A novel bla(CTX-M-14) gene-harboring complex class 1 integron with an In4-like backbone structure from a clinical isolate of Escherichia coli.

摘要

Escherichia coli BDE0502 contained 3 beta-lactamase genes including bla(DHA-1), bla(SHV-12), and bla(CTX-M-14). The bla(CTX-M-14) gene was found on a complex class 1 integron with an In4-like backbone structure. The bla(CTX-M-14) gene was proceeded by a partial copy of ISEcp1 in addition to the complete copy of ISCR1 element.
