Swine Salmonella isolates (n = 674) from various locations throughout the United States and Canada were analyzed via pulsed-field gel electrophoresis (PFGE) with XbaI. PFGE subtypes were analyzed by cluster analysis and compared to conventional serotyping results. The analysis showed a correlation of serotype to PFGE subtype. In addition, conserved fragments were identified within the restriction patterns that were unique to each serotype. PFGE using XbaI restriction provided a possible alternative method for screening and identifying swine Salmonella serotypes.
