Salmonella enterica Serotype Typhi with Nonclassical Quinolone Resistance Phenotype
Figure 2. XbaI pulsed-field gel electrophoresis (PFGE) profiles obtained from 10 Salmonella enterica serotype Typhi isolates belonging to subpopulation B. The dendrograms generated by BioNumerics version 3.5 software (Applied Maths, Sint-Martens-Latem, Belgium) show the results of cluster analysis on the basis of PFGE fingerprinting. Similarity analysis was performed by using the Dice coefficient, and clustering was done by using the unweighted pair-group method with arithmetic averages.
