Abstract
The performance of an ELISA for detection of total antibodies to Bruceila spp. was compared with that of the Rose Bengal, standard agglutination and Coombs test in the diagnosis of brucellosis. Sera tested were from 208 patients from whom Brucella melitensis had been isolated, 177 patients with significant results in at least two conventional tests, and 107 patients with fever from whom no Brucella spp. had been isolated and in whom all conventional tests were negative. ELISA was the most sensitive test (97 %), showing greater specificity (96 %) and good predictive positive and negative values (98 % and 94 % respecitvely). ELISA was the only positive test in 6 % of patients in whom brucellosis had been confirmed by culture.
