Clostridium cadaveris (C. cadaveris), a strict anaerobic gram-positive rod, is rarely reported in clinical specimens. Since its detection in 1899, it has always been linked to the decay of dead bodies. C. cadaveris is considered non-pathogenic to humans, however infrequently it can cause severe infections including bacteremia. The latter was typically associated with gastro-intestinal pathologies. We report the first case of C. cadaveris invasive infection at Sultanate Oman. The source was most probably an infected decubitus ulcer.
