Levantamento sorológico de brucelose em bovinos monitorados no Estado da Bahia

Abstract

Brucellosis is a bacterial disease of great importance to the livestock economy and to public health because it is a zoonosis. It is an infectious disease that has etiologic agent with bacteria of the genus Brucella. In cattle, the species of the genus Brucella is Abortuscoccobacilli that are gram negative, facultative intracellular, real estate and not sporulated. The infection presents chronic and affects animals of all ages, being more frequent in sexually mature individuals. . This study aimed to investigate through serology for brucellosis, using the technique of indirect ELISA, samples from positive animals slaughtered in slaughterhouses inspected in the state of Bahia. 666 animals, randomly selected at slaughter were used. Blood was collected in order to obtain serum, all samples were subjected to a screening test Antigen Buffered Acidified (AAT), proof of 2-mercaptoethanol (2-ME) and Indirect ELISA. Of reagents in the test samples of AAT obtained an estimated prevalence of 1.2%. The prevalence in the ELISA test was 13.21% (n = 86). This result suggests the occurrence of false negatives when using the buffered acidified antigen test.
