The taeniasis-cysticercosis complex is characterized by the presence of two distinct diseases, caused for the same parasite but in different life stages. The taeniasis is a disease provoked through the presence of the adult form of Taenia saginata or Taenia solium in small intestine of human. In as much, the cysticercosis is a disease provoked by the presence of larva these tapeworms, Cysticercus bovis and Cysticercus cellulosae, on the tissue of intermediate host. Besides the importance of taeniasis and cysticercosis for public health, animal health, and for the economy, the epidemiological reality of the occurrence of zoonosis in Brazil is not well known. The objective of this research was evaluated the epidemiological profile of the taeniasis-cysticercosis complex in the rural area of Viçosa-MG, through the determination of the prevalence of the swine, bovine, and human cysticercosis and the human taeniasis in the farm evaluated, in conformity to the sanitary and socioeconomic conditions. For this, the research was realized as a transversal study involving 176 rural properties in the city, where 226 swine blood samples and 240 bovine blood samples and feces of 266 residents in the rural area were collected, an epidemiological survey were applied and survey of the cases of neurocysticercosis were diagnosed by computed tomography in the São João Batista Hospital, located in Viçosa-MG. Stool examination was performed by a technical of direct microscopy investigation of eggs of Taenia sp. on glass slides. The serological diagnosis of the animal cysticercosis accomplished by the ELISA indirect test and the suspicious cases were submitted to Immunoblot for confirmation. This research indicated the predominance of 0.6% of swine cysticercosis and 0.42% of the bovine cysticercosis in the rural area of Viçosa- MG. No cases of human taeniasis were found despite of the high predominance of the other intestinal parasites. By computed tomography 14 suspected cases of the neurocysticercosis were diagnosed in patients of the rural area of the city. The sampled families were characterized as being low income families, provide untreated water to the animals, create animals for slaughtered without sanitary inspection, raise bovines and swine with low adoption of technology, use of the untreated water in the houses, which are all characteristics considerably favorable to the maintenance of the taeniasis- cysticercosis complex. Despite of the presence of the unfavorable facts of the control of that complex, the families have habits that are considered factors of protection to the development of those parasites, such as reared swine arrested, absence of open sewage system, and the non-ingestion of swine or bovine meat raw or undercooked. Even though this study has shown a low predominance of the cases of taeniasis-cysticercosis complex in the rural area of Viçosa-MG, it is necessary to continue epidemiologic and sanitary vigilance because the factors favorable to the maintenance of these parasite diseases exist.
