Actinomycetaceae/isolation & purification* Actinomycetales Infections/complications* Adult; Exanthema/microbiology* Humans Arcanobacterium haemolyticum was found in 1.4% and beta-haemolytic streptococci in 23% of throat cultures from army conscripts with sore throat (n = 498). 38% of the beta-haemolytic streptococci were of group A. Patients culture-positive for A. haemolyticum or beta-haemolytic streptococci had pharyngeal exudate, cervical lymphadenopathy and ear ache significantly more often--but cough less often--than culture-negative patients. Arcanobacterium haemolyticum was first described by MacLean et al. in 1946 ( 26) as a pathogen in cases of exudative pharyngitis and soft-tissue infections. In 1982 the previously named Corynebacterium haemolyticum was included in a new genus to reflect major differences in cell wall components and chemotaxonomic characters, the genus Arcanobacterium haemolyticum, formerly known as Corynebacterium hæmolyticum, is a species of bacteria classified as a gram-positive bacillus.

Fever, pharyngeal exudate, lymphadenopathy, rash, and pruritus are common, but palatal petechiae and strawberry tongue are absent. This report describes a case of chorioamnionitis caused by Arcanobacterium haemolyticum, an unusual organism associated with this infection, described mostly in association with infective pharyngitis rarely with bacteremia and soft tissue infections. Arcanobacterium hemolyticum infections are a common cause of pharyngitis and rash in the 10- to 30-year-old age group.
