| Outline of Final Research Achievements |
Escherichia coli is one of the most common pathogen in humans. Recent increase in drug-resistant E. coli is an emerging public health threat and is driven by clonal spread of a specific bacterial lineage with drug resistant mechanisms, called ST131. We performed whole genome sequencing analysis of ESBL-producing E. coli collected from multiple Japanese acute care hospitals. CTX-M-27-producing ST131, the most common type in Japan belonged to a novel subclone and was also present outside Japan. The discovery of this novel subclone, named C1-M27, will contribute control of drug resistant E. coli.
