  1. Malaria By: Keri Gregory

  2. What is Malaria??? Malaria is an infectious disease that is cause by a protozoan parasite.

  3. Plasmodium • Plasmodium is the name of the parasite that causes the disease Malaria. • The plasmodium parasite feeds off of red blood cells contents. Causing the red blood cell to eventually burst. • The plasmodium parasite enters the human though the bite of a Anopheles mosquito. • After the plasmodium parasite finishes its cycle in the human it can infect other mosquitoes that bite the infected human.

  4. Symptoms of Malaria • Fever • Chills • Headache • Sweats • Fatigue • Nausea and vomiting

  5. Life Cycle of Malaria

  6. Stages of Malaria • Stage 1: Anopheles mosquito inoculates sporozoites into the human host. • Stage 2: The sporozoites then infect liver cells of the host and mature into schizonts. • Stage 3: The schizonts rupture and release merozoites. • Stage 4: Merozoites travel through the blood stream to infect red blood cells.

  7. Stages of Malaria • Stage 5: In the red blood cells, the ring stage trophozoites mature into schizonts, which rupture releasing merozoites. • Stage 6: Some parasites differentiate into sexual erythrocytic stages (gametocytes). • Stage 7: Blood stage parasites are responsible for the clinical manifestations of the disease. • Stage 8: The gametocytes are then ingested by an Anopheles mosquito as it feeds on the infected host.

  8. Stages of Malaria • Stage 9: The parasites’ multiply in the mosquito which is known as the sporogonic cycle. • Stage 10: While in the mosquito's stomach, the microgametes penetrate the macrogametes generating zygotes. • Stage 11: The zygotes in turn become motile and elongated which invade the midgut wall of the mosquito where they develop into oocysts. • Stage 12: The oocysts grow, rupture, and release sporozoites , which make their way to the mosquito's salivary glands and then inoculation of the sporozoites into a new human host.
