Seroprevalence of brucellosis in buffaloes in North India

Brucellosis is an infectious disease characterized by abortion and infertility in several mammalian species including buffaloes, and is one of the most important zoonosis worldwide. The objective of present study was to establish the seroprevalence of brucellosis in buffaloes in North India and to know the exact causal species of Brucella organism. A total of 160 serum samples were analyzed. The seroprevalence of Brucellosis was 4.38% and 7.50% by Rose Bengal Plate Test (RBPT) and Standard Tube Agglutination Test (STAT), respectively. Seroprevalence was zero by both RBPT and STAT in organized dairy farm while in unorganized sector, 5.04 and 8.63% by RBPT and STAT, respectively. Age-wise seroprevalence was higher in 4.5 to 6 years old buffaloes than younger. Area-wise seroprevalence was higher in Satwari block of study area. On screening of 20 milk samples from serological positive and doubtful buffaloes by milk ring test, five samples were positive (25%). On isolation of from samples, only one sample yielded Brucella abortus. The results showed that younger buffaloes were less infected than adults. Prevalence of Brucellosis was higher in Satwari block of Jammu province compared to other study area. The presence of Brucellosis in bovine may pose a significant economic loss to the farmer and a public health hazard to the general population.
