However, gram staining revealed that the organism was a gram-positive bacillus, and a reverse Christie, Atkins, Munch-Peterson (CAMP) test showed that the organism inhibited the β-hemolysis of Staphylococcus aureus on sheep blood agar. Biochemical testing identified the organism as A. haemolyticum.
Strain 11018 T (= DSM 20595 = CCM 5947 = ATCC 9345 = NBRC 15585) is the type strain of the spe-cies A. haemolyticum, which is the type species of its genus Arcanobacterium [1]. Arcanobacterium is
1946) Collins et al. 1983 is the type species of the genus Arcanobacterium, which belongs to the family Actinomycetaceae. The strain is of interest because it is an obligate parasite of the pharynx of The bacterium is a gram-positive prokaryote that assumes a 'club-like' morphology, more formally known as a corynebacteria structure. [1] [3] [4] It is non-lipophilic and undergoes aerobic respiration and is also a facultative anaerobe it is catalase negative and oxidase positive glucose and sucrose fermenter. 2016-08-25 selected one strain from each of six DNAtypes which represented79%ofall isolates availableinourA. haemolyti-cumcollection. Therefore, it seemslikely that the relatively small numberofstrains in this studyrepresent agoodcross section ofA.

Gram staining Appendix 1 Properties of an Arcanobacterium haemolyticum strain isolated from a Gram staining is widely used to discriminate bacteria into Gram-positive and Gram-positive rods or cocci as determined by Gram stain.

Arcanobacterium hemolyticum: identification of colonies, Gram stain and biochemical tests, following myces pyogenes and Arcanobacterium haemolyticum.
Arcanobacterium haemolyticum is a catalase negative gram-positive rod, showing narrow zones of beta-haemolysis when cultured on human or rabbit blood agar6, 10. A.haemolyticum was identified by typical colony morphology, Gram stain, catalase reaction (negative), and carbohydrate fermentation tests (glucose, lactose, sucrose, mannitol, and maltose) and reverse CAMP test.
This organism may be part of commensal flora of the respiratory and gastrointestinal tracts. A. haemolyticum is associated with pharyngitis, typically with a rash (erythematous, scarlatiniform, urticarial or morbilliform involving trunk and extremities, sparing face, palms, and soles) in young adults.
