What is the life cycle of the Plasmodium parasite?
In addition, the parasite has developed a series of strategies that allow it to confuse, hide, and misdirect the human immune system. Malaria infection begins when an infected female Anopheles mosquito bites a person, injecting Plasmodium parasites, in the form of sporozoites, into the bloodstream.
What are the three stages in the life cycle of Plasmodium?
Life Cycle Of Malaria Parasite. This malaria parasite called plasmodium completes its life cycle in three stages namely Gametocytes which is the first stage then sporozoites which is the second stage and lastly merozoites which is the third and final stage.
What is the infective stage of parasite?
The infective stage of a parasite is one in which the parasite is capable of entering its host and continue its development within the host. Infection in connection with parasitology is defined as an invasion of the body by an endoparasite thereby inciting reaction from the host’s immune system.
What are the four types of Plasmodium?
The Disease Four kinds of malaria parasites infect humans: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae.
What is the normal life cycle of Plasmodium?
Such a two host life cycle is digenetic. Intermediate host is female Anopheles. In human body the parasite multiplies asexually while in female anopheles it undergoes a sexual cycle followed by an asexual multiplication called sporogony. The normal adult or trophozoite phase of plasmodium occurs in RBCs of human beings.
What are the different types of Plasmodium parasites?
Some other species of plasmodium known to spread Malaria are P. vivax, P. ovale, P. malariae, and P. knowlesi. The plasmodium parasite displays a complex life cycle as it uses an insect (mosquito) as a catalyst to carry and transmit the disease.
What kind of host does Plasmodium falciparum have?
In the life cycle of plasmodium falciparum, a mosquito acts as the definitive host. As such, it supports the adult form of the parasite that is capable of sexual reproduction.
Where does the asexual phase of Plasmodium begin?
Life Cycle of Plasmodium Species. The life cycle of Plasmodium species generally exist within the two phases (asexual and sexual) or require two living hosts (vertebrates and mosquito). Plasmodium’s asexual phase begins within the female Anopheles mosquito’s stomach, while the sexual phase starts within the human beings’ hepatic cells.
