Hypothesis
Can transgenic Schizochytrium limacinum serve as an effective oral vaccine carrier in aquaculture?
Conclusion
The study found that Schizochytrium limacinum SR21 can effectively act as an oral vaccine carrier, enhancing immune responses in zebrafish and koi carp.
Supporting Evidence
- Zebrafish fed with recombinant Schizochytrium showed specific immune responses in the intestine.
- Expression levels of immune-related genes were significantly upregulated post-immunization.
- Koi carp fed with recombinant Schizochytrium exhibited increased production of specific antibodies.
Takeaway
This study shows that a special type of algae can help fish get better protection against diseases when they eat it.
Methodology
The study involved feeding zebrafish and koi carp with recombinant Schizochytrium expressing the FBA antigen and assessing immune responses.
Limitations
The study did not evaluate long-term immune effects or the safety of using transgenic microalgae in natural environments.
Participant Demographics
Zebrafish (Danio rerio) and koi carp (Cyprinus carpio koi) were used as model organisms.
