(2004). rpoB gene sequencing for identification of Corynebacterium species. (2009). Synergistic and antagonistic hemolytic activities of bacteria of genus Arcanobacterium and CAMP-like hemolysis of Arcanobacterium phocae and Arcanobacterium haemolyticum with Psychrobacter phenylpyruvicus.

Rhodococcus equi and Arcanobacterium haemolyticum, formerly classified in the genus Corynebacterium, are members of the loosely defined taxon "coryneform" bacteria. Although they are the etiologic agents of distinct human infections, both organisms are frequently overlooked, which results in missed or delayed diagnoses. An Arcanobacterium haemolyticum strain isolated from a postcastrational lesion of a horse was identified phenotypically and genotypically. The latter was performed by sequencing the 16S-23S rDNA intergenic spacer region (ISR), by amplification of the gene encoding A. haemolyticum phospholipase D, by amplification of A. haemolyticum specific parts of ISR-23S rDNA and by amplification of the Arcanobacterium haemolyticum was first described by MacLean et al. in 1946 (26) as a pathogen in cases of exudative pharyngitis and soft-tissue infections.

Arcanobacterium haemolyticum identification

2002-12-01 · Arcanobacterium hemolyticum is a β-hemolytic Gram-positive, pleomorphic, facultative anaerobic, non-acid-fast rod that has been implicated as an etiologic agent of non-streptococcal pharyngitis, especially in adolescents and young adults, as well as a cause of skin and wound infections, osteomyelitis, sepsis, and central nervous system infections. Arcanobacterium hemolyticum, a gram-positive pathogen that may cause pharyngitis in adolescents, can be isolated from throat cultures after prolonged incubation (> 72 hrs), and whose colonies in conjunction with a Gram stain and catalase and reverse CAMPtests, was useful in identification ofA. haemolyticum andin differentiation ofA. haemolyticum fromA.pyogenes andCorynebacterium spp. Arcanobacterium haemolyticum (formerly Corynebacterium haemolyticum [3]) is an aerobic, catalase-negative, gram-posi- 2017-04-24 · The bacterium now named Arcanobacterium haemolyticum was first described in 1946 as the pathogenic agent causing pharyngitis and cutaneous infections among US service members and indigenous peoples En général, Arcanobacterium haemolyticum est très sensible aux antibiotiques.

in 1946 ( 26) as a pathogen in cases of exudative pharyngitis and soft-tissue infections. In 1982 the previously named Corynebacterium haemolyticum was included in a new genus to reflect major differences in cell wall components and chemotaxonomic characters, the genus Arcanobacterium ( 10 ). Arcanobacterium haemolyticum, formerly known as Corynebacterium haemolyticum, is a Gram-positive bacillus that most often infects adolescents and young adults, and may result in a syndrome of pharyngitis and a scarlatiniform exanthem. 36 The pharyngitis in these patients is usually severe (occasionally mistaken for diphtheria), and the exanthem may also occasionally mimic toxic shock syndrome, measles, urticaria, or erythema multiforme. 37,38 in conjunction with a Gram stain and catalase and reverse CAMPtests, was useful in identification ofA.
