from Texas invaded by microbe [theguardian.com]
"Texas officials have warned residents of some communities near Houston to stop using tap water because it might be tainted with a deadly brain-eating microbe.
Naegleria fowleri is a microscopic amoeba commonly found in warm freshwater and soil, according to the US Centers for Disease Control and Prevention. It usually infects people when contaminated water enters the body through the nose, from where it travels to the brain and can cause a rare and debilitating disease called primary amebic meningoencephalitis."
