Novel complex sul1-type integron in Escherichia coli carrying bla(CTX-M-9)

Antimicrob Agents Chemother. 2002 Aug;46(8):2656-61. doi: 10.1128/AAC.46.8.2656-2661.2002.

Abstract

For the present report, a novel complex class 1 integron, In60, was characterized. Part of this integron includes the bla(CTX-M-9) gene and its downstream nucleotide sequence, which shares 81% and 78% nucleotide identity with those of kluA-1 beta-lactamase and orf3 of K. ascorbata, respectively. Furthermore, a new insertion sequence, IS3000, has been found in In60. PCR analysis indicates that integron In60 is present in 33 of 34 nonclonal enterobacterial isolates carrying the putative beta-lactamase CTX-M-9.
