PY - 2017 T2 - Harrison's Infectious Diseases, 3e AB - Ectoparasites include arthropods and creatures from other phyla that infest the skin or hair of animals; the host animals provide them with sustenance and shelter. The ectoparasites may penetrate within or beneath the surface of the host or may attach by mouthparts and specialized claws. These organisms may inflict direct mechanical injury, consume blood or nutrients, induce hypersensitivity reactions, inoculate toxins, transmit pathogens, and incite fear or disgust. Humans are the sole or obligate hosts for many kinds of ectoparasites and serve as facultative or paratenic (accidental) hosts for many others.
