Outline of Final Research Achievements

To examine the interactions between the evolution of an emerging Cyprinid herpesvirus 3 (CyHV3) and the population genetic structures of host common carp (Cyprinus carpio), I developed an environmental DNA-based method to evaluate the carp population genetic structures and performed a preliminary survey of CyHV3 genetic variations. The environmental DNA method successfully provided quantitative estimates for the proportion of genotypes in wild carp populations. CyHV3 collected from natural water bodies several years after its introduction had multiple genotypes, even though a single genotype was initially spread in Japan, suggesting that CyHV3 evolved after its introduction.
