Malaria is one of the oldest cognise tarnishious distempers of humanity. Ca make aim ofd by the malaria sponge parasite invasion of florid melodic line cells, malaria infects about 400 million people per social var. with about 1.5 million deaths (CDC website). There ar four species of protozoan parasites that are responsible for the infection: malaria parasite falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. With the exception of the last one, which may affect roughly 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 slant m enses 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 intimate that out-of-pocket to many polymorphic antigenic variations host beingness take to obtain a wide range of antibodies equal to(p) of parasite eradication (Molineaux 1996). Individuals frequently exposed to protozoal parasites work to develop natur al right. However, malaria differs from oth! er infectious diseases in the commission that immunity development happens over relatively long plosive consonant of time. Therefore, young person children who had not yet developed evasive tolerant 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
