Female mosquito’s - Anopheles.
What cycle takes place in the gut of the mosquito?
Sporogonic multiplication.
What does synchronous mean?
Occuring at the same time.
How is malaria diagnosed?
- Using microscope.
- Molecular diagnosis.
- Antibody detection.
- Immunological detection.
Outline the life (sporogonic) cycle of the plasmodium parasite in vector?
- Gametocytes ingested by mosquito.
- Develope into oocysts in mosquito gut.
- Oocysts release sporozoites into mosquito saliva.
- Sporozoites mature into schizonts.
Outline the life (erythrocytic) cycle of plasmodium in host?
- Merozoites infect red blood cells.
- Merozoites become (the ringed staged) trophozoites.
- Trophozoites mature into schizonts.
