Brain-eating amoebae can cause particularly harmful forms of encephalitis, and more than 95% of people who develop these rare but devastating infections die. Despite the high mortality rate, there is currently no single effective drug available to fight these microbes. Now, however, researchers have designed some new compounds that show promise in the laboratory as treatments, according to a report in ACS Chemical Neuroscience.
Naegleria fowleri and Balamuthia mandrillaris are two types of amoebae that can cause primary amoebic meningoencephalitis and granulomatous amoebic encephalitis. They are single-celled microorganisms that live in water and soil, and can enter the body through the nose or open wounds. These pathogens can then move to the central nervous system, where they destroy brain cells.
