Therefore it is placed in the group of which means interior amoebas usually found within vertebrates.
But under certain conditions it becomes pathogenic: starts swallowing or phagocyte cells of our body (such as erythrocytes), or begins to invade organs and tissues such as the liver or the intestine. It is only then that it causes the disease. http://www.reviewlization.com/
A can cause a simple dysentery (diarrhea) to the involvement of one organ or tissue.
It occurs worldwide and is usually associated with economic conditions and poor hygiene.
Why? For the simple fact that only handle eating amoeba cysts that contaminate water and food. But as these cysts will stop the water, contaminating it?
As required intestinal parasite of man, there is only one way to do it: feces.
When the sanitation and hygiene conditions of the population are poor, the possibility of water contamination by human feces increases.
This same water downstream can be used for irrigation of fruits and vegetables or even for direct human consumption. You could view the entire cycle?
Compounding the box, the cysts that will contaminate the environment are tough to top! They last on average 30 days in water, 12 days in fresh feces, 24 hours in breads and cakes and 20 hours in dairy (milk products)? But fortunately we can break this chain of transmission: simply that we can ensure minimum sanitation Basic to the people and provide them clean water, as the chlorine added to the treatment plants kills the cysts of this and other amoebas.
