louse

 [lows] (pl. lice)
any of various grayish, wingless insects parasitic on birds and mammals, including humans; they are usually one sixteenth to one sixth of an inch (0.15 to 0.4 cm) long. Lice are classified into two orders, Anoplura (the sucking lice) and Mallophaga (the bird lice or biting lice). The causal organisms of typhus, relapsing fever, trench fever, and other diseases are transmitted by the bites of lice. The most important species parasitic on humans are Pediculus humanus capitis, the head louse, which attaches itself to the hairs of the head; P. humanus corporis, the body or clothes louse; and Phthirus pubis, the crab louse, which lives in the pubic hair, eyelashes, and eyebrows. Endemics of head lice infestations occur most frequently in school children. Pubic lice are often sexually transmitted. Louse infestation is called pediculosis.

louse

pl. lice; a general name for various species-specific parasitic insects, the true lice, which infest mammals and belong to the order Phthiraptera. This is divided into two suborders, Mallophaga, the biting lice, and Anoplura, the sucking lice. They are grayish, wingless, dorsoventrally flattened, and vary in length from about 1.5 to 4 mm. They stimulate rubbing, scratching and restlessness, causing damage to fleece and loss of production. Heavy infestations with sucking lice may cause serious anemia. Louse infestation is also called pediculosis.
The term louse is also used loosely with respect to other external parasites, e.g. whale 'lice' are barnacles and small copepods.
