title: Bacteriological characteristics of Arcanobacterium haemolyticum isolated from seven patients with skin and soft-tissue infections.
abstract: Bacteriological examinations were conducted for seven Arcanobacterium haemolyticum strains isolated from elderly patients with skin and soft-tissue infections, such as cellulitis and skin ulcers. Streptococcus dysgalactiae or Gram-positive cocci were isolated together with A. haemolyticum from all patients. The strains were identified as A. haemolyticum based on their being catalase negative, reverse Christie, Atkins and Munch-Petersen (CAMP) positive and phospholipase D gene positive in respective tests. Moreover, API Coryne and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry confirmed the identification of A. haemolyticum. All strains showed good susceptibility to minocycline, vancomycin and β-lactam antibiotics, but several strains were resistant to gentamicin and levofloxacin.
