Head louse, SEM

Videonummer 11921608
Head louse. Coloured scanning electron micrograph (SEM) of the head of a head louse (Pediculus humanus capitis). Its mouthparts are at centre. 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.
