M214-3

Wound: Streptococcus pyogenes  – Shipped February 07, 2022

HISTORY

A simulated wound swab collected from a 54 year-old female in-patient, with debrided leg wound was sent to category A laboratories. Participants were expected to report Streptococcus pyogenes.

MAIN EDUCATIONAL POINTS from M214-3

  1. The most common source of S. pyogenes is the upper respiratory tract (i.e., streptococcal pharyngitis). However, this species can also cause invasive infections as identified in this challenge of a debrided wound.
  2. Rapid identification and reporting of the isolate in this debrided wound has important implications for antimicrobial treatment and resolution of invasive S. pyogenes infections.
