Arcanobacterium pyogenes

Arcanobacterium a genus of pleomorphic gram-positive actinomycete bacteria previously grouped in the genus
Corynebacterium. a genus of irregular, rod-shaped, non–spore-forming, gram-positive bacteria. A. haemoly´ticus
causes human infection that is manifested in adolescents as pharyngitis and a scarlatiniform rash similar to those of
streptococcal infection.

Arcanobacterium pyogenes (formerly Actinomyces pyogenes) often cause severe clinical mastitis characterized by
thick, purulent secretion. The foul odor sometimes associated with this condition is probably caused by anaerobic
bacteria that are also present but not detected by routine cultural methods.

Arcanobacterium pyogenes is a rare cause of infection in humans, mostly related to living in rural areas and to contacts
with animals. We describe a case of fatal Arcanobacterium pyogenes endocarditis, confirmed by DNA sequencing, in a
patient without typical epidemiological exposure. Table 1 Characteristics of 13 confirmed cases of human infections with
Arcanobacterium pyogenes obtained from sterile sites

Arcanobacterium pyogenes, a commensal on the mucous membranes of many economically important animal species,
is also a pathogen, causing abscesses of the skin, joints, and visceral organs as well as mastitis and abortion.
