Corynebacterium
Corynebacterium () is a genus of Gram-positive bacteria and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name (coryneform means "club-shaped").

Corynebacterium (von griechisch κορύνη korýnē, deutsch ‚Keule‘) ist eine Gattung aerob bis fakultativ anaerob lebender, grampositiver Bakterien mit hohem GC-Gehalt. Die Vertreter sind zwischen 3 und 5 μm lang, bilden keine Sporen und sind unbeweglich. Corynebakterien gehören in die CMNR-Gruppe, wie auch Mycobakterium, Nocardia und Rhodococcus. Diese Gruppe zeichnet ein hoher G+C Gehalt im Genom aus, sowie Mykolsäuren, Arabinogalactan und Peptidoglycan in ihrer Zellmembran. Die Gattung ist vielfältig; einige Vertreter sind für den Menschen oder Tiere pathogen. Andere sind Saprophyten und leben auf verfaulenden Pflanzenresten. Einige Arten kommen häufig in der Schleimhautflora und auf der Haut des Menschen vor.

Corynebacterium () is a genus of Gram-positive bacteria and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name (coryneform means "club-shaped").
They are widely distributed in nature in the microbiota of animals (including the human microbiota) and are mostly innocuous, most commonly existing in commensal relationships with their hosts. Some, such as C. glutamicum, are commercially and industrially useful. Others can cause human disease, including, most notably, diphtheria, which is caused by C. diphtheriae. Like various species of microbiota (including their relatives in the genera Arcanobacterium and Trueperella), they are usually not pathogenic, but can occasionally capitalize opportunistically on atypical access to tissues (via wounds) or weakened host defenses.
