In reviewing the current extent and epidemiology of louse infestations in human populations and between host and another, it is accepted that is infested by two species of lice/ of which consists of two subspecies (Busvine, 1976). The two species Pthirus pubis, the crab louse, andiPediculus humanus, the human louse, the latter with its two subspecies, P. h. capitis, the head louse, and P. h. hu...
The mainstays of treatment of body-louse infestation in humans in a community setting are insecticides and the removal of infested clothing. We report here the dramatic effect that 3 doses of oral ivermectin (12 mg each), administered at 7-day intervals, have in reducing the total number of body lice in a cohort of homeless men from a shelter in Marseilles, France. We identified a baseline tota...
BACKGROUND Body louse or head louse? Once removed from their environment, body and head lice are indistinguishable. Neither the morphological criteria used since the mid-18th century nor the various genetic studies conducted since the advent of molecular biology tools have allowed body lice and head lice to be differentiated. In this work, using a portion of the Phum_PHUM540560 gene from the bo...
To determine the presence of Bartonella quintana in head and body lice from persons in different locations in Ethiopia, we used molecular methods. B. quintana was found in 19 (7%) genotype C head lice and in 76 (18%) genotype A body lice. B. quintana in head lice was positively linked to altitude (p = 0.014).
Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540 blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...
UNLABELLED The incidence of pubic lice infestations is estimated to be between 1.3% and 4.6%, with an average incidence of 2% worldwide. It is also estimated that 70% to 80% of adults now remove pubic hair in part or entirety, using a variety of methods. It is hypothesized that the destruction of this pubic hair habitat may account for the falling incidence of pubic lice and may possibly lead t...
Aims: Pediculosis Capitis is one of the important health issues in students, which causes physical, social, and mental complications. This study was conducted with the aim of investigating the preventive behaviors against head lice infestation among female primary school students at Eyvan, Iran in 2016. Materials and Methods: The present study was a descriptive-analytic study performed on 157 ...
BACKGROUND Head lice, Pediculus humanus capitis, occur in four divergent mitochondrial clades (A, B, C and D), each having particular geographical distributions. Recent studies suggest that head lice, as is the case of body lice, can act as a vector for louse-borne diseases. Therefore, understanding the genetic diversity of lice worldwide is of critical importance to our understanding of the ri...
