M194-1

Catheter urine: >100 million CFU/L E. coli  – Shipped on February 10, 2020 FINAL RESULTS

HISTORY

A simulated in and out catheter urine sample collected from a 51 year old quadriplegic with a fever was sent to category A and C laboratories.
Participants were expected to isolate and identify Escherichia coli and report susceptibilities.

MAIN EDUCATIONAL POINTS from M194-1

  1. Escherichia coli remains the most common and important pathogen from urine cultures in all populations.
  2. Laboratories are reminded that cefazolin should be reported as the first-generation cephalosporin against Enterobacteriales.
    Cephalothin is no longer recommended as a surrogate for other first-generation cephalosporins and should not be reported.
