FIG. 2.

A. IS200 profiles of representative multidrug-resistant S. enterica serotype Paratyphi B isolates and comparison strains. B. Dendrogram generated by BioNumerics showing the results of cluster analysis of the 14 XbaI-PFGE patterns observed among 49 S. enterica serotype Paratyphi B isolates typed. Similarity analysis was performed using the Dice coefficient, and clustering was by the unweighted pair group method with arithmetic averages. The different PFGE types and corresponding numbers of isolates are indicated.
