Abstract
This study was designed with a view to determine the prevalence and risk factors associated with bovine tuberculosis infection at several dairy farms of Rangpur division of Bangladesh. In this study, 150 calves of different age, breed and sex of several dairy farms in Rangpur division of Bangladesh were examined to determine the prevalence of tuberculosis by caudal fold tuberculin test (CFT) using bovine purified protein derivatives (bPPD) obtained from a licensed laboratory in India (Span diagnostics ltd). In the CFT, the percentage of positive reaction (reactors) was found 33.73. In general the younger cattle (6-12 months age) were found to be less infected than the older (5-7 years age) cattle in this study. Because of the danger of bovine tuberculosis to the public health, directly or indirectly and because of the apparently low incidence of bovine tuberculosis, it might be suggested that the infected animals should be slaughtered and destroyed without delay. It might be suggested that for obviously complete eradication of tuberculosis from the country, there should be very well coordination in activities among the public health and veterinary public health personnel.
