Figure 1. Ribotyping profiles of the two ceftriaxone-resistant Salmonella isolates generated by digestion of chromosomal DNA with SphI and PstI (lanes 1 and 2) or EcoRI (lanes 3 and 4). Lanes 1 and 3, isolate ST275/00; lanes 2 and 4, isolate ST595/00; lane M, 1-kb DNA ladder (Promega Corp., Madison, WI).
