Pulsed-field gel electrophoresis (PFGE) patterns of Salmonella enterica serovar Infantis isolates from clinical, food, and poultry sources isolated in Israel, 1970–2009, showing a high degree of clonality. Isolate number, year of isolation, and source are indicated. Bracket indicates I1 pulsotype pattern. Macrodigestion performed using XbaI restriction enzyme and genetic similarity (in %) was based on dice coefficients. PFGE was conducted according to the standardized Salmonella protocol Centers

Figure 2. Pulsed-field gel electrophoresis (PFGE) patterns of Salmonella enterica serovar Infantis isolates from clinical, food, and poultry sources isolated in Israel, 1970–2009, showing a high degree of clonality. Isolate number, year of isolation, and source are indicated. Bracket indicates I1 pulsotype pattern. Macrodigestion performed using XbaI restriction enzyme and genetic similarity (in %) was based on dice coefficients. PFGE was conducted according to the standardized Salmonella protocol Centers for Disease Prevention and Control PulseNet as described (4) by using S. enterica ser. Braenderup H9812 strain as a molecular size standard. Because of space limitations, only 34/58 pulsotype I1 clones are shown. A complete list is provided in the Appendix Table.
