Seroprevalence of Brucellosis and Its Associated Risk Factors in Bovine at Greater Mymensingh District of Bangladesh

Abstract

Brucellosis is a zoonotic bacterial disease of humans and animals caused by Gram negative bacteria of the genus Brucella. The study was conducted to determine the sero-prevalence of brucellosis and its associated risk factors in cattle and buffalo in greater Mymensingh district, Bangladesh. Blood samples were collected from cattle (n=150) and buffalo (n=60). Sera were tested for Brucella specific antibody by the rose Bengal plate test (RBPT). Overall prevalence of brucellosis was 15.33% in cattle and 13.33% in buffalo. Higher prevalence was recorded in cattle and buffalo of over 4 years age (18% and 15.68%, respectively). Female animals showed higher brucellosis prevalence (cattle 19.54%, buffalo 13.46%) than male ( cattle 8.21%, buffalo 12.5%). Pregnant cows showed higher prevalence of brucellosis (13.33%) as compare to non pregnant cows (10%). The prevalence of brucellosis was 10% in aborted cows, 4% in the case of retained placenta and 2.85% in repeat breeder cows. The study suggests that brucellosis is prevalent in the cattle and buffalo and its prevalence is affected by the animals age, sex, pregnancy status and reproductive disorders.
