Hi, Ferial Amin, This is not a species but group of hardly differed species even of separate classes members. These include free-living amoeba that live in natural and artificial water and soil. Once in the human body, they can cause severe inflammation of the CNS (meningoencephalitis). The most dangerous representatives of two genera: Naegleria and Acanthamoeba. Amoeba of the Limax group can parasitize humans, monkeys and rodents. The most virulent is Naegleria. Human infection occurs through the mucosa of the nasopharynx while bathing in open ponds and basins, through water when washing (Naegleria), cysts with dust (Acanthamoeba). In the nasal cavity amoeba multiply and in the course of the olfactory nerve penetrate into the brain. Pathogenic action: Mechanical – destroying the gray matter of the cerebral hemispheres of the brain and its membranes). Toxic-allergic – poisoning of the organism by waste products. As a result of violation of the integrity of cells and the membranes of the brain develop inflammation – meningoencephalitis. The incubation period is 4-7 days.
I hope it help,
Andrey
