OBJECTIVES Head lice (Pediculus humanus capitis) are a major irritant to children and their parents around the world. Each year millions of children are infested with head lice, a condition known as pediculosis, which is responsible for tens of millions of lost school days. Head lice have evolved resistance to many of the currently used pediculicides; therefore, an effective new treatment for h...

Growing patterns of pediculocidal drug resistance towards head louse laid the foundation for research in exploring novel anti-lice agents from medicinal plants. In the present study, various extracts of Pongamia pinnata leaves were tested against the head louse Pediculus humanus capitis. A filter paper diffusion method was conducted for determining the potential pediculocidal and ovicidal activ...

This paper presents and discusses archaeological samples of Pediculus humanus capitis nits/eggs in Arica, northern Chile, dating between 2000 B.C. and A.D. 500. Eight samples of nits/eggs taken directly from seven mummified bodies of both the valley and the coast of Arica, were collected and studied. Samples were analysed with scanning electron microscopy (SEM), uncoated, using low and variable...

1. Introduction. Let J be a closed linear interval ao^tSfo. Let r(/) = (#(/), y(t) } z(t)), tSI, represent a vector function whose three components x(t), y(i) t z(t) are of bounded variation and continuous on I. This vector function determines in Euclidean 3-space a curve x~x{t), y~y(t), z=*z(t) whose length we denote by LQç). By convergence in length of a sequence of such vector functions $ n ...

Several studies have documented the presence of Acinetobacter baumannii, a known multi-drug-resistant pathogen, in human head louse, Pediculus humanus capitis. Since no reports from countries Latin America been published, aim present study was to determine whether A. baumannii lice specimens collected this geographic region. Head Argentina, Colombia, and Honduras were analyzed. PCR assays perfo...

The increasing resistance of head lice Pediculus humanus capitis to many drugs has highlighted the need for new alternatives control in adults. effect two types extracts (aqueous and alcoholic) Citrullus colocynthis fruit on adult was tested vitro. results showed that alcoholic extract with a concentration 20% similar efficacy killing Natroba 9% w/w, values ranging between 87% 98% within 18 min...

A study of head lice infestations among young people, adults and elderly individuals was conducted from August 2010 to July 2013 in Manaus, AM, Northern Brazil. Hair samples collected from 1,860 individuals in 18 barber shops and beauty parlors were examined for the ectoparasite. The occurrence of pediculosis and its association with factors, such as sex, age, ethnicity, hair characteristics an...
