Definition: A mastigophoran is a type of nematode that feeds on the skin and hair of its host. These parasites are known for their ability to cause severe allergic reactions in humans, including anaphylaxis. They feed on the epidermal cells of the skin, which can lead to inflammation, redness, and swelling. Mastigophorans also have a parasitic life cycle, where they lay eggs inside host tissues, causing damage and death.
