Antimicrobial resistant <i>Escherichia coli</i> isolates containing class 1 integrons with the <i>dfrA1-aadA1</i>cassette array.

The isolates were recovered from humans with blood stream infections. aTransferability of plasmids with class 1 integron by conjugation bPBRT = Plasmid-based replicontyping (plasmid replicon(s) in transconjugant); + = transconjugants were obtained, ÷ = no transconjugantes were obtained cSubtyping of conjugative incF plasmid with class 1 integron ut = unique type, one isolate with this banding pattern was found Antimicrobial resistant Escherichia coli isolates containing class 1 integrons with the dfrA1-aadA1cassette array.
