Of 1,456 strains isolated from 2001 to 2003 demonstrating resistance to either oxyimino-cephalosporin, 317 strains, isolated in 57 of 132 clinical facilities, were found to harborbla CTX-M genes by PCR. Fifty-seven, 161, and 99 strains harboredbla CTX-M genes belonging to thebla CTX-M-1 ,bla CTX-M-2 , andbla CTX-M-9 clusters, respectively.
