Corynebacterium CDC group A-4 native valve endocarditis

Eur J Clin Microbiol Infect Dis. 1991 Dec;10(12):1056-7. doi: 10.1007/BF01984928.


A patient with endocarditis caused by Corynebacterium CDC Group A-4 is described. This is the first case in the literature of endocarditis caused by this bacteria, and is unique in that the patient was immune competent and the infection occurred on a native valve. This case illustrates that corynebacteria cannot be considered a contaminant and that the exact pathogen should be identified.
