Seroprevalence of brucellosis in buffaloes in Bagerhat and Mymensingh district, Bangladesh

An experimental survey was conducted to determine the seroprevalence of brucellosis in buffaloes in Bagerhat and Mymensingh regions of Bangladesh. A total of 70 sera samples were collected from the study of which 24 were collected from Bagerhat and 46 were collected from Mymensingh district. Questionnaire based data on risk factors were collected for buffaloes. The samples were screened by Rose Bengal Test (RBT). Positive, doubtful and negative samples were further confirmed with indirect Enzyme Linked Immunosorbent Assay (i-ELISA). The overall serological prevalence of brucellosis was 4.28%. It was observed that, a higher prevalence of brucellosis was found in female than male; aged animal than young animal with reproductive disorder than animal without reproductive disorder and a history of previous abortion was associated with the higher prevalence of brucellosis than that of other reproductive diseases. The result showed that female animal has more possibilities of infection to brucellosis. Among the 1.3 million of buffaloes in Bangladesh, a considerable number of buffaloes have reproductive dificulties and Brucella infection is one of them. Since brucellosis is a zoonotic disease and a number of human being are at risk, the detailed epidemiological studies along with prevention and control strategies are necessary.
