Isoenzymes 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 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 کاملThe Experimental Infection of the Human Body Louse, Pediculus Humanus Corporis, with Murine and Epidemic Louse-borne Typhus Strains
Experiments are described which demonstrate that human body lice (Pediculus humanus corporis), were infected experimentally with murine and epidemic louse-borne strains of typhus fever by feeding on suitably prepared rabbits. Details of the two methods of infection, the "bleb technique" and the "I.V. technique," are presented. It is concluded that the experimental infection of human lice with t...
متن کاملWhat'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...
