Organism Spotlight: Clinically Significant Corynebacteria—More Than Diphtheroids
Continuing Education Credits
Objectives
- Describe the typical microscopic and culture characteristics of Corynebacterium species.

- Recognize findings that suggest a Corynebacterium isolate represents true infection rather than contamination.
- Explain special laboratory considerations associated with C. diphtheriae and diphtheria toxin testing.
- Recognize important identification and antimicrobial resistance considerations among nondiphtheriae corynebacteria.
