Head lice in human hair
Référence de la vidéo 11933099
| Head lice (Pediculus humanus capitis) clambering through human hair. Head lice are wingless parasitic insects, up to 3mm long, that spend their entire lives on the scalps of their human hosts. They feed exclusively on blood, which they suck from the skin using their sharp piercing mouthparts. Head lice, unlike other lice, are not vectors for any disease, and infestation is generally harmless, if not exactly desirable. The dead or empty eggs of head lice, which are attached to hair shafts, are colloquially known as its"". The presence of nits is a common condition, especially in children, and is often aggressively targeted in schools." | |
