Kaplan–Meier survival curve, and infective viral particles in fish sampled during challenge 1. A Accumulated survival of European sea bass in different groups within challenge 1. The different letters indicate the significant differences between experimental groups and between challenges 1 and 2 (Figure 4B) (p < 0.05). B RGNNV titers (TCID₅₀/g) in nervous tissue. C SJNNV titers (TCID₅₀/g) in nervous tissue. Titers in fish from the superinfected group (SJ+RG) were calculated after neutralizing the corresponding genotype.
