Association of the blaCMY-10 gene with a novel complex class 1 integron carrying an ISCR1 element in clinical isolates from Korea

The blaCMY-10 gene responsible for β-lactam resistance was located on a new complex class 1 integron within a conjugative plasmid. The sul1-type class 1 integron, containing an aadA2a gene cassette, was identified upstream of blaCMY-10. A unique gene array (yqgF–yqgE–gshB–orf97—orf105) was identified downstream of blaCMY-10.
