Haplotypes are defined in Figure 1. NalS: Nalidixic acid susceptible (MIC<8 µg/mL); NalR: Nalidixic acid resistant (MIC>256 µg/mL); CipS: ciprofloxacin susceptible (MIC<0.125 µg/mL); CipI: ciprofloxacin reduced susceptible (MIC≥0.125 µg/mL); CipR: ciprofloxacin resistant (MIC>1 µg/mL);

*Cip MIC>16 µg/mL.
