Sucrose-fermenting Salmonella Typhimurium N23-2364: a challenge for the diagnostic laboratory.

We describe a case of Salmonella infection caused by a sucrose-fermenting Salmonella enterica Typhimurium sequence type 12 which acquired transposon CTnscr94 carrying the sucrose operon scrKYABR. Sucrose-fermenting Salmonella are particularly challenging for culture-based detection and may lead to failure to detect Salmonella in clinical samples.
