38% of the beta-haemolytic streptococci 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. Listeria-Zym is a commercial kit designed to identifyListeria spp. within 4 h. Its ability to identify two clinically important aerobic catalasenegative, gram-positive rods,Arcanobacterium haemolyticum andActinomyces pyogenes, was evaluated.

Arcanobacterium haemolyticum, formerly known as Corynebacterium hæmolyticum, is a species of bacteria classified as a gram-positive bacillus. It is catalase -negative, aerobic, beta-hemolytic, and not motile. It has been known to cause head and neck infections, pharyngitis, and sinusitis (Arcanobacterium haemolyticum infections). 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.

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 Alpha-mannosidase: a rapid test for identification of Arcanobacterium haemolyticum.
