Antimicrobial resistant Escherichia coli isolates containing class 1 integrons with an aadA1 cassette as the only inserted gene cassette.

The isolates were recovered from humans with blood stream infections.aTransferability of plasmids with class 1 integron by conjugation; + = transconjugants were obtained, ÷ = no transconjugantes were obtainedbPBRT = Plasmid-based replicontyping (plasmid replicon(s) in transconjugant)cSubtyping of conjugative incF plasmid with class 1 integronut = unique type, one isolate with this banding pattern was foundAntimicrobial resistant Escherichia coli isolates containing class 1 integrons with an aadA1 cassette as the only inserted gene cassette.
