A parasitic worm 'shot-gunning' the brains of U.S. moose could be causing population decline, a new study found.The worm, named Elaeophora schneideri, has been infesting the animals' brains and causing severe symptoms, the research said. The parasite can severely disrupt a moose's circulation system, leading to blindness, ear damage and often death.Moose populations across some areas of North America have been declining in recent years.
'The microfilaria are just scattered throughout their brains, and even though the damage from each is miniscule, they're basically shot-gunning the whole brain,' Kyle Taylor, a pathologist at Washington State University's Animal Disease Diagnostics Laboratory said in a statement.
