ABSTRACT

A total of 1170 cattle and buffaloes serum samples were collected from Karnataka, Uttar Pradesh and Uttarakhand states to study seroprevalence of brucellosis using Rose Bengal plate agglutination test (RBPT) and standard tube agglutination test (STAT). Of the 425 animals from 5 organized farms of Karnataka, 126 (29.64%) and 135 (31.76%) animals were found positive by RBPT and STAT, respectively. From 366 serum samples collected from 5 unorganized farms, 47 (12.84%) and 81 (22.13%) animals were found positive by RBPT and STAT, respectively. In Uttar Pradesh 344 samples were collected from 5 organized farms, out of which, 46 (13.37%) animals were found positive by RBPT and 49(14.24%) by STAT for brucellosis. Screening of 35 animals from an organized farm of Uttarakhand, revealed 2 (5.71%) samples each positive by both RBPT and STAT. Overall out of 1170 samples collected from 3 states, 221 (18.88%) and 267 (22.82%) were found positive for brucellosis by RBPT and STAT, respectively. Based on results, it was found that Brucella infection is widely prevalent in organized and unorganized dairy farms in these states of India.
