Located in the Kingdom Protozoan Malaria is a parasitic mosquito born organism passed to humans by several species of the genus Anopheles and is responsible for about 220 million infections every year and 600,000- 1,200,000 deaths every year. The developing world is disproportionately affected which had led to some unique changes when dealing with infections such as drugs needing to be cheap, administered orally and stable at relatively high temperatures. However in keeping with the old saying prevention is better than cure many methods have been proposed and tested to control the mosquito vector that transmits malaria as supposed to treating the infect after it occurs. The life cycle of the malarial practice consists of a motile non sexually reproductive form termed a sporozoite making its way into the hosts blood stream via being bitten by a mosquito seeking a blood meal. From here it travels into the liver cells where it reproduces asexually to produce merozoites which infect red blood cells and metabolise haemoglobin. At this stage the parasites reproduces asexually to produce more merozoites which infect more red blood cells. At this stage some of the merozites develop into gametocytes which are immature gametes. When a mosquito bites the infected individual the gametocytes are taken up with the blood meal. In the mosquitos gut the gametocytes develop into mature gametes where they form a zygote -which is motile- that migrates to the salivary glands of the
