Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia | 0.02 sec. |
louseParasitic insect that lives on mammals. It has a flat, segmented body without wings, and a tube attached to the head, used for sucking blood from its host. (Order Anoplura.) Some lice occur on humans, including the head louse (Pediculus capitis) and the body louse (P. corporis), a typhus carrier. Pediculosis is a skin disease caused by infestation of lice. Most mammals have a species of lice adapted to living on them. Biting lice belong to a different order of insects (Mallophaga) and feed on the skin, feathers, or hair. Each year 14 million children in the USA alone suffer from head lice. How to thank TFD for its existence?

With biting lice, the skin is irritated and itchy, causing the horse to rub and bite the infested areas. While there's not yet conclusive evidence that Damalina Cervicola causes DHLS, many biologists hypothesize that biting lice trigger a "severe hypersensitivity reaction" which "results in excessive licking and biting by the host animal," leading to removal of large patches of hair. Biting lice feed on particles of hair, scabs, and excretions from the skin. |
