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

The isolates were recovered from Norwegian produced meat and meat products.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 integronn-t = non-typeableut = unique type, one isolate with this banding pattern was foundAntimicrobial resistant Escherichia coli isolates containing class 1 integrons with the dfrA1-aadA1 cassette array.
