Highlights

•    No potential ESBL/AmpC producing E. coli isolates from Quebec poultry farms were colistin-resistant or possessed mcr (12) genes
•    Two potential ESBL/AmpC producing E. coli isolates from Senegal poultry farms were colistin-resistant but mcr (12) gene negative
•    Mutations in the PmrAB system of colistin-resistant E. coli from Senegal were detected, including one mutation not previously described in isolates of animal origin
•    Eleven potential ESBL/AmpC producers E. coli isolates from Vietnam poultry farms were colistin-resistant and mcr-1 gene positive
•    All colistin resistant, ESBL/AmpC genes E. coli were highly multidrug resistant
