Seroprevalence of Brucella abortus antibodies in the cattle population in the selected upazilas of Sirajgonj district

Abstract

A study was carried out on 135 commercial dairy farms of five upazillas of Sirajgonj district to know the prevalence of Brucella abortus antibody in herds during the period from January 2012 to December 2013. A total of 270 blood samples were tested by Anigen® Rapid Brucella Ab test kit. The overall prevalence of bovine brucellosis was recorded as 8.51%. Distribution on the basis of breed, age, sex and pregnancy revealed the significant relationship among the infection, breed, sex, age and pregnancy in the population. The prevalence was relatively high in older cattle (9.09%) and the highest prevalence was 9.34% in the pregnant female. The prevalence of Brucella abortus antibody was considerably high in most of the large herds. Further study is needed to know the species and biovar of Brucella circulating in the study area.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19127 Bangl. J. Vet. Med. (2013). 11 (2): 127-130
