title: Actinomyces pyogenes septic arthritis in a diabetic farmer.
abstract: We report a case of septic arthritis and osteomyelitis of the left ankle due to Actinomyces pyogenes in a diabetic farmer. Few confirmed human cases of A. pyogenes infection have been reported, partly because of inadequate identification of this bacterium. Bacteriological characteristics of the organism, which resembles Arcanobacterium haemolyticum, are described with a review of previous case reports.
