Figure 1. Genetic organization of the antibiotic resistance gene cluster of Salmonella genomic island 1 (SGI1) of Salmonella enterica serovar Typhimurium DT104 and serovar Albany strain 7205.00. DR-L and DR-R are the left and right direct repeats, respectively, bracketing SGI1. Polymerase chain reactions (PCRs) used to assess the genetic organization of the antibiotic resistance genes (PCRs floR, A, B, C, D, E, and F) and the SGI1 junctions to the chromosome (PCRs LJ and RJ for left and right junctions respectively) are indicated. Abbreviations used: S., Salmonella; X, XbaI; H, HindIII; Xh, XhoI; E, EcoRI; orf, open reading frame.
