Brain-eating amoeba?

A rare brain-eating amoeba is responsible for at least 10 deaths in the Pakistani city of Karachi in recent months, health officials believe. The source of the parasite is not yet known, but it is thought victims may have been exposed to it when using water to rinse their nasal passages.
The amoeba, Naegleria Fowleri, lives in warm water and kills its victims by destroying brain tissue.
Does this mean that they could be Zombies?
