Abstract

Bacillus cereus is a widespread organism in nature and a member of the B. cereus group of catalase- positive, aerobic, spore-forming, Gram-positive bacilli. B. cereus found in blood is often dismissed as a contaminant in the absence of repeated isolation from multiple cultures. Soft tissue and bone infection due to B. cereus have been associated with trauma, intravenous drug use, and an immunocompromised state. We report a very late prosthetic joint infection of the hip joint and consequent bacteremia caused by B. cereus, which occurred 13 years after total hip replacement surgery in the absence of recent trauma or intervention.
