| Outline of Final Research Achievements |
This study aimed at developing effective detection methods for novel human RNA viruses from domestic wastewater using selective metagenomic analysis. Capture probe-based selection followed by next-generation sequencing using illumina MiSeq platform enabled to detect virus genome with relatively low concentration in wastewater. Viral metagenomic analysis revealed that most viral genome sequences are not homologous to any sequences in the database. Based on the metagenome, we constructed contigs that are expected to be from novel viruses. We also confirmed that virus genome with the contig sequence are present in wastewater samples throughout the study period.
