Figure 2. Repetitive-element sequence–based polymerase chain reaction
analysis of genomic DNA from various Escherichia coli strains using
REP (A) and ERIC (B) primers. Lanes 1 and 2, O153:H7 DNA (rabbit isolates
02-3446 and 02-3301, respectively); Lanes 3–5, O153:H- DNA (rabbit isolates
01-3014, 02-3050, and 02-3300); Lanes 6 and 7, O153:H- DNA (human isolates,
ECRC 99-1808 and 99-1818); Lane 8, no DNA; Lanes 9 and 10, O145:H7 DNA
(rabbit isolates 02-3448 and 02-3205); Lanes 11–13, O145:H- DNA (rabbit
isolates 02-3750, 02-3282, and 02-3055); Lane 14, O145:H- DNA (human isolate,
ECRC 95.1167); Lane 15, O145:H- DNA (bovine isolate, ECRC 95.0187); Lane
16, E. coli isolate of unknown O serotype (03-192) from DB rabbit
02-177; M, 1-kb plus ladder.
