2. Figure 1
EcoRI restriction enzyme digests of the ampicillin-resistant trans-conjugants. The sizes in kb of Λ-phage DNA fragments resulting from Hind III digestion are shown to the left of the gel. SeI: trans-conjugant of the S. enteritidis carrying the 34-MDa plasmid (4). SeV: trans-conjugant of the S. enteritidis carrrying the 100-MDa plasmid (4). Sp=S. paratyphi, St=S. typhi (this study).

Genotypic diversity of ampicillin-resistant and -sensitive strains. PFGE chromosomal fingerprints (PFGE type) of ampicillin (AMP)-resistant (R) and -sensitive (S). S. typhi (St) and S. paratyphi B (Sp) strains. Sizes, in kb, of Λ-phage concatamers are indicated to the left of the gel.
