The genetic organization of the gene coding for DHA-1 and the correspondingampR gene was determined by PCR mapping. These genes have been mobilized from theMorganella morganii chromosome and inserted into a complexsulI -type integron, similar to In6 and In7. However, they are not themselves mobile cassettes. This integron probably includes a specific site for recombination allowing the mobilization of diverse resistance genes, as observed forbla CMY-1 andbla MOX-1 .
