Project Flashknife parasite

Acrobacteria neurophaga (literally "brain-eating high bacteria"), commonly known as the Project Flashknife parasite, was a parasitic bacterium from an unknown planet. It specialized in feeding on the neurons (brain cells) of sentient species, causing a rare form of encephalitis. The Project Flashknife parasite could feed on the neurons of almost any sentient species, withhthe notable exception of the Nautolans. Scientists have determined that the parasite does not last for a long period of time in the brain of a Nautolan, but they have not yet determined the reason.
