Types of Malaria Parasites
What Are the Different Types of Malaria Parasites?
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)
Falciparum malaria is potentially life-threatening. Patients with severe falciparum malaria may develop liver and kidney failure, convulsions, and coma. Although occasionally severe, infections with P. vivax and P. ovale generally cause less serious illness, but the parasites can remain dormant in the liver for many months, causing a reappearance of symptoms months or even years later.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
