Brucellosis in sheep and goat of Bogra and Mymensingh districts of Bangladesh / 대한수의학회지

Brucellosis is the most important bacterial disease of livestock in Bangladesh. The present study was conducted to determine the seroprevalence of brucellosis in goat and sheep in Mymensingh and Bogra districts of Bangladesh using slow agglutination test and Rose Bengal test as screening test and indirect enzyme linked immunosorbent assay as confirmatory test. Questionnaire based data on age, gender, area, client's complaint, number of animals in herds, disease history, reproductive problems such as abnormal uterine discharge, abortion or previous abortion in sheep and goat and their reproductive diseases were recorded. A total of 200 sera samples were collected from 80 sheep and 120 goats. The prevalence of brucellosis in goat was 2.50% and 1.25% in sheep. Positive reactors were only detected in female of both goat and sheep. In this study, there existed a significant association among abortion and the prevalence of brucellosis (p < 0.01). The prevalence of brucellosis in sheep and goat in Bangladesh is not negligible, and it is therefore worth considering the adoption of preventive measures.

Prevalence of Brucella antibodies in sera of cows in Bangladesh

The study was carried out to investigate the prevalence of Brucella antibodies in sera of 120 cows in Bangladesh Agricultural University Dairy Farm and adjacent villages, Bangladesh. The epidemiological history and blood was collected from the cows. The serum samples were subjected to Rose Bengal Test (RBT)and plate agglutination test (PAT) for initial screening of Brucella antibodies and the positive sera samples were then subjected to tube agglutination test (TAT)for further confirmation. The higher rate of Brucella antibody was recorded in rural farm (5.0%)than organized farm (2.5%)and in pregnant cows (5.9%)than non-pregnant cows (4.7%). A total of 3 (4%)Brucella positive antibody cases were recorded in cows of above four years of age whereas, 1 (2.3%)positive case was found in cows of less than 4 years of age. The study revealed that number of Red Shindi was the highest and the prevalence of brucellosis in Bangladesh cow population is not negligible and it is worthwhile to consider adoption of preventive measures.
