A Formalin‐Inactivated Vaccine Enhances Survival and Mitigates Horizontal Transmission of Red Sea Bream Iridovirus (RSIV) in Rock Bream (Oplegnathus fasciatus): Insights From Viability Quantitative PCR

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Formalin‐inactivated vaccines are widely employed as a primary preventive strategy against red sea bream iridoviral disease (RSIVD), which poses a substantial economic threat to the aquaculture of rock bream (Oplegnathus fasciatus). However, conventional quantitative PCR (qPCR) cannot differentiate infectious virions from noninfectious vaccine
