Abstract
The variable presence of integrons among extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae species (0 to 66%) is described. Association between bla ESBL and integrons occurred when these are linked to specific ESBL-type genes (In 60 bearing IS CR1 and bla CTX-M-9 ) or when ESBL genes were superimposed onto selected plasmids carrying integrons. Some integrons were identical to those found during decades worldwide, illustrating the preservation of the genetic elements carrying them.Keywords
