Influence of vaccination on vibriosis resistance of the giant black tiger shrimp Penaeus monodon (Fabricius)

The study aims to test the influence of vaccination with polyvalent vaccine prototypes on the vibriosis resistance of Penaeus monodon. Vaccinated P. monodon post-larvae were challenged with a virulent Vibrio alginolyticus strain 10, 20, and 30 days post-vaccination. Results showed that vaccination significantly enhances the resistance of shrimp to vibriosis. This effect decreased by age of the post-larvae, particularly for the glucan group.
