Corynebacterium
[ko-ri″ne-bak-tēr´e-um] a genus of gram-positive, nonmotile, straight to slightly curved rod-shaped bacteria. It includes both pathogenic and nonpathogenic organisms, which are widely distributed in nature. Species include
C. ac´nes, found in
acne lesions;
C. diphthe´riae, the etiologic agent of
diphtheria;
C. haemoly´ticum, found in
pharyngitis and skin ulcers;
C. minutis´simum, the causative agent of
erythrasma;
C. pseudodiphtheri´ticum, a nonpathogenic inhabitant of the upper respiratory tract;
C. te´nuis, the causative agent of
trichomycosis axillaris;
C. ul´cerans, which causes nasopharyngeal infections; and
C. xero´sis, an opportunistic pathogen found on the skin and mucous membranes and in the conjunctival sac.

Corynebacterium
(kŏ-rī'nē-bak-tēr'ē-ŭm), A genus of nonmotile (except for some plant pathogens), aerobic to anaerobic bacteria (family Corynebacteriaceae) containing irregularly staining, gram-positive, straight to slightly curved, often club-shaped rods that, as a result of snapping division, may show a picket fence arrangement. These organisms are widely distributed in nature. The best known species are parasites and pathogens of humans and domestic animals. The type species is Corynebacterium diphtheriae.
[G. coryne, a club, + bacterium, a small rod]
