Notes:
The relative degree and duration of protection against Vibrio anguillarum and Pasteurella piscicida in sea bass vaccinated once by immersion at 1 g was compared with fish vaccinated by immersion at 1 g and revaccinated at 5 g by immersion or intraperitoneal (i.p.) injection. The vaccines used were based on V. anguillurum (serotype O1) and P. piscicida. The groups of fish were challenged with both pathogens separately at 7 weeks and 26 weeks post revaccination. Sea bass vaccinated by immersion at 1 g and again at 5g by immersion or injection, demonstrated a significant level of protection against V. anguillarum lasting for 26 weeks post revaccination. Sea bass revaccinated by immersion were significantly protected against P. piscicida 7 weeks post revaccination compared with nonvaccinated fish. Failure in killing nonvaccinated sea bass during the latter pasteurellosis challenge renders duration of protection against P. piscicida beyond 7 weeks post revaccination as inconclusive. No long-term protection was measured against either pathogen in the fish vaccinated at 1 g.
