Bacillus cereus prosthetic valve endocarditis

Abstract

Bacillus cereus is a ubiquitous organism that often contaminates microbiological cultures but rarely causes serious infections. Reports of B. cereus endocarditis are infrequent. Infection in patients with valvular heart disease is associated with significant mortality and morbidity. We describe a case of B. cereus endocarditis involving a mechanical mitral prosthesis that resolved after replacement of the prosthetic valve. We also review the previous cases reported in the literature.
