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 Arcanobacterium haemolyticum is a gram-positive, facultative anaerobic, branching bacillus. 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 … 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. Gram-positive bacilli difteroid growth both-aerobic-and-anaerobic 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 2017-04-24 · A haemolyticum is a pleomorphic, facultatively anaerobic, nonmotile, nonsporulating, non–acid-fast, catalase-negative, hemolytic gram-positive rod.

Arcanobacterium (/ ɑːr ˈ k eɪ n oʊ b æ k ˌ t ɪər i ə m /) is a genus of bacteria. They are gram-positive, non–acid fast, nonmotile, facultatively anaerobic, and non–endospore forming. They are widely distributed in nature in the microbiota of animals (including the human microbiota) and are mostly innocuous. Arcanobacterium haemolyticum (ex MacLean et al. 1946) Collins et al. 1983 is the type species of the genus Arcanobacterium, which belongs to the family Actinomycetaceae.

Arcanobacterium haemolyticum ATCC® BAA-1784™*
Bronchial tissue Gram stain showing intrahistiocytic coccobacillary forms of Rhodococcus equi.Original magnification, x 1,000. B.Open lung biopsy showing coalescent microabscesses with numerous histiocytes containing Rhodococcus equi organisms. Gram stain of colony growth. A. haemolyticum are classically associated with causing sore throat, particularly in late teenagers. They can cause enlarged lymph nodes in the neck and rash and therefore mimic Streptococcus pyogenes (Group A Streptococcus) infection. A 4-h alpha-mannosidase test for identification of Arcanobacterium haemolyticum strains (n = 139) and differentiation of A. haemolyticum from Actinomyces pyogenes strains (n = 30) and other gram-positive rods was evaluated. Arcanobacterium haemolyticum on gram stain of growth from throat culture.
demonstrates delicate, curved, gram-positive rods with pointed ends and occasional rudimentary branching. This branching is more pronounced after these organisms have been cultured anaerobically. Arcanobacterium spp. stain unevenly after 48 hours of growth on solid media and also exhibit coccal forms. Gram Stain of Arcanobacterium haemolyticum. Gram Positive with Crystal Violet (Arcanobacterium haemolyticum) Hemolysis of Arcanobacterium haemolyticum.
