Abstract

A total of 242 milk and 208 blood samples of goat were collected from three organized goat farms and surrounding rural areas of Bangladesh Agricultural University to determine the prevalence and associated risk factors of brucellosis in Black Bengal goats during the period from December 2008 to September 2009. Milk samples were screened by Milk Ring Test (MRT) and serum samples by Rose Bengal test (RBT) and Micro Agglutination Test (MAT) for detection of brucella specific antibody in milk and blood respectively. The overall prevalence was recorded as 13.64% in milk by MRT; 3.85% and 3.37% in serum by RBT and MAT respectively. About 21.21(7/33) % and18.18 (6/33) % of MRT positive goat showed positive reactions in RBT and MAT respectively. Does aged up to 4 years had lower prevalence (3.70%) of brucellosis than those aged over 4 years (12.50%). About 2.1 (odds ratio, OR = 2.1; 95% CI: 1.21- 4.53) and 47.1(OR = 47.1; 95% CI: 5.3- 416.6) folds increased odds of seropositivity of brucellosis were observed in aborted and placental retention cases respectively. Significantly (p<0.05) higher prevalence of brucellosis was recorded at late lactation stage (17.94%) than those were in mid (16%) and early lactation stage (11.76%). A significantly higher odds of seropositivity of brucellosis was observed in does (OR = 23; 95% CI: 3.08- 173.62). About 7 folds (OR = 6.8; 95% CI: 1.13- 5.32) increased odds of seropositivity was observed in pregnant does.
