| Outline of Final Research Achievements |
To investigate the epidemiological status of influenza D virus infection in cattle in Japan, we detected a strain of influenza D virus in Japan that was phylogenetically different from the previously reported strains of influenza D virus. Furthermore, we isolated this new virus and we found that the new strain was antigenicity different from previously known strains.
We also successfully developed a reverse genetics system of influenza D virus, which is an important tool for analyzing viral properties. Furthermore, using this reverse genetics system, we succeeded in producing an 8-segmented virus.
