PCR classification of CTX-M-type beta-lactamase genes identified in clinically isolated gram-negative bacilli in Japan

Antimicrob Agents Chemother. 2006 Feb;50(2):791-5. doi: 10.1128/AAC.50.2.791-795.2006.

Abstract

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 harbor bla(CTX-M) genes by PCR. Fifty-seven, 161, and 99 strains harbored bla(CTX-M) genes belonging to the bla(CTX-M-1), bla(CTX-M-2), and bla(CTX-M-9) clusters, respectively.
