Phylogenetic tree showing the relationship of 76 ESBL-producing E. coli isolates. The dendrogram was constructed by using the nucleotide sequences of the seven housekeeping genes (adk, fumC, gyrB, icd, mdh, purA and recA) of 76 ESBL-producing E. coli isolates from rivers and lakes in Northwest China with the maximum likelihood method. Sampling sites, phylogenetic group (PG), sequence type (ST) and ST clonal complex (STcc) were displayed the right of the dendrogram
