Malaria

Malaria is one of the oldest cognise cloudious distempers of humanity. Ca make usage ofd by the malaria sponge parasite invasion of florid tear cells, malaria infects about 400 million people per social fall apart with about 1.5 million deaths (CDC website). There ar four species of protozoal parasites that are responsible for the infection: plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. With the exception of the last one, which may affect almost other primates, all malaria parasites use only humans as hosts. The disease is transmitted trough the bite of the female genus Anopheles mosquito. The parasites use only some of many species of this insect as a transmission vectors. After infection parasite enters the crinkle menses and migrates to the liver where it rapidly replicates. When the parasites mature, they leave the liver and infect red-faced blood cells. Mosquitoes become infected when they feed on infected people and the cycle continues. Described above, the facts characterize malaria as a disease with high specificity.

The specificity of the disease goes sink in hand with the high adaptation ability of the malaria parasites. Some studies pop the question that out-of-pocket to many polymorphic antigenic variations host being take to obtain a wide range of antibodies capable of parasite eradication (Molineaux 1996). Individuals frequently exposed to protozoal parasites scarper to develo p natural right. However, malaria differs f! rom other infectious diseases in the track that immunity development happens over relatively long extent of time. Therefore, young person children who had not yet developed evasive immune mechanisms are at most risk of malarias lethal consequent (Artavanis-Tsakonas et al. 2003). The understanding and correlation of naturally acquired immune responses with clinical...If you want to choke a full essay, order it on our website: OrderEssay.net
