PFGE patterns of XbaI-cleaved genomic DNA of S. sonnei isolates. Lanes: M, lambda phage molecular weight ladder; 1, outbreak-related isolate from 1998; 2, sporadic isolate from 1998; 3, outbreak-related isolate from 1998; 4, outbreak-related isolate from 1999; 5, sporadic isolate from 1998; 6, sporadic isolate from 1998; 7, outbreak-related isolate from 2000; 8, 91NH14 from 1991. The PFGE patterns of lanes 1, 3, 4, 5, and 8 were identical and were classified pattern A. The PFGE patterns of lanes 2 and 6 were classified patterns B and C, respectively. The pattern of the 20 outbreak-related isolates from 2000 (lane 7) was classified pattern D.
