M163-5

Blood: Enterococcus gallinarum  – Shipped November 07, 2016

HISTORY

A simulated Blood Culture sample collected from a 45 year old in ICU with suspected endocarditis was sent to category A laboratories.
Participants were expected to isolate, identify and report Enterococcus gallinarum; laboratories were also expected to perform and report susceptibility testing on this organism.

MAIN EDUCATIONAL POINTS from M163-5

  1. Entercoccus species considered as potential VRE should be differentiated by species and vancomycin MIC to best categorize the isolate for epidemiology and infection control purposes.
  2. These enterococci that are intrinsically resistant to vancomycin at low concentrations are not considered a significant infection control burden.
