Characterization of Integrons and Antimicrobial Resistance in Escherichia coli Sequence Type 131 Isolates

Figure 1

Dendrogram generated by bionumerics software that demonstrates the relationship of 22 integron-positive E. coli ST131 isolates at 70% similarity level, after digestion with XbaI. Strain designation, sample source, and O serotype are shown. The analysis of the bands generated was performed using the Dice coefficient and unweighted pair group method.
