II. Pathophysiology
- Non-motile, non-spore forming rod-shaped (or pleiomorphic) Bacteria
- Corynebacterium is derived from Greek (Koryne=Club, Bacterion=Little Rod)
- May be aerobic or anaerobic

- Coryneform Bacteria (Diphtheroids)
- Includes multiple genera in addition to Corynebacterium (e.g. Arcanobacterium, Brevibacterium, Microbacterium)
- Colonize human skin as well as soil and water
- Frequently found in contaminated cultures in hospitalized patients
- Community acquired infections
- Nosocomial Infections
- Sites

| Definition (NCI) | A species of aerobic or facultatively anaerobic, Gram-positive, coryneform, pleomorphic bacilli assigned to the phylum Actinobacteria. This species is nonmotile, non-spore forming, catalase positive, urease negative, pyrazinamidase positive, reduces nitrate, ferments glucose and sucrose, non-lipophilic, indole negative, and hydrolyzes gelatin. C. striatum is commensal in the skin and nasal flora and is a pathogen known to cause bacteremia in immunocompromised patients with respiratory infections, skin ulcers, or during surgery. |
