Reduced Fluoroquinolone Susceptibility in Salmonella enterica Isolates from Travelers, Finland
Figure 1. Ciprofloxacin susceptibility and quinolone resistance in 227 Salmonella enterica isolates collected from travelers returning to Finland from Thailand or Malaysia, 2003–2007. A) Percentage of isolates showing reduced ciprofloxacin susceptibility (black bars, MIC >0.125 µg/mL, p = 0.002). B) Percentage of isolates showing conventional (black bars, MIC of nalidixic acid >32 µg/mL, p = 0.0014) or nonclassical (white bars, MIC of nalidixic acid <32 µg/mL, p = 0.878) quinolone resistance phenotype.
