The brain-eating amoeba is a species that is known as the Naegleria fowleri. The Naegleria reproduces by cell division. When conditions are not right, the amoeba becomes an inactive cyst. When conditions are favorable, the cysts turn into trophozoites which are the feeding form of the amoeba.
They are found in warm water, mud puddles, hot springs, and other geothermal water sources, aquariums and in warm, slow-flowing rivers, especially those with low water levels. According to the WebMd, it cannot be found in swimming pools and salty water.
People who are mostly infected with brain amoeba get it from diving, water skiing, or doing water sports activity where water gets forced into the nose. Once it is in the nose, the amoeba travels through the olfactory nerve and passes into the frontal lobe of the brain.
The symptoms include; headache, fever, stiff neck, loss of appetite, vomiting, seizures, and coma.
Studies show that 60 percent of infants are the ones highly affected at the age of 13 and below. Eight out of ten men are also known to be exposed to this amoeba.
