N. fowleri is a free-living amoeba (“amoeba” is a catch-all time period for a lot of microbes, outlined by their means to shapeshift into completely different kinds and their finger-like projections used for motion, referred to as pseudopods). It mostly hangs round in heat our bodies of freshwater or the encircling soil. Ordinarily, the amoeba solely feeds off micro organism, and easily swallowing water containing it doesn’t harm us. But if N. fowleri finds its approach into the human mind, it develops a starvation for sure forms of cells and triggers an brain-destroying an infection generally known as naegleriasis, or main amoebic meningoencephalitis (PAM).
