Efficacy of novel vaccines towards Tenacibaculum sp. when administered to Atlantic salmon

Offentlig prosjektsammendrag

Tenacibaculosis is a major welfare problem affecting newly sea transferred Atlantic salmon smolts (Salmo salar) in the salmon farming industry. Historically, the disease caused by the marine bacterium Tenacibaculum sp has resulted in mortalities and large economic losses. Currently, tenacibaculosis outbreaks are managed using antibiotics. However, this is problematic in several ways; it may cause reduced sensitivity against the antibiotic, it is expensive for the farmers and negatively affects the public opinion of the industry. Today, there are no vaccines available that can protect Atlantic salmon against tenacibaculosis, thus there is a need for development of effective vaccines to combat this disease. The primary objective of this study is to assess the capacity for experimental vaccines to protect Atlantic salmon against experimental immersion challenge with Tenacibaculum sp.
