Abstract: Two Klebsiella pneumoniae clinical strains (K96005 and K13) producing CTX-M-2 were isolated from hospitalized patients in Uruguay during 1996 and 2003 and studied. The genomic surroundings of blaCTX-M-2 were characterized by PCR mapping and DNA sequencing. The results showed that blaCTX-M-2 was included in a complex class-1 integron (InK13), associated with an orf513 in both isolates. The genetic array of the integron, aac(6′)-lb, blaOXA-2, orfD (gene cassette region), associated with an orf513-blaCTX-M-2, seemed to be widely disseminated over the Río de la Plata region.
