Genetic relatedness, the presence of PMQRs and chromosomal mutations and MIC values of meropenem and ciprofloxacin in NDM-positive (a) E. coli and (b) K. pneumoniae isolates. Analysis of PFGE of XbaI digestion pattern based on Dice’s similarity co-efficient and UPGMA (the position tolerance and optimization were set at 1.5 and 1.5% respectively). More than 95% similarity in PFGE band pattern interpreted as indistinguishable. MEM: meropenem, CIP: ciprofloxacin
