Pulsed-field gel electrophoresis (PFGE) profiles of representative S . Typhimurium, PT Untypable, ASSuT isolates digested with BlnI. Lane 1, H9812 (S. Braenderup control), lane 2, 03–0407, lane 3, 05–0802, lane 4, 05–0900, lane 5, H9812 (S. Braenderup control), lane 6, 05–0902, lane 7, 07–0028, lane 8, 07–0060, lane 9, 07–0146, lane 10, H9812 (S. Braenderup control), lane 11, 07–0174, lane 12, 07–0200, lane 13, 07–0201, lane 14, 07–0204, lane 15, H9812 (S. Braenderup control). PFGE with both XbaI and BlnI was performed on all isolates with same phenotype as isolate 07–0146. Digestion with BlnI proved more discriminatory showing 07–0146 and 07–0237 to be indistinguishable from each other and different from other isolates in our collection.
