Survival rates of carp infected with the CyHV-3 LUC strain. On day zero, three groups of fish, each consisting of 17 common carp (mean weight of 10 g) kept in separate tanks, were infected either by bathing them in water containing the virus (left graph, immersion) or by feeding them with food pellets contaminated with the virus (middle and right graphs, Oral) as described in Materials and Methods. The fish were examined daily for clinical signs of CyHV-3 disease, and dead fish were removed. The percentage of survival is expressed according to time post-infection.
