Laboratory-Acquired Infection with Salmonella enterica Serovar Typhimurium Exposed by Whole-Genome Sequencing.

Despite advances in laboratory design, professional training, and workplace biosafety guidelines, laboratory-acquired infections continue to occur. Effective tools are required to investigate cases and prevent future illness. Here, we demonstrate the value of whole-genome sequencing as a tool for the identification and source attribution of laboratory-acquired salmonellosis.
