MALARIA FEVER

A FEMALE anopheles mosquito


MALARIA FEVER 


   This is the commonest endemic disease in the tropics. It is caused by Plasmodium infection as a result of mosquito bite. It is the commonest cause of fever in our environment. The female anopheles mosquito is the vector. 
There are four species of plasmodium namely ; 
1. Plasmodium Falciparium ; 
3. Plasmodium Ovale ; 
2. Plasmodium Malaria ; 
4. Plasmodium Vivax. 
   If a female anopheles mosquito bites and suck the blood of a person having malaria fever, the mosquito becomes infected. The male and female gamatecytes in the infected blood grow and mature in the 
gastrointestinal tract of the mosquito. The male gamete known as the microgamate exflagellates. Fertilization then occur to produce a zygote. The zygote progressively develops into 00 kinete, young oocyte 
and segmenting oocyte. Theoocyte rupture to release sporozoites into the salivary gland of the mosquito. 
    Should this mosquito bite another person, it deposits the sporozoites into the person's blood stream. These sporozoites move from the blood into the liver within thirty minutes. Here they undergo development and break up haemoglobin to get oxygen and are therefore pigmented. These pigmented sporozoites are called merozoites. From the liver, these merozoites are released into the 
blood stream. Most of these merozoites invade the red blood cells and some can re-infect the liver in a secondary exoerythrocytic cycle, Development of the merozoites in the red blood cell produce 
trophozoites. Further multiplication of the trophozoites give rise to schizonts. Schizonts rupture to produce more merozites. These merozites differentiate into immature gamates which eventually 
mature to male and female gaments. Check out more.
