Outline of Final Research Achievements

Recently H. cinaedi infection has been increasingly reported.
We analyzed the mechanism of antimicrobial resistance in H. cinaedi, and identified the mutations conferring resistance to ciprofloxacin, clarithromycin, and b-lactams. Moreover the role of efflux pumps to the antimicrobial resistance in H. cinaedi was demonstrated. To elucidate the pathogenetic factors in enterohepatic Helicobacters, the genomes of H. fennelliae MRY12-0050, which is the first report for H. fennelliae, and H. cinaedi strain MRY08-1234 caused nosocomial infection , were analyzed. The suspected pathogenetic factors in H. cinaedi have been investigated to understand H. cinaedi pathogenicity.
