Figure 3. A typical pulsed-field gel electrophoresis analysis of selected isolates of A. baumannii restricted with ApaI. Lane 1 shows λ ladder used as molecular size marker. Lanes 11–13 are of strains not included in the trial. The gel shows 6 different clones of A. baumannii: 5 isolates belong to clone A and that 2 belong to clone B (the two dominant clones). Single isolates belonging to clones C, D, E, and F can be seen.
