Boy’s death confirmed as first case of brain eating amoeba in tap water
Researchers have discovered the first confirmed case of someone contracting a deadly brain-eating amoeba known as Naegleria fowleri through tap water. Prior victims were infected after swimming in warm bodies of freshwater.
A study published this month in the journal Clinical Infectious Diseases reported that a 5-year-old Louisiana boy did, in fact, pick up the microorganism from tap water, possibly via a Slip n’ Slide. About two weeks later, he perished from an infection known as primary amebic meningoencephalitis (PAM).
Naegleria fowleri is called the brain-eating amoeba because it can digest neural tissues. Upon entering the body via the nasal passages, N. fowleri penetrates bone between the sinuses and the brain to form an infection, breaking down nerve cells in the process. Ensuing swelling of the brain occurrs, ushering in PAM, which is usually fatal. PAM kills up to eight people per year in the US, usually males with a median age of 12.
The Louisiana boy was taken to a hospital in July 2013 after he acquired a 104-degree Fahrenheit (40° C) fever and complained of a devastating headache, in addition to bouts of vomiting. Doctors later recorded two short “staring episodes,” in which the boy would gaze straight ahead for a few seconds without responding.
The infection, though, could not be identified or halted after several tests and antibiotics. The boy eventually developed seizures, and was declared brain dead. His family took him off life support five days after he entered the New Orleans hospital, according to Newsweek.
His was the first confirmed case to have been triggered by tap or faucet water, and not freshwater immersion, according to study author Jennifer Cope, a medical epidemiologist for the US Centers for Disease Control and Prevention (CDC).
Anyone who swims in lakes or uses a netti pot should read this. Use bottled water only in your netti pot. http://t.co/YHcZu2hGfN

Neti pots, or nasal rinses, have been associated with the microorganism as well, such as one case in the US Virgin Islands.
Louisiana has recently increased efforts to test for the amoeba while advising higher levels chlorine in its water treatment operations. The CDC has an emergency drug called miltefosine to combat PAM cases, though it is not commercially available.
Other studies are probing how N. fowleri becomes infectious.
“This is a free-living amoeba that doesn't have to infect anybody, it's perfectly happy feeding on bacteria,” Francine Marciano-Cabral, a microbiologist at Virginia Commonwealth University who is studying the microorganism, said to Newsweek. “What we want to find out is why in some people is it so pathogenic and deadly and what makes it that way?”
The reason Louisiana Gov. Jindal has been making such stupid comments lately? He drinks Louisiana tap water! http://t.co/FjeRW1pur2

Artist uses Brainwaves to Manipulate Water
Amazing geometrical water display of human emotions
South Korean Artist Lisa Park has come up with an interesting new art form. Her performance art, called Eunoia, meaning “Beautiful Thinking”, uses 48 pools of water, inspired by the 48 emotions, which react to emotional brainwaves transmitted from her body, and read by sensors. Linked up to an EEG brainwave detecting sensor which detects the brainwaves she is putting out in real time, and then broadcasts them as sound, she creates rippling movements in the different pools resulting in her unique art. In this way she makes an audio-visual representation of herself and her emotional state. Watch Lisa Park as she puts her inner struggles on display in a beautiful geometrical water display.
