Abstract:
We present a case of laboratory-acquired Salmonella Typhi, resulting in hospitalization of a technician. Blood and stool cultures revealed a S. Typhi strain, identical to the strain with which the employee had recently worked, confirmed using core-genome multilocus sequence typing. The incident occurred despite working in a biosafety cabinet.
