| Outline of Final Research Achievements |
We attempted to determine the causative agent of akoya oyster disease by combination of NGS-based metagenomics and DNA array technology.
Shotgun metagenomic sequences of hemolymph were obtained from diseased and healthy oyster. Common sequences in diseased and healthy oyster were subtracted from the sequences from diseased oyster, and remaining 76,542 sequences were analyzed by Blast homology search. A large portion of the sequence shows homology to eubacteria, but sequences homologous to the animal virus was rare. Candidate sequences of pathogen were narrowed to 1,890 by using DNA microarray that constructed from subtracted 76,542 sequences.
