Understanding the evolution of parasites is important to both basic and applied evolutionary biology. Knowledge of the genetic structure of parasite populations is critical for our ability to predict how an infection can spread through a host population and for the design of effective control methods. However, very little is known about the genetic structure of most human parasites, including t...

conclusions the results showed that the prevalence of pediculosis among the glogah county primary school students was less than the average percentages observed in other students inside and outside of iran. results based on a total of 300 pupils, 17 of them (5.7%) were infested with pediculus capitis. the prevalence rate was 6.8% in the boys and 4.8% in the girls, while the rate of infestation ...

Chemical, physical, and mechanical methods are used to control human lice. Attempts have been made to eradicate head lice Pediculus humanus capitis by hot air, soaking in various fluids or asphyxiation using occlusive treatments. In this study, we assessed the maximum time that head lice can survive anoxia (oxygen deprivation) and their ability to survive prolonged water immersion. We also obse...

We read with interest but question the recent article by Sasaki et al. (2006) that reported the molecular detectionbynestedpolymerase chain reaction (PCR) of the agent of trench fever, Bartonella quintana, in humanbody louse,Pediculus humanus humanusL., the known vector, as well as in human head louse, Pediculus humanus capitis De Geer, all collected on Nepalese children. Head lice are widely d...

Twenty six male and female patients aged 5 to 17 years who had head lice infestation confirmed by eggs presence and received treatments with a single 200 mu/kg oral dose of ivermectin in open fashion. At day 14 after treatment, 20 responded to the treatment (77%), and 6 patients (23%) presented with a complete disappearance of eggs and all clinical symptoms. At day 28, 7 patients were healed (2...

In total, 2,408 primary school girls (6-14 yr old) in two districts within the Gaza Governorate were examined for the presence of head lice, Pediculus humanus capitis De Geer. The localities chosen for the study were the Old Gaza city and the rural village Jabalia. The rate of infestation with lice was 14.1%, and an additional 35% of girls had nits (eggs) only. The prevalence of louse infestati...

Essential oils have been widely used in traditional medicine for the eradication of lice, including head lice, but due to the variability of their constitution the effects may not be reproducible. In an attempt to assess the contribution of their component monoterpenoids, a range of common individual compounds were tested in in vitro toxicity model against both human lice (Pediculus humanus, an...
