Outline of Final Research Achievements |
In this study, we aimed at collection of information about a bacteriophage-exclusion system (restriction-modification system) in Helicobacter pylori, to develop an effective sterilization method of drug-resistant H. pylori from the stomach using bacteriophages KHP30 and KHP40. The results indicated that H. pylori had multiple functional restriction-modification systems, suggesting strongly that the bacteriophages must be adapted to all H. pylori-possessed restriction-modification systems for effective sterilization.
