MALARIA, ILLUSTRATION
The cycle paludism The transmission plasmodium parasite source paludism is made via compulsory vector the female anopheles mosquito The cycle biological the parasite consists phase sexed reproduction carryied out in the organism the mosquito asexual phase within the human body When female anophele mosquito stings individual affected by the disease it aspirates few microliters blood bearer the parasite During the sting another person it then transmits the parasite existing in those salivary glands under peculiar form the sporozoites The sporozoites injected in the blood will reach the liver the individual in few minutes infect its hepatocytes in which they will differentiate into another parasitic form the schizontes After few days divisions the mature schizontes release hepatic cells hundred thousands merozoites in the blood circulation by burst where they infect the red blood cells Within these red blood cells the merozoites will multiply leading to burst the red blood cells releasing merozoites again more numerous that will reinfect the red blood cells .. These cycles infections parasitic releasing are at the origin cyclic fever fits characteristics the disease Certain the merozoites released will differentiate into sexual form parasite the male female gametocytes that gather in cluster into the blood During the sting the individual impaludé by another female anophele the male female gametocytes are ingested by the mosquito In the stomach the insect the gametocytes will then differentiate into male female gametes ; their fertilization donnera zygote then oocyst producing sporozoites These migrate in the salivary glands the mosquito will be injected to new human victim At the center the illustration there is the map the regions in the world where paludism strikes either under endemic or sporadic form It strikes in tropical subtropical countries Africa Asia Latin America.
