Pediculosis is an infestation of lice from the sub-order Anoplura, family Pediculidae. Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. Although pediculosis in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to pediculosis capitis, the infestation of the human head with the specific head louse. Classification
Pediculosis may be divided into the following types:: 446–8 
Pediculosis capitis (Head lice infestation)
Pediculosis corporis (Body louse infestation, also known as Pediculosis vestimenti, Vagabonds disease)
Pediculosis pubis (Pubic louse infestation, also known as phthiriasis)

Head lice
Presentation
Head-lice infestation is most frequent on children aged 3–10 and their families. Approximately 3% of school children in the United States contract head lice. Females aged 3–12 years are most commonly infested. Those of African descent rarely experience infestation due to differences in hair texture.Head lice are spread through direct head-to-head contact with an infested person. From each egg or "nit" may hatch one nymph that will grow and develop to the adult louse. Lice feed on blood once or more often each day by piercing the skin with their tiny needle-like mouthparts. While feeding they excrete saliva, which irritates the skin and causes itching. Lice cannot burrow into the skin. Diagnosis
To diagnose infestation, the entire scalp should be combed thoroughly with a louse comb and the teeth of the comb should be examined for the presence of living lice after each time the comb passes through the hair.
This is a significant problem, as it can cause weight loss of 55 to 75 pounds per animal. Some species of lice infesting cattle include the cattle biting louse (Bovicola bovis), the shortnosed cattle louse (Haematopinus eurysternus), the longnosed cattle louse (Linognathus vituli), and the little blue cattle louse (Solenopotes capillatus). Treatment
Cattle infested with bovine pediculosis are generally treated chemically, by drugs like ivermectin and cypermethrin. History
In the 15th century, topical mercury treatment was used to treat pediculosis. See also
