Epidemiological profile of bovine and swine cysticercosis in three regions of Minas Gerais State, Brazil
ABSTRACT In order to evaluate the epidemiological situation of porcine and bovine cysticercosis in the rural area of five municipalities, distributed in three different regions of the state of Minas Gerais, Brazil, the prevalence of bovine and porcine cysticercosis was determined in the rural properties as well as the main risk factors that may favor the transmission and maintenance of the disease in these properties. The research covered 388 farms, located in 91 different rural communities, with 1,792 samples of bovine blood and 554 of swine collected. In addition to the evaluation of these laboratory samples (indirect ELISA and Imunoblot), the data obtained from the application of a questionnaire for each property were also analyzed, with information on socioeconomic, hygienic-sanitary and animal-related conditions. The prevalence of cysticercosis ranged from 0.3 to 5.9% in cattle and from 0 to 2.8% in the pigs raised in these municipalities. Among the main risk factors for transmission of bovine cysticercosis were the source of water consumed, the origin of the meat, the nature of the municipality and the region. Regarding the pigs, risk factors were the sewage disposal and animal management system.
