SEROPREVALENCE STUDY OF BRUCELLA INFECTION IN CATTLE

Abstract

Brucellosis is a zoonotic disease infecting humans and animals. It causes a great economic losses in livestick industries through abortion, infertility, birth of weak and dead offsprings, increased calving interval etc. Bangladesh has been reported an endemic area for brucellosis. Because of its economic impact on animal health and the risk of transmission to human population most of the endemic countries have a brucellosis control program. The present study was conducted to determine the seroprevalence of Brucella infection in cattle in Bogra district. Among 100 sera sample, 58 sera were collected from Bogra Sadar Upazila and 42 sera were collected from Bogra Dairy Farm. The epidemiological history and blood was collected from the cattle of above mentioned area. The sera sample was subjected to Rose Bengle plate test (RBPT) for screening of brucella antibodies. The higher rate of brucella antibody was recorded (5.5%) in cattle of above four years of age, (4.05%) in female cattle, (5.17%) in cattle of Bogra Sadar Upazila, (5.4%) in naturally bred cattle, (4.76%) in aborted cattle, (6.06%) in pregnant cattle, (5.45%) in cross breed cattle and (4.62%) in grazing cattle. The prevalence of brucellosis in Bangladesh cow population is not negligible and it is worthwhile to consider adoption of preventive measures.
