Amoeba is a microscopic single-celled parasite which don’t have a definite shape. Its formal name is "Naegleria fowleri". It was first discovered in 1965 in Australia, but now Amoeba is believed to be evolved in Pakistan, US and some other parts of Asia as well. These Amoeba parasites are usually found in warm bodies of fresh water for eg. Lakes, rivers, ponds and hot springs. It can also be found in warm water discharged by industrial plants, non-chlorinated swimming pools and soil as well. Although it cannot be found in salty water such as in seas and oceans as well as in chlorinated swimming water. Naegleria fowleri is a heat loving organism. It can grow best at high temperatures up to 46 degree Celsius and can survive longer at high temperatures. That's the reason that Amoeba is likely to be found in warm water bodies.
