Background: Head louse infestation is highly common in collective centers such as schools, garrisons and campuses. This study was done to determine the prevalence and risk factors associated with Pediculus humanus capitis in primary school girls in Qom Provincecentral Iran. Materials and Methods: This descriptive –analytic study was conducted among 1,725 feminine primary students from 89 sch...

The prevalence of head lice (Pediculus humanus capitis) is one the most common infections at all ages, especially among students, and widespread worldwide.

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...

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...

Two genera of lice parasitize humans: Pthirus and Pediculus. The latter is of significant public health importance and comprises two ecotypes: the body louse and the head louse. These ecotypes are morphologically and genetically notably similar; the body louse is responsible for three infectious diseases: Louse-borne epidemic typhus, relapsing fever, and trench fever.
