| clinical update on resistance and treatment of pediculosis capitis. | the anatomy and physiology of head lice make them extremely adaptable to their human hosts but also difficult to eradicate. their coloring and small size make them difficult to see, and the larvae, or nymphs, have multiple exoskeletons for protection. when exposed to pediculicides, a nymph can shed its outer exoskeleton and receive only a sublethal dose. through natural selection, head lice have developed resistance to commonly used pediculicides, making it increasingly difficult to eliminate in ... | 2004 | 15515630 |
| overview: the state of head lice management and control. | head lice infestations affect millions of people in the united states. children become infested more often than adults and account for the largest percentage of infestations. head lice have not been shown to transfer disease, and they are not associated with serious morbidity. the most common effect of lice infestation is pruritus of the scalp with occasional cutaneous infection caused by scratching. nevertheless, many schools have "no-nit" policies, which require the dismissal of children from ... | 2004 | 15515629 |
| genetic analysis of lice supports direct contact between modern and archaic humans. | parasites can be used as unique markers to investigate host evolutionary history, independent of host data. here we show that modern human head lice, pediculus humanus, are composed of two ancient lineages, whose origin predates modern homo sapiens by an order of magnitude (ca. 1.18 million years). one of the two louse lineages has a worldwide distribution and appears to have undergone a population bottleneck ca. 100,000 years ago along with its modern h. sapiens host. phylogenetic and populatio ... | 2004 | 15502871 |
| acinetobacter baumannii in human body louse. | while we were isolating bartonella quintana from body lice, 40 acinetobacter baumannii strains were also isolated and genotyped. one clone was unique and the other was ampicillin susceptible. a. baumannii dna was later detected in 21% of 622 lice collected worldwide. these findings show an a. baumannii epidemic in human body lice. | 2004 | 15498175 |

| flying squirrels and their ectoparasites: disseminators of epidemic typhus. | information gathered during the past decade indicates that the eastern flying squirrel, glaucomys volans, is a zoonotic reservoir of rickettsia prowazekii - causative agent of louse-borne (epidemic) typhus. the sporadic cases o f typhus that have occurred in the usa in association with flying squirrels provide evidence that flying squirrels can transmit r. prowazekii infection to humons. strains of r. prowazekii, isolated from flying squirrels multiply readily in human body lice, but flying squi ... | 1987 | 15462918 |
| localization of antigen in tissue cells; antigens of rickettsiae and mumps virus. | rickettsiae of epidemic typhus fever and rocky mountain spotted fever have been microscopically localized and identified in smears of exudates and tissue sections from infected cotton rats by means of homologous antibody labelled with fluorescein. epidemic typhus has also been identified in smears from single infected human body lice. mumps virus antigen has been microscopically localized in the parotid of the experimentally infected monkey by the same method. the antigenic material, probably ac ... | 1950 | 15395571 |

| [ivermectin]. | ivermectin is a semi-synthetic derivative of a macrocyclic lactone. it causes paralysis in many nematodes and arthropodes because of its effect on ion-channels in cell membranes. ivermectin was first used in veterinary medicine. in man, it was shown to be microfilaricid against onchocerca volvulus. most of the adverse reactions following treatment were mild, without the systemic and ocular side effects usually complicating diethylcarbamazine therapy. in endemic areas after repeated administratio ... | 2004 | 15318139 |
| use of human lice in forensic entomology. | hematophagus arthropod bloodmeals may be useful in identifying individual hosts. to examine the application of human lice as a forensic tool, that is, as evidence of physical contact between individuals, body lice from a laboratory colony and head lice, collected from the head of infested children, were studied. the dna profile of an individual was detectable in the pooled bloodmeals of two body lice, up to 20 h postfeeding. a mixed dna profile of two hosts was identifiable in the pooled bloodme ... | 2004 | 15311479 |
| insecticidal activity of plant essential oils against pediculus humanus capitis (anoplura: pediculidae). | the insecticidal activity of 54 plant essential oils against female pediculus humanus capitis de geer was examined using direct contact and fumigation methods, and compared with the lethal activity of delta-phenothrin and pyrethrum, two commonly used pediculicides. in a filter paper contact bioassay with female p. humanus capitis, the pediculicidal activity was more pronounced in eucalyptus, marjoram, pennyroyal, and rosemary oils than in delta-phenothrin and pyrethrum on the basis of lt50 value ... | 2004 | 15311463 |
| economic considerations associated with pediculus humanus capitis infestation. | an estimated 6 to 12 million head lice infestations occur in the united states annually, with children ages 3 to 12 most likely to be affected. there are significant direct costs associated with treatment and indirect costs due to lost time from school. anecdotal reports suggest that direct costs of treatment are in the hundreds of millions of dollars annually. indirect costs are also substantial but more difficult to quantify. examples of indirect costs include missed days from schools that use ... | 2004 | 15248004 |
| pediculosis capitis among schoolchildren in urban and rural areas of eastern poland. | the objective of this study was to compare the prevalence of head pediculosis in the rural and urban environments of lublin province (eastern poland) in 1996-2000 and to examine socioeconomic factors influencing distribution among schoolchildren. a total of 95,153 schoolchildren living in urban and rural areas were examined twice yearly by school nurses. the overall rate of head pediculosis differs significantly between rural (1.59%) and urban (0.48%) schools in eastern poland. children between ... | 2004 | 15233324 |
| use of topical nicotine for treatment of pediculus humanus capitis (anaplura: pediculidae). | head lice are caused by the host-specific, ectoparasitic insect pediculus humanus capitis de geer and remain a common human infestation. as a response to increasing resistance of head lice to present insecticidal agents, additional agents must be pursued. inasmuch as nicotine has been used for controlling poultry lice, an in vitro study assessing its possible usage for human head lice was performed. nicotine proved not to be an efficient insecticide, although it may facilitate removal of adult l ... | 2000 | 15218922 |
| infestation of people with lice in kathmandu and pokhara, nepal. | the prevalence of infestation with head lice and body lice, pediculus spp. (phthiraptera: pediculidae) and pubic (crab) lice pthirus pubis (l.) (phthiraptera: pthiridae), was recorded from 484 people in nepal. the prevalence of head lice varied from 16% in a sample of people aged 10-39 years of age, to 59% in street children. simultaneous infestations with head and body lice (double infestations) varied from 18% in slum children to 59% in street children. | 2004 | 15189249 |
| managing head lice in an era of increasing resistance to insecticides. | head lice are present in all age groups, however, the peak age for infestation is 7-8 years and the incidence varies throughout the year with higher incidence during the winter. different insecticides have been used over the past 60 years to manage this condition. there is now strong evidence of insecticide resistance established in many countries to such an extent that some of these chemicals have become obsolete. resistance to some pediculicides can vary from country to country and region to r ... | 2004 | 15186196 |
| semi-automated quantification of ivermectin in rat and human plasma using protein precipitation and filtration with liquid chromatography/tandem mass spectrometry. | ivermectin is a parasiticide commonly used in humans and livestock. it is currently under development for the treatment of pediculosis of humans (head lice) that does not respond to established treatments. a liquid chromatography/turbo ion spray tandem mass spectrometry (lc/tis-ms/ms) method for the determination of ivermectin in rat and human plasma has been developed that uses emamectin [4"-epi-(methylamino)-4"-deoxyavermectin] as the internal standard. sample preparation involved protein prec ... | 2004 | 15174180 |
| the sex ratio distortion in the human head louse is conserved over time. | at the turn of the 19th century the first observations of a female-biased sex ratio in broods and populations of the head louse, pediculus humanus capitis, had been reported. a study by buxton in 1940 on the sex ratio of lice on prisoners in ceylon is still today the subject of reanalyses. this sex ratio distortion had been detected in ten different countries. in the last sixty years no new data have been collected, especially on scalp infestations under economically and socially more developed ... | 2004 | 15140268 |
| relationship of treatment-resistant head lice to the safety and efficacy of pediculicides. | head lice infestation is a common and growing problem that primarily affects school-aged children. most cases of head lice are diagnosed and treated by nonphysicians. misdiagnosis may lead to treatment when no lice are present. treatment failure may lead to repeated use of and improperly applied pediculicides, potentially resulting in overexposure to pesticides. these treatment failures are primarily due to the emergence of treatment-resistant lice. in regions where resistant lice are common, pa ... | 2004 | 15132409 |
| ovicidal and adulticidal activity of eucalyptus globulus leaf oil terpenoids against pediculus humanus capitis (anoplura: pediculidae). | the toxic effects of eucalyptus globulus leaf oil-derived monoterpenoids [1,8-cineole, l-phellandrene, (-)-alpha-pinene, 2-beta-pinene, trans-pinocarveol, gamma-terpinene, and 1-alpha-terpineol] and the known eucalyptusleaf oil terpenoids (beta-eudesmol and geranyl acetate) on eggs and females of the human head louse, pediculus humanus capitis, were examined using direct contact and fumigation bioassays and compared with the lethal activity of delta-phenothrin and pyrethrum, two commonly used pe ... | 2004 | 15113148 |

| ectoparasites--the underestimated realm. | context: ectoparasitoses (infestations with parasites that live on or in the skin) can cause considerable morbidity. whereas pediculosis and scabies are ubiquitous, cutaneous larva migrans and tungiasis (sand-flea disease) occur mainly in hot climates. the prevalence of ectoparasitoses in the general population is usually low, but can be high in vulnerable groups. scientific knowledge on how to deal best with parasitic skin diseases in different settings is scanty, and evidence-based measures fo ... | 2004 | 15032237 |
| inhibition of acetylcholinesterase by tea tree oil. | pediculosis is a widespread condition reported in schoolchildren. treatment most commonly involves the physical removal of nits using fine-toothcombs and the chemical treatment of adult lice and eggs with topical preparations. the active constituents of these preparations frequently exert their effects through inhibition of acetylcholinesterase (ache, ec 3.1.1.7). increasing resistance to many preparations has led to the search for more effective treatments. tea tree oil, otherwise known as mela ... | 2004 | 15025863 |

| cloning and characterization of a trypsin-encoding cdna of the human body louse pediculus humanus. | from a cdna library of the whole insect, a trypsin gene of pediculus humanus has been cloned and sequenced. the 908 bp clone has an open reading frame of 759 bp, which encodes a pre-proenzyme with 253 amino acid residues. a sixteen-residue n-terminal signal peptide is followed by a twelve-residue activation peptide with putative cleavage sites at gly16 and tyr28. the deduced amino acid sequence has several features typical of trypsin proteases and an overall identity of 35-43% with the trypsins ... | 2004 | 14728662 |
| incidence and prevalence of head lice in a district health authority area. | there are very few recent studies of the incidence and prevalence of head lice in the uk. a population-based questionnaire survey was carried out in a district health authority area. two hundred and four of 235 primary schools (87%) agreed to participate. a total of 21,556 of 43,889 (49%) questionnaires were returned by parents. overall 438 children had head lice at the time of the survey, giving a prevalence of 2.03%; 8,059 had had lice at some time in the last year giving an annual incidence o ... | 2003 | 14708276 |
| pediculosis. | the 3 major lice that infest humans are pediculus humanus capitis (head louse), pthirus pubis (crab louse), and pediculus humanus humanus (body louse). patients with louse infestation present with scalp pruritus, excoriations, cervical lymphadenopathy, and conjunctivitis. a hypersensitivity rash, or pediculid, may mimic a viral exanthem. head lice infestation crosses all economic and social boundaries, whereas body lice infestation preferentially affects the homeless and displaced. body lice are ... | 2004 | 14699358 |
| body louse remains found in textiles excavated at masada, israel. | a leg of the body louse, pediculus humanus humanus l. (phthiraptera: pediculidae), was found in a storeroom at masada build during the reign of king herod the great. the unearthed culture material clearly indicates that the room was occupied by the rebels during the first jewish revolt against the romans (ad 66-73/4). the context of the textiles associated with the louse and their nature suggest a rebel origin. an exuvium of a leg of the third nymphal stage of body louse was found. the first thr ... | 2003 | 14680131 |
| molecular analysis of a para sodium channel gene from pyrethroid-resistant head lice, pediculus humanus capitis (anoplura: pediculidae). | the problem of pyrethroid-resistance in head lice, pediculus humanus capitis (de geer), is growing worldwide, and an insensitive sodium channel is suspected as the major mechanism of this resistance. we sequenced an open reading frame (orf) encoding for the para-orthologous sodium channel from an insecticide-susceptible strain of the body louse, pediculus humanus humanus (l.), based on conserved peptide sequences and a known partial gene sequence. phenothrin-susceptible and -resistant head louse ... | 2003 | 14680113 |
| prevalence and levels of permethrin resistance in pediculus humanus capitis de geer (anoplura: pediculidae) from buenos aires, argentina. | permethrin has been used extensively for control of pediculus humanus capitis de geer (anoplura: pediculidae) in argentina since 1990, resulting in the development of resistance to this and other pyrethroids. this resistance was first detected in some field populations in 1997. a survey for resistance in buenos aires in 2001 revealed significant resistance levels in lice on children at 24 of 26 (92.3%) schools. when compared with a previously unexposed reference population, resistance ratios (rr ... | 2003 | 14680109 |
| human lice and their control. | current research on human louse biology has focused on the long-standing debate about speciation of head and body lice but using new tools of dna and enzyme analysis. these studies have indicated that head and body lice from the same geographical zone may be more closely allied than insects inhabiting the same ecological niche in other regions. however, the majority of research over the past decade has involved clinical aspects including transmission, treatment, and the appearance and identifica ... | 2004 | 14651472 |
