Hypothesis
Does maternal immunization in zebrafish enhance the immune response of their offspring against pathogens?
Conclusion
Maternal immunization with Aeromonas hydrophila significantly increases the immune factors in both mothers and their offspring, providing enhanced protection against bacterial challenges.
Supporting Evidence
- Immunization of female zebrafish led to increased levels of complement components C3 and Bf in both mothers and their eggs.
- Embryos from immunized mothers showed significantly lower mortality rates when challenged with A. hydrophila compared to those from unimmunized mothers.
- Blocking C3 and Bf activities in embryos resulted in increased susceptibility to A. hydrophila.
Takeaway
When mother zebrafish get vaccinated, they pass on extra protection to their babies, helping them fight off germs better.
Methodology
The study involved immunizing female zebrafish with formalin-killed Aeromonas hydrophila and measuring the levels of complement components and hemolytic activity in both mothers and their offspring.
Limitations
The study primarily focuses on a single pathogen and may not generalize to other pathogens or environmental conditions.
Participant Demographics
Sexually-mature female zebrafish, aged 6 months.
