M173-2

Stool: Salmonella enterica serotype Enteritidis  – Shipped November 06, 2017

HISTORY

A simulated stool collected from a 60 year-old female patient returning from Bangladesh with treatment failure, was sent to category A and B laboratories. The physician requested susceptibility testing.

Participants were expected to identify Salmonella enterica serotype Enteritidis and report susceptibility results.

MAIN EDUCATIONAL POINTS from M173-2

  1. Isolation and identification of Salmonella spp. from stool is an important task for all laboratories performing stool bacterial culture.
  2. Susceptibility testing of Salmonella spp. is not routinely performed from stool isolates, but is important in extraintestinal isolates, neonates and other immunocompromised patients, and in cases of treatment failure. When tested, only ampicillin, trimethoprim-sulfamethoxazole, and ciprofloxacin should be reported routinely.
