| Outline of Final Research Achievements |
The aim of this study was to design peptide vaccines for infectious diseases of cultured fish, Japanese flounder. Since little is known about the immune system of Japanese flounder at the molecular level, such as haplotypes of major histocompatibility complex (MHC) genes, we inferred the candidates of antigens (i.e. peptide vaccines) by using bioinformatics. In particular, we focused on edwardsiellosis caused by a bacterium, Edwardsiella tarda, surveyed the protein-coding genes, and predicted 11 peptide sequences recognized by MHC of Japanese flounder. After Japanese flounders were inoculated with these peptides, respectively, the infection test by E. tarda was performed. As a result, we found that in three out of 11 peptides the survival rates of Japanese flounder were equal to or larger than that with the positive control treatment.
