Outline of Final Research Achievements

Helicobacter hepaticus (H. hepaticus) is a gram-negative, spiral shaped microaerophilic bacterium. Several studies have suggested the possibility that infection of this bacterium plays a role in the pathogenesis of liver diseases in humans. We evaluated the association between H. hepaticus and children with liver disorders. Furthermore, we detect the antigenic H. hepaticus protein recognized by child sera using 2-DE immunoblot analysis. Positive rate of H. hepaticus in children without and with liver disorders was 30.3% (10/33) and 44.4% (4/9), respectively. Total 25 proteins were identified as candidate antigens by LS-MS/MS after the 2-DE immunoblot analysis. Among the proteins, flagelin A was the most reactive protein, particularly against highly reactive sera, although low reactive sera also detected the spot slightly.
