Catheter urine: >100 million CFU/L E. coli – Shipped on February 10, 2020 FINAL RESULTS
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
- Escherichia coli remains the most common and important pathogen from urine cultures in all populations.
- 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.
