Head Louse, Sem
Photograph - Photograph
Head louse. Coloured scanning electron micrograph (SEM) of a head louse (Pediculus humanus capitis) clinging to a human hair. Head lice measure 2-3 millimetres in length. They live in the hair on the head and suck blood from the scalp, causing intense itching. The itching provokes scratching, which can lead to scalp inflammation or dermatitis. Treatment is with medicated shampoo. Magnification x40 when printed at 10 centimetres wide.
