Permethrin-resistant human head lice, Pediculus capitis, and their treatment.
OBJECTIVE To compare the pediculicidal activity of Ovide lotion and its active ingredient, 0.5% malathion, with Nix and its active ingredient, 1% permethrin, in permethrin-resistant head lice. DESIGN In vitro pediculicidal product and active ingredient comparison. The presence of knockdown resistance-type mutations (T929I and L932F) was validated by DNA sequencing. SETTING University of Mas...
متن کاملBioactivity of Argentinean Essential Oils Against Permethrin-Resistant Head Lice, Pediculus humanus capitis
Infestation with the head louse, Pediculus humanus capitis De Geer (Phthiraptera: Pediculidae), is one of the most common parasitic infestation of humans worldwide. Traditionally, the main treatment for control of head lice is chemical control that is based in a wide variety of neurotoxic synthetic insecticides. The repeated overuse of these products has resulted in the selection of resistant p...
متن کاملWhat's eating you? head lice (Pediculus humanus capitis).
The head louse (Pediculus humanus capitis) is a blood-sucking arthropod of the suborder Anoplura. Infestation continues in epidemic proportions in children of all socioeconomic groups. Although not implicated as a disease vector, infestation can lead to considerable distress, missed days of school, and secondary infections. Pyrethroids are recommended for treatment, but resistance is common. Ne...
متن کاملIsoenzymes of human lice: pediculus humanus and P. capitis.
Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.S.A.) and the head louse (P. capitis DeGeer from France, Madagascar, Mali & Senegal) were compared. Only esterase two e...
متن کاملGeographic distributions and origins of human head lice (Pediculus humanus capitis) based on mitochondrial data.
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...
