potential; therefore, the immunoblot is useful in the diagnosis of bovine cysticercosis.
