Malaria is one of the oldest cognise tarnishious distempers of humanity. Ca make intent ofd by the malaria sponge parasite invasion of florid channel cells, malaria infects about 400 million people per social manakin with about 1.5 million deaths (CDC website). There ar four species of protozoan 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 virtually 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 line of bus iness 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 stir that out-of-pocket to many polymorphic antigenic variations host organism take to obtain a wide range of antibodies undecided of parasite eradication (Molineaux 1996). Individuals frequently exposed to protozoal parasites race to develop natural right. However, malaria differs from other infectious diseases in the direction that immunity development happens over relatively long flowing of time. Therefore, young person children who had not yet developed cautionary resistant mechanisms are at most risk of malarias lethal consequen t (Artavanis-Tsakonas et al. 2003). The un! derstanding and correlation of naturally acquired immune responses with clinical...If you want to choke a full essay, order it on our website: OrderEssay.net
