Plasmodium Ovale

Plasmodium ovale is a species of Plasmodium malaria parasite that has a 48-hour reproduction cycle (schizogony) and is the causative agent of tertian malaria. This type of malaria has a relatively benign course and is distributed mainly in tropical Africa, and is also found on the island of New Guinea and the Philippines.

Main characteristics of Plasmodium ovale:

  1. The development cycle lasts 48 hours, so febrile attacks are repeated every three days (hence the name “three-day malaria”)

  2. The parasite infects red blood cells, like other types of malarial plasmodia

  3. The incubation period ranges from 12 to 20 days

  4. The disease is relatively mild, relapses are rare

  5. Widely distributed in West and Central Africa, also found in parts of Southeast Asia

  6. The vector is mosquitoes of the genus Anopheles

  7. Diagnosis is based on detection of the parasite in blood smears

  8. Treatment is with antimalarial drugs such as chloroquine

Thus, Plasmodium ovale causes a relatively benign form of malaria confined to the tropical regions of Africa and Southeast Asia. The development cycle of the parasite lasts 48 hours, which is manifested by characteristic attacks of fever every three days. Treatment involves the use of antimalarial drugs.



Plasmodium ova is a species of plasmodium characterized by a 48-hour duration of schizogony. It is found in tropical and subtropical Africa, on the island of New Guinea, the Philippines and other regions. It is the causative agent of tertian malaria.

The disease caused by this parasite has a relatively benign course. In this type of malaria, a person experiences bouts of fever after 3 days, but without complications such as anemia, liver and kidney dysfunction, making it less dangerous than other types of malaria, which can lead to death.

However, despite its relatively low mortality rate, Plasmodium ovale remains a major public health problem in regions where it is prevalent. Control of this parasite includes the use of antimalarial drugs and the prevention of malaria through the use of repellents, water purification and hygiene. In addition, it is important to regularly diagnose and treat malaria to prevent its spread and maintain public health.
