Hypothesis
How does the absence of the symbiotic bacterium Wigglesworthia affect the immune responses of tsetse flies?
Conclusion
Wigglesworthia is essential for the proper development and functioning of the immune system in tsetse flies.
Supporting Evidence
- Tsetse flies without Wigglesworthia are more susceptible to infections.
- Phagocytosis is crucial for the immune response in tsetse flies.
- Adult flies lacking Wigglesworthia have fewer immune cells.
Takeaway
Tsetse flies need a specific bacteria to help them fight off infections. Without it, they get sick easily.
Methodology
The researchers produced larvae without Wigglesworthia by feeding pregnant female flies antibiotics and then tested their immune response by injecting them with E. coli.
