Pediculosis means louse infestation partially or on whole body as ectoparasite (Psora).
Lice are prehistorical with evidence of 10,000 years old fossils of louse eggs or nits.
The ectoparasite lice feed on human blood after piercing the skin and injecting saliva, which may cause pruritus due to allergic reaction (Psora). Lice crawl but cannot fly or hop.
Body louse infestation is also known as vagabond disease, and individuals who have an infestation for many years can develop a condition termed vagabond skin. The skin becomes thickened and darkened after years of bites and subsequent rubbing and excoriations (Psora/ Syphilis/ Sycosis).
The female head louse lays as many as 10 eggs, called nits, per 24 hours, usually at night. Egg and glue extrusion onto the hair shaft takes 16 seconds. Nits are typically located at the posterior hairline and postauricular areas. Nits are white and less than 1 mm long. Lice glue them at the base of the hair shaft. Nits are placed within 1-2 mm of the scalp, where the temperature is optimal for incubation. The immature lice, called nymphs hatch from the nits after 8-9 days, mature in 9-12 days, and become adults, living for about 30 days.
Cooler temperatures retard both hatching and maturation. Different species of lice have particular affinity for certain locations on the body of the host.
Lice move from person to person via close physical contact either directly or fomites like combs, brushes, clothes, hats, scarves, coats, linens etc. Overcrowding facilitates spread of lice (Causa occassionalis).
Species of louse may be-
The head louse, Pediculus humanus capitis, has an elongated body and narrow anterior mouthparts.
Head Louse and its nits
Body lice look similar but lay their eggs on clothing fibers instead of hair fibers. The body louse is larger than the head louse. Unlike the head louse and the pubic louse, the body louse does not live on the human body. Pediculus humanus corporis prefers cooler temperatures; it lives in human clothing, crawling onto the body only to feed, predominantly at night. Adult body lice can live up to 30 days but die within 1-2 days when away from the host and without blood meals.
The pubic louse, Pthirus pubis, is identified by its wide crablike body, hence, sometimes called “crabs”. Pubic lice live for approximately 2 weeks, during which time the females lay 1-2 eggs per day.
Their large claws enable pubic lice to grasp the coarser pubic hairs in the groin, perianal, and axillary areas. Heavy infestation with P pubis can also involve the eyelashes, eyebrows, facial hair, axillary hair, and, occasionally, the periphery of the scalp. Pubic lice are less mobile, mainly resting while attached to human hairs. They can crawl up to 10 cm/day. They cannot survive off the human host for more than 1 day.

Body Lice and their nits on clothing
Treatments are highly effective in killing nymphs and mature lice, but less effective in killing eggs. The following are the factors which are responsible for failure in lice treatment-
Papular urticaria (insect bite reactions) –multiple, erythematous, pruritic papules
Crab louse eggs on the eyelashes
Lice are vector of Rickettsia prowazeki for typhus, Bartonella quintana for trench fever and Borrelia recurrent for relapsing fever.
Lice may carry Staphylococcus aureus and group A Streptococcus pyogenes on their surface and transmit these coagulase-positive pathogens to humans.
These are also called hair casts and are ring like remnants of the inner root sheath of the hair follicle and are amorphous and freely moveable along the hair fiber.
It presents with erythema and scaling and affects the scalp, eyebrows, nasolabial folds, and central chest.
It presents with inflamed follicular papules and pustules, black crusts, and scarring. It is extremely pruritic.
These free-living primitive lice feed on decaying matter in leaves, old books, and animal habitats and may cause scalp infestation in children.
