Study Notes

Tropische ziekten - Malaria

Malaria: a disease caused by parasites that are transmitted through the bite of infected female Anopheles mosquitoes.
Symptoms: The text mentions symptoms may include fever, chills, and headache, but doesn't provide specific details.
Transmission: Mosquito bites transmit the malaria parasite, Plasmodium.
Mosquito life cycle: The Anopheles mosquito, specifically the female, is the vector for malaria.
Human role: Humans are an intermediate host for the malaria parasite.
Stages of parasite development in the mosquito:
- Merozoites enter the mosquito's bloodstream
- Merozoites reproduce in the mosquito's intestine.
- The parasites undergo a life cycle process in the mosquito's body, forming sporozoites.
- Sporozoites migrate to the mosquito's salivary glands, ready to be transmitted.
Stages of parasite development in the human:
- Sporozoites are injected by the mosquito bite into the human host.
- They infect liver cells (hepatic cells).
- They form merozoites within that infected tissue.
- Merozoites infect red blood cells.
- Once inside red blood cells, the merozoites multiply and cause the characteristic symptoms.

History/Misconception of Malaria

Early beliefs: People thought malaria was caused by "bad air" coming from swamps and marshes.
Modern understanding: The disease is caused by parasites transmitted by mosquitos.
