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.

(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.
