Brucelose bovina em matadouro com serviço de inspeção federal e municipal no estado do Maranhão

Abstract

Brucellosis is an infectious disease caused by bacteria of the genus Brucella. It is endemic in many countries, resulting in significant economic damage to production systems and notable implications for animal and public health, given its zoonotic nature. Infected animals act as a source of infection for humans through the ingestion of contaminated milk and derived products, handling of fetal meat, fetuses and membranes, blood and other tissues by occupational exposure of farmers, magarefes, veterinarians and employees who come in contact with the micro -body. There is concern in the understanding of the relationship between bursitis and direct or indirect detection of Brucella spp. in cattle. The objective of this study was to carry out the epidemiological study of bovine brucellosis in a slaughterhouse under Federal Inspection Service (SIF) and Municipal Inspection Service (SIM) in the State of Maranhão, with slaughter, from different municipalities of Maranhão and other regions of the country, For a period of one year through collection of blood during slaughter for analysis by the AAT and 2- ME tests. A questionnaire was applied with the owners to study the possible risk factors associated with brucellosis. 1265 bovine serum samples were collected, where 39 reagent samples were tested in the AAT test and 15 reagents in the 2-ME, of which only 1 reagent male. Of the 15 bursitis collected, only 01 was reactive in the 2-ME test, obtaining a prevalence of bovine brucellosis in a slaughterhouse in the state of Maranhão of 1.19%. It is concluded that Brucella abortus infection in animals slaughtered in slaughterhouses under Federal and Municipal Inspection Services in the municipalities of Imperatriz and Açailândia in the state of Maranhão is present, and occurs more frequently in females. The main risk factors for the disease are the occurrence of miscarriages on the farm, the sale of animals without tests and the failure to perform tests that test the animals before inclusion in the herds and before slaughter.
