Question

Describe the life cycle of Plasmodium from the time it enters the human body till a female Anopheles mosquito bites an infected person.

Hint:

Understanding the Plasmodium life cycle is crucial for malaria prevention and treatment strategies.

Answer 1

Plasmodium Life Cycle: Following a mosquito bite, sporozoites are introduced into the human bloodstream, subsequently infecting liver cells. Within liver cells, they proliferate, generating merozoites that are then released into the bloodstream. Merozoites proceed to infect red blood cells, where they multiply and induce cell lysis. Gametocytes develop and are circulated in the blood. When a mosquito feeds, it ingests these gametocytes, thereby perpetuating the cycle.
