摘要:Arcanobacterium haemolyticum has been described as a rare etiologic agent in acute pharingotonsilitis in pediatric and young population.Four strains of A. haemolyticum were isolated from throat swabs of 3584 patients (10-26 years ) with acute pharingitis. The samples, collected in January 1997-January 2001, were plated on Mueller-Hinton agar with 10 % sheep blood and incubated 24-48 hours at 37 °C. In three cases A.haemolyticum was the only one etiologic bacterial agent and in the forth case association of A.haemolyticum with S.aureus was present. The identification of A.haemolyticum strains was based on cells and colonies’ morphology, cultural and biochemical characters
