M114-4

Central line: Corynebacterium striatum (companion to G114) – Shipped February 2012

HISTORY

A sample simulating a central line obtained from a 50 year old male with leukemia was sent to category A laboratories.

Participants were expected to isolate and report Corynebacterium striatum. Laboratories were asked to report susceptibility to vancomycin and penicillin and comment on any other antimicrobial agent that they would normally report

MAIN EDUCATIONAL POINTS from M114-4

  1. Corynebacterium striatum is an emerging pathogen, particularly in immunocompromised patients or those with a prosthetic device in place including pacemaker leads, joints or heart valves.
  2. Because Corynebacterium striatum is often multi-drug resistant, antibiotic susceptibility testing should be done on isolates recovered from central line sites, line tips, and blood or other invasive sites/sources.
