Diagnóstico do complexo teníase-cisticercose bovina em São João Evangelista, Minas Gerais, Brasil

Abstract

In order to diagnose the situation of bovine taeniasis-cysticercosis complex in the state of Minas Gerais, Brazil, the city of São João Evangelista was selected, and blood samples were collected from 339 cattle in 15 randomly selected farms. A socioeconomic questionnaire was filled in each property for the analysis of the factors that favor the maintenance of the taeniasis-cysticercosis complex. Additionally, there was the diagnosis of human taeniasis verified by stool examinations of the properties' inhabitants. A prevalence of 4.1% for bovine cysticercosis and the frequency of 2.94% for human taeniasis were found. Among the risk factors, a statistically significant relation (p = 0.042) was found between the occurrence of bovine cysticercosis and the ingestion of undercooked meat. It was concluded that bovine cysticercosis is broadly distributed in the city of São João Evangelista, with rates considered endemic, being the consumption of raw and not-inspected meat the main risk factors for the maintenance of complex taeniasis-cysticercosis, reinforcing the need to adopt control measures with continuous epidemiological and health surveillance.
