Characterization of plasmids encoding blaESBL and surrounding genes in Spanish clinical isolates of Escherichia coli and Klebsiella pneumoniae

Abstract

A diversity of the plasmid incompatibility groups that harbour blaESBL genes was observed, except for the blaCTX-M-14 gene. Moreover, a high variability was confirmed in the genetic environment of these genes as a result of insertion and deletion events.
