Study Notes
Protozoan Infections and Immunity
- Protozoal infections often trigger an immune response characterized by both humoral and cell-mediated immunity.
- Humoral immunity, involving antibodies, is essential for neutralizing protozoa and preventing their spread.
- Cell-mediated immunity, relying on T lymphocytes, is crucial for combating intracellular protozoa directly.
- While innate immunity provides the first line of defense against protozoan infections, it is often inadequate to eradicate the parasite.
- The nature of immunity developed after protozoan infections can vary depending on the specific parasite and host species.
- Some protozoa, like Plasmodium falciparum, evade the immune system by altering their surface antigens, making it challenging for the host to develop long-lasting immunity.
- In some cases, reinfection with the same protozoa can occur, highlighting the complexity of immune responses to these parasites.
