And just so no one freaks out here is some information (from Web MD) on the Amoeba:
Amoebas are single-celled organisms. The so-called brain-eating amoeba is a species discovered in 1965. It's formal name is
Naegleria fowleri. Although first identified in Australia, this amoeba is believed to have evolved in the U.S. There are several species of Naegleria but only the fowleri species causes human disease. There are several fowleri subtypes. All are believed equally dangerous. N. fowleri is microscopic: 8 micrometers to 15 micrometers in size, depending on its life stage and environment. By comparison, a
hair is 40 to 50 micrometers wide. Like other amoebas, Naegleria reproduces by cell division. When conditions aren't right, the amoebas become inactive cysts. When conditions are favorable, the cysts turn into trophozoites -- the feeding form of the amoeba.
Where Are Brain-Eating Amoebas Found?
Naegleria loves very warm water. It can survive in water as hot as 113 degrees Fahrenheit.
These amoebas can be found in warm places around the globe. N. fowleri is found in:
- Warm lakes, ponds, and rock pits
- Mud puddles
- Warm, slow-flowing rivers, especially those with low water levels
- Untreated swimming pools and spas
- Untreated well water or untreated municipal water
- Hot springs and other geothermal water sources
- Thermally polluted water, such as runoff from power plants
- Aquariums
- Soil, including indoor dust
Naegleria can't live in salt water. It can't survive in properly treated swimming pools or in properly treated municipal water. Most cases of N. fowleri disease occur in Southern or Southwestern states. Over half of all infections have been in Florida and Texas.
How Frequently Do People Get Infected by a Brain-Eating Amoeba?
Even though N. fowleri amoebas are relatively common, they only rarely cause
brain disease. N. fowleri disease is known as primary amoebic meningoencephalitis (PAM). It occurs from zero to eight times a year, almost always from July to September. It's considered a rare infection. But some cases may be unreported. A study in Virginia that looked at more than 16,000 autopsy records from patients who died of
meningitis found five previously unreported cases of PAM. Studies show that many people may have antibodies to N. fowleri. That suggests that they became infected with the amoeba but that their immune systems fought it off. It's not at all clear whether N. fowleri is a rare infection that always causes PAM and is almost always fatal, or a more common infection that only sometimes causes PAM. In a 2009 study, CDC researchers suggested that the common finding of antibodies to the amoeba in humans and the frequent finding of N. fowleri in U.S. waters indicates "that exposure to the amoeba is much more common than the incidence of PAM suggests."
