Arcanobacterium hemolyticum: identification and susceptibility to nine antimicrobial agents Arcanobacterium hemolyticum is a b-hemolytic Gram-positive,pleomorphic,facultativeanaerobic, non-acid-fast rod that has been implicated as an etiologic agent of non-streptococcal pharyngitis, especiallyinadolescentsandyoungadults,aswell

The strain is of interest because it is an obligate parasite of the pharynx of humans and farm animal; occasionally, it causes pharyngeal or skin lesions. It is a Gram-positive, nonmotile and non-sporulating bacterium. The arcanobacterium haemolyticum, a.haemolyticum, micrograph, microscopic picture. Arcanobacterium haemolyticum micrograph.

The first cases ascribed to this pathogen were described in 1946 and caused ulcerative skin lesions among American soldiers in the Pacific Islands. Today, infections by A. haemolyticum are rare … 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 … Trueperella pyogenes (Arcanobacterium) looks the same like A. haemolyticum in Gram stain and colony morphology, but T pyogenes is slightly larger and with increased hemolysis McConkey no growth BBAØ growth Characteristics.

genome sequence. Information on the name and the taxonomic classification. The rapid alpha-mannosidase test, in conjunction with a Gram stain and catalase and reverse CAMP tests, was useful in identification of A. haemolyticum and in differentiation of A. haemolyticum from A. pyogenes and Corynebacterium spp. PMCID: PMC263142 PMID: 7710479 [Indexed for MEDLINE] Publication Types: Comparative Study; MeSH terms 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. A genus of facultatively anaerobic, gram-positive bacteria in the family ACTINOMYCETACEAE, order ACTINOMYCETALES. They are obligate parasites of the PHARYNX in humans and farm animals.
