Corynebacterium (/ k ɔː ˈ r aɪ n ə b æ k ˌ t ɪər i ə m,-ˈ r ɪ n-/) 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").
The primary value of Loeffler medium is in the growth and morphological characterization of members of the genus Corynebacterium. This formulation enhances the formation of metachromatic granules within the cells of the organisms. Due to its serum content, Loeffler medium can be used for the determination of proteolytic activities of ...
Trichobacteriosis axillaris is a superficial bacterial colonization of the hair shafts in sweat gland–bearing areas, such as the armpits and the groin. It is a trivial disease of worldwide occurrence that is believed to be caused by the genus Corynebacteria.

Corynebacterium diphtheriae [a] is a Gram-positive pathogenic bacterium that causes diphtheria. [2] It is also known as the Klebs–Löffler bacillus because it was discovered in 1884 by German bacteriologists Edwin Klebs (1834–1912) and Friedrich Löffler (1852–1915). [ 3 ]
A corynebacteriophage (or just corynephage) is a DNA-containing bacteriophage specific for bacteria of genus Corynebacterium as its host. [1] Corynebacterium diphtheriae virus [2] strain Corynebacterium diphtheriae phage [2] (aka Corynephage β [3] or just β-phage [4] [5]) introduces toxigenicity into strains of Corynebacterium diphtheriae as it encodes diphtheria toxin, [6] [7] [8] [5] [4 ...
Rhodococcus fascians (known as Corynebacterium fascians until 1984) is a Gram positive bacterial phytopathogen that causes leafy gall disease. [1] R. fascians is the only phytopathogenic member of the genus Rhodococcus ; its host range includes both dicotyledonous and monocotyledonous hosts.
Diphtheria toxin is an exotoxin secreted mainly by Corynebacterium diphtheriae but also by Corynebacterium ulcerans and Corynebacterium pseudotuberculosis, the pathogenic bacterium that causes diphtheria. The toxin gene is encoded by a prophage [annotation 1] called corynephage β.
