^aThe nomenclature of the Salmonella PFGE patterns used by the Laboratory of Gastrointestinal Pathogens is consistent with Salm-gene/Pulse-Net. Uppercase letters are based on the serotype examined and the macrorestriction enzyme used, followed by a period and then an arbitrary number (usually based on the order in which the patterns are identified).
