Notes from the Field: Recurrence of a Multistate Outbreak of Salmonella Enteritidis Infections Linked to Contact with Guinea Pigs a?? Eight States, 2015a??2017

摘要

In December 2017, the Colorado Department of Public Health and Environment reported two human Salmonella Enteritidis infections in persons with exposure to pet guinea pigs. The guinea pigs had been purchased from two separate pet stores, belonging to a single chain, and supplied by a common distributor located in California. Clinical isolates were indistinguishable by pulsed-field gel electrophoresis (PFGE), suggesting the infections were related. This PFGE pattern was previously seen in a 2010 multistate outbreak linked to contact with pet guinea pigs (1). An investigation was initiated to determine the number of patients affected and to identify the source of human illnesses.
