Communications: Protective Immunity Induced by a Commercial Vibrio Vaccine in Hybrid Striped Bass |
| |
Abstract: | Abstract Commercial Vibrio anguiliarum-V. ordalii bacterin was used to vaccinate hybrid striped bass (Morone saxatilis ♀ × M. chrysops ♂) to test the vaccine efficacy against vibriosis. Vaccination by direct immersion of fish in diluted Vibrio vaccine for 20 s resulted in increased protective immunity. The relative percent survival of hybrid striped bass challenged 35 d after vaccination was 66.7% for those challenged by 1-h immersion exposure to 7.03 × 107 V. anguillarum cells/mL, 75.0% for those challenged by injection with 3.51 × 105 cells/fish, and 86.7% for those challenged by injection with 3.51 × 104 cells/fish. |
