Describe the life cycle of Plasmodium from the time it enters the human body till a female Anopheles mosquito bites an infected person.
Show Hint
Understanding the Plasmodium life cycle is crucial for malaria prevention and treatment strategies.
Solution and Explanation
The life cycle of Plasmodium: Sporozoites enter the human bloodstream via a mosquito bite and infect liver cells. They multiply in liver cells to form merozoites, which are released into the bloodstream. Merozoites infect red blood cells, multiply, and cause cell rupture. Gametocytes are formed and circulate in the blood. When a mosquito bites, gametocytes are taken up, continuing the cycle.
