Another life was claimed by the deadly brain-eating amoeba called Naegleria fowleri.

According to public health officials, three people are now dead. The last one was a man from Louisiana who is in his early 20s who died after rinsing his sinuses with tap water.

News of his death comes following the two other highly-publicized fatalities of a 9-year-old Virginia boy and a 16-year-old Florida girl. Those two died after contracting meningoencephalitis following swims in stagnant water where the killer bug, known as Naegleria fowler, is thought to thrive.

Naegleria fowleri is a free-living excavate form of protist typically found in warm bodies of fresh water, such as ponds, lakes, rivers, and hot springs. It is also found in soil, near warm water discharges of industrial plants, and minimally chlorinated swimming pools in an amoeboid or temporary flagellate stage. There is no evidence of this organism living in ocean water. It belongs to a group called the Percolozoa or Heterolobosea. Although not a true amoeba, the organism is often referred to as an amoeba for convenience.
