M193-1

Throat: Arcanobacterium haemolyticum – Shipped November 4, 2019 FINAL RESULT

HISTORY

A simulated throat swab collected from a 13 year old female with a rash and sore throat was sent to category A and C laboratories.
Participants were expected to isolate and identify Arcanobacterium haemolyticum.

MAIN EDUCATIONAL POINTS from M193-1

  1. Arcanobacterium haemolyticum has been 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 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 performed when clinically indicated.
