Arcanobacterium

(ar-kā'nō-bac-tēr'ē-um),
A genus of nonmotile, facultatively anaerobic bacteria containing gram-positive slender irregular rods, sometimes showing clubbed ends that may be in "V" formation with no filaments. These microorganisms are obligate parasites of the pharynx in farm animals and humans. AArcanobacterium haemolyticum occasionally causes lesions of the pharynx or skin.

Arcanobacterium

/Ar·ca·no·bac·te·ri·um/ (ahr-ka″no-bak-tēr´e-um) 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.

A genus of nonmotile, facultatively anaerobic bacteria containing gram-positive slender irregular rods, sometimes showing clubbed ends. These organisms are obligate parasites of the pharynx in farm animals and humans, occasionally causing lesions on the pharynx or skin. The type species is A. haemolyticum.

Arcanobacterium

a genus of pleomorphic gram-positive actinomycete bacteria previously grouped in the genus Corynebacterium.

Arcanobacterium hippocoleae
isolated from vaginitis in horses.
Arcanobacterium phocae
isolated from a variety of body systems in seals, but the pathogenic significance is uncertain.
Arcanobacterium pluranimalium
isolated from lung abscesses in deer and liver abscesses, mastitis, endometritis, abortions and endocarditis in cattle.
Arcanobacterium pyogenes
capable of producing suppurative lesions in any organ or tissue in animals. In farm animals, especially ruminants, it is the most common bacteria found in infected wounds and abscesses. An important cause of mastitis in cattle. Previously called Actinomyces pyogenes and Corynebacterium pyogenes.
