Bovine tuberculosis in the state of Rio Grande do Norte based on secondary data

Abstract

ABSTRACT: This study determined the frequency of positive tests for bovine tuberculosis in animals and breeders/establishments in Rio Grande do Norte, Brazil. Data were provided by the Instituto de Defesa e Inspeção Agropecuária do Rio Grande do Norte (IDIARN), from its Unidade Local de Sanidade Animal e Vegetal (ULSAV’S), acquired in monthly reports issued by qualified Veterinarians under the National Program for the Control and Eradication of Brucellosis and Animal Tuberculosis (PNCEBT), from June 2012 to December 2021. For diagnosis, the comparative cervical test was used as a routine and confirmatory test. A total of 45,804 cattle were tested, 53 (0.1%) of which tested positive. Secondary data are essential in the evaluation of sanitary measures, allowing rapid generation of hypotheses about diseases and providing support for decision-making. Measures such as raising awareness among producers, sanitary control in the acquisition and sale of cows for reproduction, inspection of sanitary barriers, and conducting epidemiological surveys to understand the actual situation of this disease in the state of Rio Grande do Norte are crucial.
