Dendrogram of PFGE profiles of XbaI-digested DNA restriction fragments from 68 carbapenem-resistant Klebsiella pneumoniae ST11 isolates. The UPGMA algorithm was performed to conduct dendrogram based on the Dice similarity coefficient. Isolates were categorized to be of the same cluster when their dice similarity index was ≥80%.
