| Outline of Final Research Achievements |
This research project was conducted to reveal molecular mechanisms by which avian rotavirus A (RAV) induces pathogenicity in mammals. Firstly, we analyzed genome sequences from 3 avian RAVs and compared them with sequences of avian RAVs from various species. We discovered unique genome sequences in the 2 RAVs, which were certificated as novel genotypes by the Rotavirus Classification Working Group. Next, we tried to establish a reverse genetics system for the avian RAV PO-13 strain to explore its pathogenicity to mammals. We constructed the reverse genetics system using T7 and polII promoter for synthesis of virus RNAs. Neither of the systems resulted in virus rescue. We, however, detected RAV specific replicon activity in the polII promoter system, indicating that the replication and transcription by the RAV polymerase could be induced artificially.
