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 Arcanobacterium haemolyticum. Gram-stain: Negative = 0, Positive = 1, Indeterminate = 2: Found in human microbiome: Microbes that live anywhere in the human body A.haemolyticumwas identified by typical colony morphology, Gram stain, catalase reaction (negative), and carbohydrate fermentation tests (glucose, lactose, sucrose, mannitol, and maltose) and reverse CAMP test. test for identification of Arcanobacterium haemolyti-cum.

[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. haemolyticum diversity in this region. The most significant variable in the present study incubation time 2020-11-21 2011-01-21 The Gram stain shows 3+ thin, gram-positive rods that have filaments. The culture plates were examined the next day and revealed nonhemolytic, pinpoint, transparent colonies.

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 humans and farm animal; occasionally, it causes pharyngeal or skin lesions. The U.S. Department of Energy's Office of Scientific and Technical Information Arcanobacterium are anaerobic, non-motile, nonspore forming, gram-positive, genus Arcanobacterium as Arcanobacterium bernardiae.146 On Gram staining, valve infections (e.g., Arcanobacterium [Corynebacterium] haemolyticum in a  Gram stain and culture of fluid aspirated from the pleural cavity is indicated in patients for whom a diagnosis of infection is considered.
