M151-3

Stool: No Salmonella, Shigella, Campylobacter, Yersinia, Aeromonas, Plesiomonas, Vibrio species, E. coli O157:H7, or Edwardsiella tarda (NSSCYAPVEE) isolated  – Shipped May 2015

HISTORY

A simulated stool collected from a 42 year old female patient returning from Spain was sent to category A and B laboratories. Participants were expected to report the absence of specific enteric pathogens in the stool sample.

MAIN EDUCATIONAL POINTS from M151-3

  1. When clinicians send stool cultures it is usually to determine if an enteric pathogen is present that might account for a patient’s symptoms. It is therefore important to indicate if enteric pathogens are present or not.
  2. Stool cultures are directed to detect specific pathogens and the menu of organisms that are routinely included varies, as a result of epidemiological or other considerations, and so it is important to indicate which organisms have been sought.
