Throat: Arcanobacterium haemolyticum – Shipped August 2012
The challenge was sent to category A, B, and C laboratories. The sample was a simulated throat swab obtained from a 15 year old high school student with recurrent pharyngitis. The history for this sample stated that the physician required culture.
Laboratories were expected to isolate, identify, and report Arcanobacterium haemolyticum.
MAIN EDUCATIONAL POINTS from M122-1
- Arcanobacterium haemolyticum is a cause of pharyngitis and should not be ignored in throat cultures, particularly in situations where recurrent pharyngitis is noted, and the patient is adolescent or young adult.
- For those labs where throat culture is not routinely performed and the presence of group A streptococcus is tested by alternate methods, culture for other organisms should be available at request of physician.
