Naturally, the brain, or rather brain tissue, is not part of the food supply for Naegleria fowleri. But amoebas have a key difference. It must hijack the cellular machinery of a living cell in order to survive. These dwell nearly everywhere on Earth, from the bottom of the sea to inside other living organisms (such as plants and animals). Although scientists frequently refer to viruses as live or dead, in fact no virus is truly alive. This usually involves introducing some sort of disease-causing germ to an individual. cell: The smallest structural and functional unit of an organism. nucleus: Plural is nuclei.

Stinky success: Scientists identify the chemistry of B.O. If N. fowleri enter the body though the nose, they can travel to the frontal lobe of the brain and cause a serious infection. They can eat bacteria, algae or fungal cells. Amoebas eat using their pseudopodia. The amoeba can be found in water and prefers warm temperatures up to 113 degrees Fahrenheit. They can also be found in soil, and in extremely rare cases, in contaminated tap water or swimming pools that haven’t been properly chlorinated. The fatality rate is more than 97 percent, but again, infection is rare. This encloses the prey inside a new unit within the amoeba’s cell, where it gets digested. Untreated swimming pools and spas.
