Abstract
The three clonal groups investigated accounted for 30% of the multidrug-resistant isolates, which gives evidence of an important clonal component in the emergence of resistances among extraintestinal pathogenic E. coli. Notably, a single high virulence clonal group (O25b:H4-B2-ST131) causes approxim …
