Novel Class 1 Integron (InS21) Carrying bla CTX-M-2 in Salmonella enterica Serovar Infantis

Abstract
The genetic organization of the region coding for CTX-M-2 in Salmonella enterica serovar Infantis was determined by PCR mapping. This gene seems to have been mobilized from the Kluyvera ascorbata chromosome to a complex sulI -type integron, similar to In6 and In7.
