Table 1 Overview of dose–response from bath challenge of SAV3 in Atlantic salmon post-smolt

From: Relationship between viral dose and outcome of infection in Atlantic salmon, Salmo salar L., post-smolts bath-challenged with salmonid alphavirus subtype 3

Treatment SAV3 exposure dose (TCID50 L−1 of seawater) Prevalence of viraemic fish (%) Prevalence of SAV3-positive heart (%) Viral shedding rate in tank-seawater (TCID50 h−1 kg−1)
Low 7 4 0 1364
Medium 27 21 25 7113
High 139 81 63 24 129
  1. Prevalence of viraemic fish, prevalence of SAV3-positive heart and viral shedding rate in the tank-seawater at 10 dpe are shown for each infection dose.
