Diverse Escherichia coli lineages from domestic animals carrying colistin resistance gene mcr-1 in an Ecuadorian household
Objective: The aim of this study was to detect potential animal reservoirs of Escherichia coli carrying the mcr-1 gene in an Ecuadorian household.Methods: The mobile colistin-resistance gene, mcr-1, was first detected in Ecuador in a commensal E.coli isolate from a boy.A cross-sectional study was performed to detect the possible source of colistin-
