Corynebacterium striatum: An emerging nosocomial pathogen.

Corynebacterium striatum is an emerging nosocomial pathogen capable of causing a variety of infections in immunocompromised and hospitalized patients. We describe three cases of infection by C. striatum that were initially considered as contamination. Clinical suspicion in the wake of predisposing factors and accurate identification, using Matrix Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) were key to implicate this commensal bacteria as a cause of infection.
