“Background Protein Tyrosine Kinase inhibitor Arcanobacterium haemolyticum, a Gram positive, pleomorphic rod, causes wound infections and pharyngitis and can occasionally cause more severe invasive diseases such as endocarditis, meningitis, septic AP26113 purchase arthritis, pneumonia and osteomyelitis in humans [1]. There is strong epidemiologic evidence for A. haemolyticum being the only or primary isolate from throat specimens of some humans with pharyngitis [1–4] and these data suggest that the number of cases per year of A. haemolyticum-mediated pharyngitis is ~240,000-480,000 with 0.5-1 million lost work days in the United States. The organism, previously in the Corynebacterium genus, was classified as the first member of the genus Arcanobacterium [5]. The other members of the genus are uncommonly isolated and remain largely uncharacterized, with the exception of Trueperella (Arcanobacterium) pyogenes, which is an important opportunistic livestock pathogen [6]. Little is known about A.
