Human head lice (Pediculus capitis) infest people worldwide and are most prevalent in children, the aim of this study was to determine the socioeconomic status of the family and hygienic practices in the home on prevalence of head lice infestation in children. The prevalence was investigated among 192 houses in Gaza city with 608 children. The hair was examined for head louse infestation. A tot...

The embryonic development of human lice was evaluated according to the changes in the morphology of the embryo observed through the transparent chorion. Based on ocular and appendage development, three stages of embryogenesis were established: early, medium, and late. Influence of temperature and relative humidity (RH) on the laboratory rearing of Pediculus humanus capitis eggs was assessed. Th...

The possibility of spreading by migration, colonizing new spatial domains suitable for development and reproduction, can substantially relieve a biological population from the risk of extinction. By means of a realistic computational model based on empirical data, we study this phenomenon for the human head louse, Pediculus humanus capitis. In particular, we show that a lice colony infesting a ...

Head lice (Pediculus humanus capitis) are not a significant public health concern but elicit great alarm among parents. The investigators host information websites through which they field several hundred queries annually. This study investigated the experience of those treating head lice infections focusing on control difficulties. A short web-based questionnaire (available August, 2006 and Fe...

Received: December 2011, Accepted: September 2012 Background: Head lice infestation is one of the most common parasitic infections with a long history in the world. The purpose of this study was to determine the prevalence of head lice infestation among 3-6 years old children going to nursery schools in Kashan, Iran in 2009. Materials and Methods: This cross-sectional study was performed on 120...

background: head lice infestation caused by pediculus humanus var capitis ( pediculus capitis ) is a worldwide public health concern that affects mostly school aged children. this descriptive, analytical study was carried out in 2008 to determine the prevalence of pediculosis capitis and some risk factors among primary-school pupils in bahar, hamadan province, iran. methods: we selected 900 pup...

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...
