A total of 69 pulsed-field gel electrophoresis (PFGE) types were
identified among 176 Campylobacter jejuni isolates from
Finnish patients. In two geographic areas studied, five predominant
PFGE types comprised over 40% of the isolates. One-third of the
isolates had unique PFGE types. In small outbreaks, identical PFGE
patterns were demonstrated, indicating a common source of infection.
