Figure 6From: Piscine orthoreovirus infection in Atlantic salmon (Salmo salar) protects against subsequent challenge with infectious hematopoietic necrosis virus (IHNV)Haematocrit and haemoglobin levels are reduced by PRV and IHNV infection. Haematocrit levels (A) and haemoglobin levels (B) monitored in experimental groups (PRV−/IHNV−, PRV+/IHNV−, PRV−/IHNV+, PRV+/IHNV+) during pathogenesis trial. Mean level and SD from the different groups at selected time points are indicated by vertical lines.Back to article page
