Title: The attenuation mechanism of live attenuated vaccine P7-P8 against cyprinid herpesvirus 2 infection potentially involving apoptosis of the infected cell in fish
Although we have succeeded in developing a safe and highly effective live attenuated vaccine against herpesvirus hematopoietic necrosis, the principle behind its attenuation is still unknown. In this presentation, we investigated the immune response induced by the vaccine, as well as a series of mutations in the genome sequence of the virus during the attenuation process. The immune response in which cytotoxic T cells attack infected cells and induce apoptosis can be avoided by the action of a viral protein that inhibits apoptosis in highly virulent viruses, but vaccines have a deletion mutation in this gene. It was inferred that the infected cells were eliminated by apoptosis and were not toxic to fish.

Title: Infectious hematopoietic necrosis (IHNV) persistence in rainbow trout surviving in experimental infection
Infectious hematopoietic necrosis(IHN)It is thought that the virus infects rainbow trout, and that the infection continues after the deaths have stopped, but the virus cannot actually be isolated from the fish. In this presentation, it was found that the virus could not be isolated after the fish had died, but if immunosuppressants were administered to the fish several times, the virus could be isolated, and the virus persisted for at least one month. proved to be contagious.
