3. Pediculosis Pediculosis is an infestation of lice-blood feeding ectoparasitics insects of the order Phthiraptera . The condition can occur in almost any species of warm-blooded animal ( i.e,mammals and birds), including humans.

4. Classification Pediculosis may be divided into the following types. Pediculosis capitis (Head lice infestation) Pediculosis corporis ( Pediculosis vesitmenti , Vagabond’s disease) Pediculosis pubis (Crabs)

5. 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. The use of a louse comb is the most effective way to detect lice. The most common symptom of lice infestation is pruritus (itching) on the head which normally intensifies 3 to 4 weeks after the initial infestation. The bite reaction is very mild and it can be rarely seen between the hairs

6. Treatment There are number of treatment modalities that can be employed with varying degrees of success. These methods includes chemical treatment, natural products, combs, shaving, hot air and silicone-based lotions. Cattle infested with bovine pediculosis are generally treated chemically, by drugs.
