Plasmodium vivax

1. Unraveling the Mystery of Plasmodium vivax This presentation will delve into the intricate life cycle, pathogenicity, transmission, diagnosis, treatment, and control measures of Plasmodium vivax, a prevalent human malaria parasite. by Maheshwar Jamadar

2. Life Cycle and Schematic Representation 1 The parasite begins its life cycle as a sporozoite, transmitted through mosquito bites and infecting human liver cells. 2 These merozoites invade red blood cells, multiplying and causing symptoms of malaria as they burst and release new parasites. 3 The parasite develops into gametocytes in the blood, which are taken up by mosquitoes during a blood meal, completing the cycle.

3. Pathogenicity Symptoms of Infection Fever and Chills Recurring episodes of high fever, accompanied by chills, sweating, and headache. Fatigue and Weakness General fatigue, muscle aches, and weakness are common symptoms. Other Symptoms Other symptoms may include nausea, vomiting, abdominal pain, and joint pain.

4. Transmission and Vector Biology Anopheles Mosquito The Anopheles mosquito is the primary vector for Plasmodium vivax transmission. It transmits the parasite during its blood meal. Vector Biology The mosquito species, its breeding habitats, and its feeding behavior influence the spread of malaria.

5. Diagnosis and Detection of Infection Microscopy Microscopic examination of blood samples is a common method for detecting Plasmodium vivax parasites. Molecular Tests More sensitive molecular tests can detect parasite DNA, providing faster and accurate diagnosis. Rapid Diagnostic Tests Rapid diagnostic tests (RDTs) are available for quick and convenient detection of malaria antigens.

6. Treatment and Management of Vivax Malaria 1 Quinine An antimalarial drug used to treat acute symptoms of malaria. 2 Primaquine Used to prevent relapses by eliminating the hypnozoite stage. 3 Supportive Care Providing hydration, managing fever, and addressing complications.
