| Outline of Final Research Achievements |
Understanding the transboundary movement of microorganisms is a significant public health issue. It is possible that large amounts of various bacteria existing on the earth’s surface are spreading across borders through migratory birds, but their identities and rates of migration have yet to be elucidated. In this study we employed next-generation sequencing technology targeting the 16S rRNA gene for comprehensive clarification of the sampled bacterial communities associated movement with migratory birds. We collected the fecal samples of swallow, Eurasian wigeon, and seagull in western Japan and the coastal areas of eastern Hokkaido. Our studies revealed the differences in gut microbiota among the avian and other host species. The genetic characteristics of multidrug resistant bacteria contained in fecal samples were also clarified.
