What is life cycle of Plasmodium vivax?
Plasmodium is a unicellular eukaryotic organism. It is a sporozoan and has a spore-like infectious stage in its life cycle. It completes its life cycle in two hosts, i.e. humans and female Anopheles mosquitoes….Classification and Characteristics.

What does Plasmodium vivax look like?
P. vivax gametocytes are round to oval with scattered brown pigment and may almost fill the rbc. Schüff- ner’s dots may appear more fine in comparison to those seen in P. ovale.
What are the stages in the life cycle of Plasmodium?
Plasmodium parasites have a complex life cycle that includes three stages namely Gametocytes, Sporozoites and Merozoites. The male gametocytes called microgametocytes and female gametocytes called macrogametocytes are transmitted through an anopheles mosquito during a blood meal.
Where does Plasmodium vivax live?
Plasmodium vivax is found mainly in Asia, Latin America, and in some parts of Africa. P. vivax is believed to have originated in Asia, but recent studies have shown that wild chimpanzees and gorillas throughout central Africa are endemically infected with parasites that are closely related to human P. vivax.
How do you identify Plasmodium vivax under a microscope?
Identifying Plasmodium vivax under a microscope Malaria parasites can be identified by examining a drop of the patient’s blood under a microscope, spread out as a “blood smear” on a microscope slide. To give the parasites a distinctive appearance, the specimen is stained prior to examination.
How does Plasmodium multiply also draw diagram?
Explanation: In humans, the parasites grow and multiply first in the liver cells and then in the red cells of the blood. In the blood, successive broods of parasites grow inside the red cells and destroy them, releasing daughter parasites (“merozoites”) that continue the cycle by invading other red cells.
What is the malaria incubation period for P vivax?
Usually, these periods vary depending on the species of Plasmodium causing malaria. The average incubation period is 9-14 days for Plasmodium falciparum, 12-17 days for infections by Plasmodium vivax and 18-40 days for infections caused by Plasmodium malariae [1].
What is the shape of malaria parasite?
The Parasite Depending on the developmental stage and species, malaria parasites can be spherical, ring shaped, elongated, or crescent shaped, and can range in size from 1 to 20 microns in diameter (1 micron equals 1 millionth of a meter or approximately 125,000 of an inch).
What is the meaning of Plasmodium vivax?
[ vī′văks′ ] n. A protozoan that is the most common malarial parasite of humans, causing vivax malaria.
Where is P. vivax found?
Plasmodium vivax is found mainly in Asia, Latin America, and in some parts of Africa. P. vivax is believed to have originated in Asia, but recent studies have shown that wild chimpanzees and gorillas throughout central Africa are endemically infected with parasites that are closely related to human P.
How does Plasmodium vivax cause malaria?
Malaria parasites are transmitted from the mosquito to its human host in the form of sporozoites during a blood meal. These immediately migrate to the liver where they invade hepatocytes and form schizonts. When these schizonts rupture, Plasmodium merozoites are released into the blood.
