SEROPREVALENCE OF BRUCELLOSIS IN DAIRY CATTLE USING Brucella abortus ANTIGEN IN SYLHET DISTRICT

Abstract

Brucellosis is an economically important disease prevailing in Bangladesh. Because of its economic impact on animal reproduction and the risk to the human population, most countries have a brucellosis control program. The present study was carried out to determine the sero-prevalence of brucellosis in dairy cattle in Food Security for the Sylhet district of Bangladesh. A total of 120 dairy cattle sera samples were screened by Brucella abortus antigen which is a confirmatory and rapid test for proper diagnosis of the brucellosis. The overall serological prevalence derived from the samples was 1.67%. In conclusion, it is observed that, a higher prevalence of Brucellosis was found in aged animals than young; and aborted animals compared to non-aborted animal. The result showed that female animals were has more susceptible to infection of brucellosis. Some future recommendation to address this disease were:  Regular sero-monitoring of the dairy cattle need to be carried out.  Positive reactors must not be used in breeding purposes.  Replacements should be made with dairy cattle free from Brucella infection.  People involved in dairy cattle husbandry and meat handlers should not be handled anything without gloves if there is any suspection of brucellosis.  Livestock rearing personnel’s which are involved with dairy industry should be cautious about brucellosis.  Programs to raise awareness about this disease should be conducted.  Further studies for isolation, identification and typing of specific Brucella sp. are also recommended.
