M124-3

Wound (breast): Staphylococcus lugdunensis – Shipped February 2013

HISTORY

The challenge was sent to category A and B laboratories. The sample was a simulated breast wound obtained from a 45 year old female patient.

Participants were expected to isolate and identify Staphylococcus lugdunensis. Laboratories were also expected to report antimicrobial susceptibilities and correlate the results with the companion Gram challenge (G124).

MAIN EDUCATIONAL POINTS from M124-3

  1. S. lugdunensis is now recognized as a significant pathogen capable of causing severe wound and abscess infections.
  2. S. lugdunensis is an aggressive pathogen that behaves like S. aureus and should not be ignored as “normal flora”.
