Seroprevalence of brucellosis in Kashmir (India) among patients with pyrexia of unknown origin.

ABSTRACT

Over a period of 5 years from 1992 to 1997 a total of 3,532 patients of pyrexia of unknown origin (PUO) were subjected to Wright's tube agglutination test for brucellosis. Of the 3,532 patients tested, 28 (0.8%) were found seropositive for brucellosis. Males outnumbered females by a ratio of 31. Whereas the seroprevalence among males clearly was age-related, the seroprevalence among women was not. The highest number (43%) of positive males belonged to the age group 21-30 years. The majority of patients had titres of 1160 or 1256, high titres of 1512 and 11024 were found in 21.4% patients.
