Get some meaty sausages

Question 8

Parasite life cycle detailed

Answer 8

1. Mosquito bites infected patient and takes up Gametocytes
   These reproduce sexually inside mosquito
   In salivary glands they change to sporozoites
2. Mosquito bites another animal, sporozoites transferred into blood stream and travel to liver
   Enter liver cells and reproduce asexually to produce merozoites
3. Released into blood from liver cells where they invade red blood cells
   Then.. Either
   A) enter sexual phase of reproduction resulting in Gametocytes to begin cycle again once rebitten
   Or…
   B) grow and nucleus then divides asexually to produce a cell with many nuclei called a schizont
4. The schizont divides to produce many merozoites
   Red blood cells burst releasing mereozoites- toxins released to in waves fever attacks
   Cycle repeated
