Prevalência de cisticercose bovina em carcaças de frigorífico da Região Nordeste da Bahia

Abstract

Cysticercosis is a parasitic disease, considered zoonosis, caused by the presence of larval forms of Taenia saginata (Cysticercus bovis), bovine tissues and Taenia solium (Cysticercus cellulosae), in swine tissues, of which man is the definitive host, which ing viable cysticercus can contract teniasis. Bovine is the intermediate host that acquires Cysticercosis by ingesting T. saginata eggs from infected human faeces, which can subsequently contaminate pastures, vegetables, and water. This zoonosis is characterized by a low rate of technical development in animal husbandry and lack of basic sanitation. Both this parasitic disease and human teniasis can and should be controlled through basic sanitary measures. These measures are inspected by the sanitary inspection service inside the slaughterhouses, since it is frequently found in the slaughter line of the bovine species. The present study reports the prevalence of cysticercosis in cattle slaughtered in a refrigerator situated in the northeast of Bahia under the official inspection service, where 190,461 bovines were inspected between 2014 and 2016. The information regarding the names of the properties the total number of animals slaughtered in each batch and cases of cysticercus live 0.005% and calcified 0,63% in the lots evaluated. The presence of the parasite was detected in viscera such as liver and heart; head and tongue for a total of 1,204 animals. There was a higher prevalence of calcified cysticercus found in the liver 0.46% and in the heart than live cysticercus 0.14% found in all studied parts.
