Abstract

Peru is an endemic country for Brucellosis, consequently, there is a risk of transmission through donated blood, by not to be part of regular screening carried out by blood banks. To determine the prevalence of antibodies against Brucella in the donor blood bank from Edgardo Rebagliatti Martins Hospital (Lima, Peru), were analyzed 1003 samples of blood donors. The screening was Rose Bengal test (RB); the positive samples were evaluated by tube agglutination test (AT) and 2- mercaptoethanol test (2-ME). Two donors were positives to RB, and confirmed by AT and 2-ME, was found a prevalence of 0.20% (99%CI: 0.10-0.92). It showed the presence of carrier donors of anti-Brucella antibodies with possible active brucellosis, was demonstrated, being evidenced the possibility to infection transmission. More studies have to be made to know the reality in other blood banks.
