Corynebacterium striatum: An emerging nosocomial skin and soft-tissue pathogen

ABSTRACT

The genus Corynebacterium is composed of Gram-positive, aerobic, non-motile, non-spore-forming bacilli that are widely distributed throughout the environment. They are usually found as commensals on the skin and are often considered as mere contaminants when isolated from clinical samples. We describe a patient with skin and soft-tissue infections due to Corynebacterium striatum following exploratory laparotomy identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry. The clinical importance and pathogenic potential of Corynebacterium species, especially C. striatum, cannot be underestimated. This report is a reminder to physicians of the possible pathogenicity of non-diphtherial Corynebacteria.
