Brucella isolated from bone marrow.
A 40 year patient presented with pyrexia of one month duration. Routine work up for fever of unknown origin (FUO) was negative. Bone marrow aspiration and culture done yielded Brucella. Bone marrow cultures are recommended for patients for FUO for whom the routine workup turns out to be negative. Serological tests for brucellosis can be false-negative in some cases of brucellosis due to prozone phenomena.
