Which parasite is malaria parasite?
Malaria parasites are micro-organisms that belong to the genus Plasmodium. There are more than 100 species of Plasmodium, which can infect many animal species such as reptiles, birds, and various mammals. Four species of Plasmodium have long been recognized to infect humans in nature.
What are the 5 parasites that cause malaria?
Five species of Plasmodium (single-celled parasites) can infect humans and cause illness:
- Plasmodium falciparum (or P. falciparum)
- Plasmodium malariae (or P. malariae)
- Plasmodium vivax (or P. vivax)
- Plasmodium ovale (or P. ovale)
- Plasmodium knowlesi (or P. knowlesi)
How do parasites affect the spread of malaria?
The malaria parasites enter that person’s bloodstream and travel to the liver. When the parasites mature, they leave the liver and infect red blood cells. Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.
What is the incubation period of malaria parasite?
Following the infective bite by the Anopheles mosquito, a period of time (the “incubation period”) goes by before the first symptoms appear. The incubation period in most cases varies from 7 to 30 days. The shorter periods are observed most frequently with P. falciparum and the longer ones with P.
Which stage of malaria parasite is responsible for relapse?
On the fusion of macrogamete and microgamete, the zygote develops which attaches to the gut lining of mosquitoes. On maturation of the oocyte, Sporozoite is released in salivary glands of mosquitoes. Therefore, Hypnozoite is responsible for relapse of malarial symptoms.
Which of the following malaria parasite has the longest incubation period?
The incubation period in most cases varies from 7 to 30 days. The shorter periods are observed most frequently with P. falciparum and the longer ones with P. malariae.
