Structure of Salmonella genomic island 1 (SGI1). The SGI1 region of serovar Typhimurium DT104 (GenBank accession no. AF261825) is drawn to scale with In104 above. Different discrete segments are represented by open boxes and lines of different thicknesses. Vertical bars indicate the IR bounding In104. The chromosomal genes thdF and yidY flank SGI1. Fragments amplified by polymerase chain reaction are shown as thin lines with the primer pairs indicated. Sequences of primers have been previously d

Fragments amplified by polymerase chain reaction are shown as thin lines with the primer pairs indicated. Sequences of primers have been previously described (7). Arrows indicate the position and orientation of genes and open reading frames. The positions of XbaI sites (×) are indicated with the fragment sizes shown.
