Arcanobacterium haemolyticum is an important human and animal pathogen that is gram-positive and a facultative anaerobe (Vu & Rajnik, 2022).

Arcanobacterium haemolyticum
Description and Significance
Arcanobacterium haemolyticum is an important human and animal pathogen that is gram-positive and a facultative anaerobe (Vu & Rajnik, 2022). It appears to be a branching bacillus bacteria (Vu & Rajnik, 2022). From swabs and cultures done from swabs, it seems that even in healthy individuals (both human and animal) Arcanobacterium haemolyticum can be found on the skin and pharynx normally (Vu & Rajnik, 2022). As an obligate parasite, Arcanobacterium haemolyticum has been known to cause pharyngitis and skin lesions on some individuals, particularly adolescents and elderly patients (Vu & Rajnik, 2022), which makes it an important microbe to understand.
Genome Structure
The genome of strain 110108T, which is the type strain of Arcanobacterium haemolyticum, is a circular chromosome that is 1,986,154 bp long. 87.2% of the genome is DNA coding (1,744,192 bp), and the GC content of the genome is 53.13% (1,055,308 bp). The genome of Arcanobacterium haemolyticum codes for a total of 1,885 genes, with 64 of those being RNA genes and the other 1,821 genes being protein encoding genes (Yasawong et al., 2010).
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
