Arcanobacterium (/ ɑːrˈkeɪnoʊbækˌtɪəriəm /) is a genus of bacteria. They are gram-positive, non– acid fast, non motile, 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 (A. haemolyticum) beskrevs för första gången under namnet Corynebacterim haemolyticum av MacLean och medarbetare 1946. Bakterien odlades fram från svalget hos patienter med halsont och från sår. Patienterna bestod av amerikanska soldater och infödda öbor i Stilla havet.

Arcanobacterium haemolyticum colony morphology

The strains were susceptible to penicillins, cephalosporins, erytromycin and resistant to trimethoprim-sulphamethoxazole. Pharyngeal injection in 89.47% and exanthem in 78.90% were the most common signs present to the patients.

One, the smooth type, grew as smooth, beta-hemolytic colonies and was beta-glucuronidase negative but often fermented sucrose and/or trehalose, while the other, the rough type, grew as rough colonies and was 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. Arcanobacterium may colonize mucous membranes from humans and farm animals.

This bacterial species is also a rare pathogen of animals.

Arcanobacterium haemolyticum. Colonial morphology: Describe the colony morphology and partial acid fastness of Rhodococcus equi. Colonial morphology

Colony morphology and the degree of matic wound healing. hemolysis differ considerably with the type of blood and media used [15]. Hemolysis is more pronounced on The association of Arcanobacterium haemolyticum with human or rabbit blood than on sheep blood agar.
