M211-1

Throat: Arcanobacterium haemolyticum – Shipped May 10, 2021

HISTORY

A simulated throat sample collected from a 14 year old with a sore throat was sent to category A laboratories. Participants were expected to isolate and report Arcanobacterium haemolyticum.

MAIN EDUCATIONAL POINTS from M211-1

  1. Arcanobacterium haemolyticum is associated with pharyngitis and should not be ignored in throat cultures, particularly in situations of recurrent pharyngitis, with or without accompanying rash, in treatment failure, and when the patient is adolescent or a young adult (10-30 years).
  2. For laboratories where a throat culture is not routinely performed and presence of group A Streptococcus is tested by an alternate method, culture for other organisms should be available and performed when clinically indicated.
