The body louse (Pediculus humanus humanus, also known as Pediculus humanus corporis) or the cootie is a hematophagic ectoparasite louse that infests humans. [1] It is one of three lice which infest humans, the other two being the head louse, and the crab louse or pubic louse.
Pediculus humanus is a species of louse that infects humans. It comprises two subspecies: [1] [2] Pediculus humanus humanus Linnaeus, 1758 – body louse; Pediculus humanus capitis De Geer, 1767 – head louse
The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. [1] Head lice are wingless insects that spend their entire lives on the human scalp and feed exclusively on human blood. [1] Humans are the only known hosts of this specific parasite, while chimpanzees and bonobos host a closely related species, Pediculus schaeffi.
For scientists interested in how humankind evolved and spread around the globe, the blood-sucking parasite — officially called Pediculus humanus — also contains a lode of genetic information ...

Head lice infestation, also known as pediculosis capitis, is the infection of the head hair and scalp by the head louse (Pediculus humanus capitis). [6] Itching from lice bites is common. [5] During a person's first infection, the itch may not develop for up to six weeks. [5] If a person is infected again, symptoms may begin much more quickly. [5]

Pediculus humanus is divided into two subspecies, Pediculus humanus humanus, or the human body louse, sometimes nicknamed "the seam squirrel" for its habit of laying of eggs in the seams of clothing, and Pediculus humanus capitis, or the human head louse. Pthirus pubis (the human pubic louse) is the cause of the condition known as crabs.
