Abstract
Integrons were detected in 37 (72.5%) of 51 Klebsiella spp. producing extended-spectrum beta-lactamases by PCR with primers that targeted integrase genes and cassette regions. PCR and amplicon sequencing of the cassette regions revealed aadB and aadA2 gene cassettes that confer resistance to a range of aminoglycosides. aadB was associated with a class 1 integron on a 28-kb plasmid, pES1, that also contained bla SHV-12 and IS 26 .Keywords
