Throat: No group A, C, G beta hemolytic Streptococcus, no Arcanobacterium haemolyticum – Shipped May 13, 2019 –
A simulated throat swab sample collected from 5 year old with sore throat was sent to category A and C laboratories.
Participants were expected to report the sample as negative for group A, C, G Streptococcus and Arcanobacterium haemolyticum.
MAIN EDUCATIONAL POINTS from M191-1
- Moraxella catarrhalis and Staphylococcus aureus are part of the commensal respiratory flora. Therefore, reporting these organisms from throat swabs may be clinically misleading resulting in unnecessary treatment.
- Negative reports from throat swab should always be pathogen specific (i.e. No Group A, C or G streptococci isolated).
