Body lice are disease vectors and can transmit pathogens that cause human diseases such as epidemic typhus, trench fever, and relapsing fever. [6] In developed countries, infestations are only a problem in areas of poverty where there is poor body hygiene, crowded living conditions, and a lack of access to clean clothing. [ 7 ]
Pediculosis corporis is caused by the body louse, Pediculus humanus humanus (syn. Pediculus corporis [citation needed]). The dark mass depicted inside the abdomen is a previously ingested blood meal.

Ticks and lice form another large group of invertebrate vectors. The bacterium Borrelia burgdorferi, which causes Lyme Disease, is transmitted by ticks and members of the bacterial genus Rickettsia are transmitted by lice. For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus.
Accordingly, the infestation with head lice is named pediculosis capitis, while this with body lice, pediculosis corporis. [ 1 ] [ 2 ] Although pediculosis in humans may properly refer to lice infestation of any part of the body, the term is sometimes used loosely to refer to pediculosis capitis , the infestation of the human head with the ...
Scientists have long debated whether human body lice might have helped drive the rapid spread of the bacteria responsible for the deadly plague in the Middle Ages, known as the Black Death ...
Humans host two species of louse—the head louse and the body louse are subspecies of Pediculus humanus; and the pubic louse, Pthirus pubis. The body louse has the smallest genome of any known insect; it has been used as a model organism and has been the subject of much research. Lice were ubiquitous in human society until at least the Middle ...
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.
The treatment of human lice is the removal of head lice parasites from human hair. It has been debated and studied for centuries. It has been debated and studied for centuries. However, the number of cases of human louse infestations (or pediculosis ) has increased worldwide since the mid-1960s, reaching hundreds of millions annually. [ 1 ]
