| Outline of Final Research Achievements |
DNA analysis of pathogenic microorganisms and tartar from ancient human remains can help in obtaining information such as the origins of diseases and the reproduction of oral environment, which could not be studied by conventional methods. In this study, we pursued the possibility of analyzing ancient pathogens based on the genomic information extracted from human remains. Genomic analysis of pathogenic bacteria failed to produce clear results; however, for the Jomon people, who were considered to be affected by polio, genomic analysis revealed the possibility of them having muscular dystrophy.
In the genomic analysis of oral bacteria of the Jomon and the Edo people, bacterial flora differed between the two, indicating the possibility of a relationship between food intake and oral bacterial flora.
