Corynebacterium striatum is an emerging nosocomial pathogen, capable of causing a variety of infections in immunocompromised and hospitalized patients. ; Case Presentation: 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 the Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS), were key to implicate this commensal bacterium as a cause of infection.

Unlabelled: The bacterium is an opportunistic pathogen that can cause lung, skin, wound, joint, urinary tract, and eye infections. While is known to exhibit a robust competitive response toward other bacterial species, this bacterium is frequently identified in polymicrobial infections where multiple species survive. For example, in prosthetic joint infections, can be identified along with other pathogenic bacteria including , , and .

Article Synopsis
- - All 11 patients with bacteremia were treated with daptomycin and initially responded well, showing susceptibility to the drug.
- - During treatment, daptomycin nonsusceptibility developed in 36% of the patients.
- - Clinical failure occurred in 45% of the patients, highlighting significant challenges in effective treatment.

The bacterium is an opportunistic pathogen that can cause lung, skin, wound, joint, urinary tract, and eye infections. While is known to exhibit a robust competitive response towards other bacterial species, this bacterium is frequently identified in polymicrobial infections where multiple species survive. For example, in prosthetic joint infections (PJIs), can be identified along with other pathogenic bacteria including and Here we have explored the survival and behavior of such microbes and find that readily survives culturing with while other tested species do not.
