Figure. Pulsed-field gel electrophoresis (PFGE) XbaI (A) and BlnI (B) patterns of 9 ciprofloxacin-resistant Salmonella enterica serotype Typhi isolates detected in the National Antimicrobial Resistance Monitoring System, 1999–2008. PFGE pattern similarity was assessed by cluster analysis (Dice, UPGMA [unweighted pair group method using arithmetic average]) and band-matching applications of BioNumerics software (Applied Maths, Sint-Martens-Latem, Belgium) and confirmed by visual comparison. PulseNet only considers band markings found within the scale of the global standard, which are all bands between 20.5 kb and 1,135 kb. The cluster parameters are Dice coefficient and UPGMA with the tolerance of band position of 1.5% and optimization of 1.5%.
