Sero-prevalence of brucellosis among abattoir personnel of Delhi.

A total of 165 serum samples of abattoir personnel of Delhi were tested by Rose Bengal Plate test (RBPT), Standard tube agglutination test (STAT), Complement fixation test (CFT) and Dot-Enzyme linked immunosorbent assay (Dot-ELISA). The Seroprevalence was 20.60, 12.75, 50.30 and 25.45 percent, respectively on the basis of RBPT, STAT, CFT and Dot-ELISA. Seroprevalence was highest among blood collectors (99.77%) followed by miscellaneous group (72%), animal handlers (68.96%), butchers (68.00%) and sweepers (57.14%). Among veterinarians, Seroprevalance was 28.57%. The Seroprevalence was more among persons of higher age group. The study indicates that abattoir personnel are at high risk to infection with brucellosis.
