Question

Describe the life cycle of Plasmodium Vivax in mosquito.

Answer 1

During a blood meal, a malaria-infected female Anopheles mosquito inoculates sporozoites into the human host . ... Merozoites infect red blood cells . The ring stage trophozoites mature into schizonts, which rupture releasing merozoites . Some parasites differentiate into sexual erythrocytic stages (gametocytes)

Answer 2

Ans- In the mosquito gut, the microgamete nucleus divides three times producing eight nuclei; each nucleus fertilizes a macrogamete forming a zygote. The zygote, after the fusion of nuclei and the fertilization, becomes the so- called ookinete. The ookinete, then, penetrates the midgut wall of the mosquito, where it encysts into a formation called oocyst. Inside the oocyst, the ookinete nucleus divides to produce thousands of sporozoites that travel to salivary glands and are transferred to humans.
