We report that Brucella abortus and Brucella melitensis agglutinate human (A+ and B+), hamster and rabbit erythrocytes, a heretofore undescribed feature in this genus. This activity was associated with a 29-kDa surface protein (SP29) that bound selectively to these erythrocytes and this binding was inhibited by rabbit anti-SP29 antibodies. Hemagglutination was inhibited by pretreatment of erythrocytes with neuraminidase and by preincubation of B. abortus with chondroitin sulfate, N-acetylneuraminic acid and N-acetylneuramin-lactose. © 2002 Federation of European Microbiological Societies.
