Animal cysticercosis in indigenous Brazilian villages.
Sanitary inspection of beef and pork meat has been the major tool for diagnosing animal cysticercosis and for preventing taeniasis in Brazil. The indigenous villages Jaguapiru and Bororo are located close to the urban area of the municipality of Dourados in the State of Mato Grosso do Sul, Brazil, where precarious basic sanitation conditions are observed. Both cattle and pigs are raised for self-consumption of meat and milk as well as for sale on the external market, generally without official sanitary inspection. In this study, 96 bovine carcasses and 117 pig blood serum samples from animals raised in these indigenous villages were evaluated for the presence of metacestodes by postmortem evaluation, and anti-Taenia sp. antibodies were investigated using the indirect ELISA test. Metacestode forms were observed in 18.7% of the bovine carcasses, and 9.4% of the pig serum samples were positive for anti-Taenia sp. antibodies. The occurrence of animal cysticercosis in the villages may favor the occurrence of this zoonosis in the indigenous populations. Enforcement of proper slaughter and sanitary inspection conditions are urgently needed for controlling the taeniasis-cysticercosis complex among the indigenous population.
