| Outline of Final Research Achievements |
The intestine contains commensal viruses, the majority of which are unidentified bacteriophages (phages). This study revealed many genomes of unknown phages by reconstructing them from metagenomic sequence reads. To understand infectious hosts of the unknown phages, I developed prediction methods of phage-bacteria infectious association based on the phage genomic sequence remaining in the host bacterial genome. After validating the prediction methods, I analyzed the infectious associations of intestinal bacteria / phage in healthy humans and obtained knowledge on symbiotic relationship between phage and bacteria.
