For Reals... Brain Eating Zombies

i-a520510366c8e47bb8487bb2d79ded12-amoeba_braineating.jpgOk... maybe not for real reals but there are some brain eating amoebas taking over the world. Ok maybe they're not taking over the world but they really (for real this time!) have killed a few people.
According to the AP:

A killer amoeba living in lakes enters the body through the nose and attacks the brain where it feeds until you die.
Even though encounters with the microscopic bug are extraordinarily rare, it's killed six boys and young men this year. The spike in cases has health officials concerned, and they are predicting more cases in the future.

Panic!!! Don't swim in lakes! You will die! Die I tell you! Die!

In another case of TV shows being prescient, abuzz here at other Scienceblogs is this story, which sounds like a bad B movie: " 6 die from brain-eating amoeba in lakes." The amoeba in question is a species of naegleria, which was featured on the medical drama House last year. According to the…

First question: Where are these located? something tells me they are not located in industrial nations.

Second question: When the article says "feeding" are the eating proteins in the brain, and if so, can they be modified to only eat b-amyloid and get rid of alzheimers?

third question: Why have I never heard of the coolest bacteria ever?
