Research Abstract |
By performing a series of genome sequencing and functional analyses of enterohemorrhagic Ecsherichia coli (EHEC) and related enteropathogens. we succeeded in developing a rapid O157 EHEC strain typing system, obtaining the complete genome sequences of three major non-O157 EHECs, and improving our understanding of functions and evolution mechanisms of type III secretion mechanisms and other virulence systems of these pathogens. In addition, we succeeded in clarifying the genetic and functional differences of adult and infant gut microbiota by comparative metagenomic analysis and obtaining the complete genome sequences of 3 bacterial species (4 strains, including an unculturable bacterium) residing in intestine.
