title: Comparative studies on Actinomyces pyogenes and Arcanobacterium haemolyticum.
abstract: Actinomyces pyogenes and Arcanobacterium haemolyticum were further characterized. A. haemolyticum, in contrast to A. pyogenes, gave synergistic hemolytic reactions with streptococci of serological group B and inhibited staphylococcal beta-hemolysis. A. pyogenes and A. haemolyticum had a number of common, as well as distinctly different enzymatic properties, useful for their characterization. Extracts from A. pyogenes reacted with antiserum against streptococci of serological group G in contrast to those from A. haemolyticum.
