Bovine brucellosis: Epidemiological situation in Brazil and disease control initiatives

Abstract

Bovine brucellosis caused by Brucella abortus is present throughout Brazil, whose prevalence distribution shows variations among states and within the productive areas of the states, causing serious losses to cattle production and public health due to risk of transmission to humans. Therefore, since 2001, the National Program for the Control and Eradication of Brucellosis and Tuberculosis (PNCEBT) is being implemented in all Federative Units of Brazil, based on the compulsory vaccination of bovine females, control of animal movement and certification of brucellosis-free herds. This review covers the current epidemiological situation of bovine brucellosis in Brazil, issues related to public health and economic importance, as well as Brazilian initiatives to control the disease.
