FIG. 3.

Single-cycler dendrogram (cycler A) of composite (ERIC2 plus BOXA1R) fingerprints for 70 isolates of S. enterica. The individual primer fingerprints as shown in Fig. 1 and 2 were combined head-to-toe to create the virtual composite fingerprints shown here, which were analyzed in the same manner as the individual fingerprints. Methods and labels are as described in the legend to Fig. 1. Gel strips as shown are computer reconstructions and hence underestimate the clarity of the actual gel images. See reference 16 for examples of primary rep-PCR fingerprints.
