Figure 2

Dendrogram showing the clonal relationships among 36 isolates of Salmonella enterica collected from travelers returning to Finland from Thailand or Malaysia, 2003–2007. These isolates showed the nonclassical quinolone resistance phenotype (i.e., reduced susceptibility to ciprofloxacin [MIC >0.125 µg/mL] and susceptibility or low-level resistance to nalidixic acid [MIC <32 µg/mL]). No., number of Salmonella isolates belonging to a certain pulsed-field gel electrophoresis (PFGE) pattern.
