M163-1

Throat: Arcanobacterium haemolyticum  – Shipped November 07, 2016

HISTORY

A simulated throat sample collected from a 14 year old patient with sore throat, rash, and a history of treatment failure was sent to category A, B, and C laboratories.
Participants were expected to isolate, identify, and report Arcanobacterium haemolyticum.

MAIN EDUCATIONAL POINTS from M163-1

  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 accompanied rash, in treatment failure and the patient is adolescent or 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.
