Brucella agglutination titre in febrile versus healthy cases

ABSTRACT

Brucella tube agglutination test was performed to measure brucella antibody titre in 55 clinically healthy individuals [Controls], and 45 febrile patients due to custom to drink unpasteurised milk. Brucella antibodies were detected in 20 [36.3%] healthy subjects with titre ranging from 115 to 160, while the rest 35 [63.7%]. had negative titre. From the ferible group, 36 [80%] patient had positive titre. The highest antibody titre [1960] was observed in two cases who had clinical manifestations suggestive of brucellosis, and their repeated blood cultures were positve for brucella organisms. Out of 7 typhoid fever cases, 5 cases [70.4%] had titres ranging from 160 to 1240, but with no rising titres in subsequent estimations. Fever of other aetiologies were either negative or positive at low levels for brucella agglutination titres, the significance of these results had been discussed
