Abstract excerpt

We investigated the molecular characteristics of ESBL-producing Escherichia coli in Japan. A total of 101 clinical isolates of ESBL-positive E. coli collected in Japan between June 2008 and November 2009 were studied. Among the 101 strains, 97 were positive for CTX-M, while 47 and two were positive for TEM and SHV, respectively. Sequencing revealed that CTX-M-14 was most common (49/101), followed by CTX-M-27...
