| Outline of Final Research Achievements |
This study conducted observation of changes in the appearance of intrabranchial black body (IBB), the virus propagation in various organs and the mortality in the experimentally infected fish, histopathological examinations of IBBs, and characterization of IBBs isolated from the branchial cells. Light and electron microscopies revealed the presence of heterogenous IBBs comprising fine granules in the lamella capillaries and reducing substances in IBB including melanin. The appearance of IBB is suggested to be closely related to melanin synthesis induced by activation of defense mechanisms against infectious viruses.
