M134-5

Broncoalveolar lavage (BAL): Rhodococcus equi  – Shipped February 2014

HISTORY

The challenge was sent to category A laboratories. The sample was a simulated bronchoalveolar lavage obtained from a 38 year old HIV+ patient with pneumonia.

Laboratories were expected to isolate, identify, and report Rhodococcus equi. This is the first time CMPT has sent this organism in a PT challenge.

MAIN EDUCATIONAL POINTS from M134-5

  1. Rhodococcus equi is of clinical importance, especially in the immunocompromised host, due to the potential for serious complications and the difficulty in treating patients with Rhodococcus infection.
  2. It is crucial to differentiate Rhodococcus equi from Corynebacterium species, and avoid calling it a contaminant.
