M144-1

Midstream Urine: >100 x10^6 cfu/L Escherichia coli & Klebsiella pneumoniae  – Shipped February 2015

HISTORY

A simulated midstream urine collected from a 72 year old symptomatic female patient in a nursing home was sent to category A, B, and C laboratories.

Participants were expected to isolate and identify Escherichia coli and Klebsiella pneumoniae. Participants were also expected to report colony count and perform susceptibility testing on both isolates.

MAIN EDUCATIONAL POINTS from M144-1

  1. Isolation of more than one uropathogen at significant concentrations in a symptomatic patient warrants identification and susceptibility testing for both isolates.
  2. Antimicrobial susceptibility testing and reporting of appropriate agents for the clinical setting is important to ensure that such patients get effective treatment for the infection.
