aClass 1 integrons for which only partial sequences of gene cassette arrays were amplified (IS26 detected in NO.47685 strain, dfrA14 detected in NO.45016 strain). bClass 1 integrons for which PCR failed to amplify the gene cassette array. cA total of 110 integrants were detected from 96 integron positive strains. ∗The gene cassette combination that our research group has previously reported.
