• body
  • Head lice (Pediculus humanus capitis) are not known to be vectors of diseases, unlike body lice (Pediculus humanus humanus), which are known vectors of epidemic or louse-borne typhus (Rickettsia prowazekii), trench fever (Rochalimaea quintana) and louse-borne relapsing fever (Borrelia recurrentis). (wikipedia.org)
  • Humans are the only known host of this parasite, although it is more closely related to the louse parasites in other primate species, than are human head or body lice which probably evolved from it as the "original" louse infestation of humans. (wikipedia.org)
  • hair
  • Those of African descent rarely suffer infestation due to differences in hair texture. (wikipedia.org)
  • To diagnose infestation, the entire scalp should be combed thoroughly with a louse comb and the teeth of the comb should be examined for the presence of living lice after each time the comb passes through the hair. (wikipedia.org)
  • The pubic or crab louse (Pthirus pubis) is a parasitic insect which spends its entire life on human hair and feeds exclusively on blood. (wikipedia.org)
