Novel use of Quillaja saponaria extracts to prevent viral infections in Atlantic salmon: in vitro ISAv and IPNv inhibition and in vivo protection against IPNv

Key Points

• Quillaja saponaria extracts demonstrate significant inhibition of viral infections in both in vitro and in vivo settings.
• In vitro assays reveal that extracts effectively inhibit ISAv and IPNv, which are harmful to salmon populations.
• Observational analysis of Atlantic salmon shows promising results in reducing infections using natural extracts.
• Adopting these extracts may enhance environmentally friendly practices in aquaculture, supporting industry sustainability.
