Initial symptoms appear in less than a week after infection and include fever, headache, nausea, stiffness in the neck, and vomiting. If water containing the amoeba enters the nose, the parasite can travel via the olfactory nerves, which are responsible for detecting odour molecules and transmitting them as signals to the brain. The amoeba also causes a whole host of other neurological symptoms and has a fatality rate approaching 100%. This parasite can cause a rare brain infection called meningoencephalitis, which causes severe brain inflammation. Naegleria fowleri – commonly known as brain-eating amoeba – is single-celled and free-living and thrives in warm bodies of water. Centers for Disease Control and Prevention, CC BY gingivalis colonises its host in different ways, including through ingesting contaminated food or breaks in the skin and is usually only discovered after death.īrain-eating amoeba under a microscope.

Human infection is rare and only affects those with compromised immune systems (for example cancer or HIV/AIDS patients) but the outcome is always fatal meningo-encephalomyelitis – an inflammation of the brain, spinal cord and their membranes. gingivalis is now detected worldwide and has reportedly caused neurological disease in horses in countries including the UK, Japan, Canada, US, and Iceland. This worm is generally harmless, but under certain conditions can infect humans and animals. Halicephalobus gingivalis is a soil-borne, free-living nematode. Here are five that, though still thankfully rare, have made an appearance in new places. The parasites, which can invade and damage vital body organs such as the brain, range from one-celled organisms to relatively large tape worms. Global events such as climate change and an international trade have caused a number of dangerous parasites to emerge in countries where they haven’t been found before.
