Conclusion
Vector-borne pathogens use antigenic variation to evade the immune system and prolong their survival in hosts.
Supporting Evidence
- Pathogens like Borrelia and African trypanosomes use antigenic variation to evade the immune response.
- Antigenic variation can complicate vaccine development against these pathogens.
- Different pathogens have evolved similar genetic mechanisms for antigenic variation.
Takeaway
Some germs can change their appearance to trick our body's defenses, making it hard for us to fight them off.
Limitations
The review is limited to pathogens that rely on vectors for transmission and may not cover all forms of antigenic variation.
