Efficacy of Aeromonas hydrophila S-layer bacterins with different protein profiles as a vaccine in Nile tilapia (Oreochromis niloticus)

Farming of Nile tilapia is in full development throughout the world. However, an increase is still seen in the prevalence and severity of bacterial diseases. The aim of this study was to develop a vaccine against Aeromonas hydrophila in Nile tilapia (Oreochromis niloticus) based on protein patterns of S-layer proteins. The proteins were extracted using glycine and NaOH with subsequent visualization through SDS-PAGE. Based on the protein patterns...
