title: Human infections with Actinomyces pyogenes (Corynebacterium pyogenes).
abstract: Actinomyces pyogenes (Corynebacterium pyogenes), a well-known pathogen in many animals, was isolated from 11 Danish patients since 1968. Bacteriologic characteristics and clinical pictures of the patients are described. Ability to hydrolyze gelatine, to produce beta-glucuronidase, to reach with antisera against group-G streptococci, and to produce acid from xylose differentiates A. pyogenes from Arcanobacterium haemolyticum, with which it has at times been confused. Actinomyces pyogenes is an established, but often misrecognized, human pathogen that should be better known to clinical microbiologists.
