Abstrakt: ABSTRACTExtended-spectrum AmpC β-lactamase (ESAC) Escherichia coliproducers were investigated over a 5-year period. Eleven isolates presenting a strong ampCpromoter and different strategic AmpC mutations, including two newly described modifications (A292V and an L-A-A insertion at 295), were characterized. All the isolates belonged to phylogenetic group A and to the ST23 complex.
