Effectiveness of a vaccine against red sea bream iridoviral disease in various cultured marine fish under laboratory conditions

摘要

The effectiveness of a vaccine made of the cell culture supernatant of RSIV (red sea bream iridovirus)infected cells inactivated with formalin (0.1% v/v) in yellow-tail Seriola quinqueradiata, amberjack S. dumerili, kelp grouper Epinephlelus moara, striped jack Pseudocaranx dentex and spotted parrot fish Oplegnathus punctatus was evaluated under experimental conditions. Juvenile or young fish were intraperitoneally injected with the vaccine, and challenged with RSIV by intraperitoneal injection at 10th day post-vaccination. Statistical analysis showed significantly higher survival rates in the vaccinated groups of all tested fish species.
