FIG. 1.

(a) PFGE patterns for four isolates (lanes 1 to 4, respectively) found in one stool sample of a patient with acute Campylobacter infection. In lane 1, a 409-kb band was replaced by a 420-kb band. (b) Four isolates (lanes 1 to 4, respectively) from one stool sample showing two different PFGE patterns. The pattern for the first isolate differed from those for the other isolates by seven bands (when the band at 406 kb is considered a double band, as determined by densitometry). (c) ERIC-PCR patterns for four isolates (lanes 1 to 4, respectively) found in one stool sample. The pattern for one isolate (lane 1) differed from the patterns for the other three isolates, which showed no significant differences. Lanes M, molecular size markers.
