MALARIA P. falciparum - Pf P. vivax -Pv P. ovale - Po P. malariae - Pm causative agent = Plasmodium species 4 human Plasmodium species P. falciparum - Pf P. vivax -Pv P. ovale - Po P. malariae - Pm

Alternative names: · Quartan malaria · Falciparum malaria · Black water fever · Tertian malaria

A bite from an infective female Anopheles mosquito. Anopheles must be infected through a previous blood meal taken on an infected person to transmit malaria

Life Cycle transmitted by Anopheles mosquitoes sporozoites injected with saliva sporozoites invade liver cells undergo an asexual replication 1000-10,000 merozoites produced

Infective form: Sporozoite Period of one erythrocytic stage: P.V 48h; P.M 72h; P.F 36-48h

Scanning electron micrograph of Plasmodium-infected red blood cells Scanning electron micrograph of Plasmodium-infected red blood cells. One cell has burst open, releasing merozoites

Physical symptoms: Fever: Fever can be very high from the first day. Temperatures of 40°C and higher are often observed. Fever is usually continuous or irregular. Classic periodicity may be established after some days. Hepatomegaly: The liver may be slightly tender. Splenomegaly: Splenomegaly takes many days, especially in the first attack in nonimmune children. In children from an endemic area, huge splenomegaly sometimes occurs.

Anemia: Prolonged malaria can cause anemia, and malarial anemia causes significant mortality. Jaundice: With heavy parasitemia and large-scale destruction of erythrocytes, mild jaundice may occur. This jaundice subsides with the treatment of malaria. Dehydration: High fever, poor oral intake, and vomiting all contribute to dehydration.

Ring stage of malaria

Diagnosis 1. Parasitological diagnosis: Parasite; Species; Density Thin blood films (species identification) Thick blood films 2. Immuno-diagnosis Specific antibody detection Antigen detection Specific DNA or RNA detection

Treatment Chlorquine and quinine----anti- erythrocytic stage drugs. Primaquine and pyrimethamine ----anti-exoerythrocytic stage drugs.
