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").
Corynebacterium diphtheriae Gram stain. The purple colour of the bacterium is indicative of the thin peptidoglycan wall surrounding the bacterium. The 'club-like' structure can be observed. This an example of a Coryneform bacterium. Corynebacterium striatum is a gram-positive bacterium. It has a thin external peptidoglycan cell wall structure.
Appearance of C. xerosis colonies on blood agar. Corynebacterium xerosis is a gram-positive, rod-shaped bacterium in the genus Corynebacterium.Although it is frequently a harmless commensal organism living on the skin and in the mucous membranes, C. xerosis is also a clinically relevant opportunistic pathogen that has been attributed to many different infections in animals and humans.
Corynebacterium diphtheriae is the bacterium that causes the disease called diphtheria. Bacteriophages introduce a gene into the bacterial cells that makes a strain toxigenic. The strains that are not infected with these viruses are harmless. [5] C. diphtheriae is a rod-shaped, Gram-positive, non spore-forming, and nonmotile bacterium. [17]
A Gram stain of mixed Staphylococcus aureus (S. aureus ATCC 25923, gram-positive cocci, in purple) and Escherichia coli (E. coli ATCC 11775, gram-negative bacilli, in red), the most common Gram stain reference bacteria. Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups ...
Corynebacterium amycolatum is a gram-positive, non-spore-forming, aerobic or facultatively anaerobic bacillus capable of fermentation [1] with propionic acid as the major end product of its glucose metabolism. One of its best known relatives is Corynebacterium diphtheriae, the causative agent of diphtheria.
Arcanobacterium haemolyticum is a species of bacteria classified as a gram-positive bacillus. It is catalase -negative, facultative anaerobic , beta-hemolytic , and not motile . [ 1 ] It has been known to cause head and neck infections, pharyngitis , and sinusitis ( Arcanobacterium haemolyticum infections ).
Corynebacterium matruchotii are Gram positive bacilli with long filaments and short, thick terminal ends. C. matruchotii is a bacterium of significance within the oral cavity and comprises the central filament of "corn-cob formations" (formations in which Streptococcus sanguinis bacteria bind to and surround C. matruchotii to create a corn-cob ...
