What's eating you? head lice (Pediculus humanus capitis).
The head louse (Pediculus humanus capitis) is a blood-sucking arthropod of the suborder Anoplura. Infestation continues in epidemic proportions in children of all socioeconomic groups. Although not implicated as a disease vector, infestation can lead to considerable distress, missed days of school, and secondary infections. Pyrethroids are recommended for treatment, but resistance is common. Ne...
متن کاملIsoenzymes of human lice: pediculus humanus and P. capitis.
Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.S.A.) and the head louse (P. capitis DeGeer from France, Madagascar, Mali & Senegal) were compared. Only esterase two e...
متن کاملGeographic distributions and origins of human head lice (Pediculus humanus capitis) based on mitochondrial data.
Human head lice (Pediculus humanus capitis) are subdivided into 3 deeply divergent mitochondrial clades (Clades A, B, and C), each having unique geographical distributions. Determining the evolutionary history and geographic distribution of these mitochondrial clades can elucidate the evolutionary history of the lice as well as their human hosts. Previous data suggest that lice belonging to mit...
متن کاملPotential role of head lice, Pediculus humanus capitis, as vectors of Rickettsia prowazekii
Since the pioneering work of Charles Nicolle in 1909 [see Gross (1996) Proc Natl Acad Sci USA 93:10539–10540] most medical officers and scientists have assumed that body lice are the sole vectors of Rickettsia prowazekii, the aetiological agent of louseborne epidemic typhus (LBET). Here we review the evidence for the axiom that head lice are not involved in epidemics of LBET. Laboratory experim...
متن کاملEx Vivo Development of Eggs from Head Lice (Pediculus humanus capitis)
Background: Data on ovicidal activity of pediculicides are essential to determine the efficacy of commercial products, and to define application schemes. We present an adaptation of historical methods for rearing head lice, and describe their development ex vivo. Methods: Adult head lice were collected and fed on volunteers to obtain fertile eggs of known age. Two methods of feeding were applie...
