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...

Whether people can become infected by head lice transferring from inanimate objects is a topic of controversy. This paper reviews the evidence available from experimental studies in controlled laboratory experiments and data from field studies. The weight of evidence appears to be against transmission from inanimate objects being significant, and the promotion of inanimate objects that play an ...

BACKGROUND Acinetobacter baumannii has previously been detected and genotyped in human body lice. The objectives of this study were to determine the presence of this bacterium in head and body lice collected from healthy individuals in Ethiopia by molecular methods and to characterize the genotype. METHODS Human lice from locations at different altitudes in Ethiopia were screened for the pres...

BACKGROUND Head louse infestations are prevalent worldwide. Over the past 20-25 years, 15-20% of all children in Israel between 4 and 13 years of age have been infested with head lice. This is mainly due to the existence of ineffective pediculicides on the market. OBJECTIVE To examine the pediculicidal efficacy and safety of a natural remedy ("Chick-Chack") and to compare it in an open clinic...

Pediculosis capitis is an infestation of Pediculus humanus var. Capitis or commonly called head lice on the hair and scalp humans. The disease has become endemic worldwide both in developed developing countries, with most infestations occurring school-age children. In Indonesia alone cases pediculosis from 2016 to 2019 are still widely found a percentage that high for example provinces Aceh, Pe...

Raptorial birds harbor a variety of ectoparasites and the mayority of them are host specific. The aim of this study was to identify the ectoparasites of captive birds of prey from Mexico, as well as to verify their impact in the health of infested birds. Raptorial birds were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La ...

Pruritic behaviour and deranged fleece are often used as indicators of sheep louse infestation but the exact relationship between infestation and the observation of signs of pruritus was unclear. Two studies were conducted to examine this association. In the first, 24 castrate Merino sheep were randomly assigned to six pens in groups of four and the sheep in three pens infested with 10 lice eac...

Because topical compounds based on insecticidal chemicals are the mainstay of head lice treatment, but resistance is increasing, alternatives, such as herbs and oils are being sold to treat head lice. To test a commercial shampoo based on seed extract of Azadirachta indica (neem tree) for its in vitro effect, head lice (n=17) were collected from school children in Australia and immersed in Wash...
