21. First molecular detection of Mycoplasma suis in the pig louse Haematopinus suis (Phthiraptera: Anoplura) from Argentina. (Abstract)

First molecular detection of Mycoplasma suis in the pig louse Haematopinus suis (Phthiraptera: Anoplura) from Argentina. Porcine haemoplasmosis caused by Mycoplasma suis affects the global pig industry with significant economic losses. The main transmission route of M. suis is through the blood and some haematophagous arthropods, like flies and mosquitoes, could be the vectors to this pathogen. However, the presence of M. suis in pig haematophagous ectoparasites in natural conditions has (...) not yet been studied. The most frequent ectoparasite in pigs is the blood-sucking louse Haematopinus suis, an obligate and permanent parasite. Therefore, this work aims to study the occurrence of M. suis in H. suis samples from both domestic and wild pig populations from Argentina; using the 16S rRNA gene. A total of 98 sucking lice, collected from domestic and wild pigs from Buenos Aires Province in central Argentina, were examined. We found M. suis DNA in 15 H. suis samples (15.30%). Positive lice

22. Ovicidal Efficacy of Abametapir Against Eggs of Human Head and Body Lice (Anoplura: Pediculidae) Full Text available with Trip Pro

Ovicidal Efficacy of Abametapir Against Eggs of Human Head and Body Lice (Anoplura: Pediculidae) Studies were undertaken to determine the ovicidal efficacy of 5,5'-dimethyl-2,2'-bipyridyl (abametapir) against eggs of both human head and body lice. Head lice eggs of different ages (0-2, 3-5, and 6-8-d-old eggs) were exposed to varying concentrations of abametapir in isopropanol and concentration-dependent response relationships established based on egg hatch. One hundred percent of all (...) abametapir-treated eggs failed to hatch at the 0.74 and 0.55% concentrations, whereas 100% of 6-8-d-old head louse eggs failed to hatch only at the 0.74% concentration. The LC50 value for abametapir varied, depending on the age of the head lice eggs, from ∼0.10% recorded for 0-2-d-old eggs and increasing to ∼0.15% for 6-8-d-old eggs. Abametapir was also evaluated once formulated into a lotion referred to as Xeglyze (0.74% abametapir) and serial dilutions made. Ovicidal efficacies were determined against

Efficacy and Safety of a Water-Based Head Lice Lotion: A Randomized, Controlled, Investigator-Blinded, Comparative, Bicentric Study. Silicones (e.g., dimethicone) are effective and safe alternatives to insecticides for the treatment of head lice. However, silicones are lipophilic substances and do not only leave the hair greasy but they are also difficult to wash out. We have evaluated the efficacy and safety of a potential solution to this problem: an aqueous dispersion of a novel silylated (...) polyol that has the same mode of action as dimethicone (suffocation) without its negative impact on hair characteristics.This was a randomized, controlled, investigator-blinded, bicentric study that was conducted at two locations in the state of Florida (USA) to compare the test product (medical device) to a pyrethrum-based pediculicide that is a first-line, prescription-free treatment against head lice in the USA. The subjects (n = 70) were randomly divided into two groups of 35 persons (test

25. Head lice infestations in rural Honduras: the need for an integrated approach to control neglected tropical diseases. (Abstract)

Head lice infestations in rural Honduras: the need for an integrated approach to control neglected tropical diseases. Pediculosis capitis is a neglected tropical disease (NTD) that receives little attention in countries where it continues to be endemic. This study aimed to understand the impact of Pediculus humanus capitis infestations in the lives of Honduran children living in extreme poverty.A qualitative study on head lice infestation was conducted in June 2016 in a rural community (...) in Honduras. Parents were invited to bring their children for head lice inspection using a dry-combing technique with a stainless steel-toothed comb with suction power. A semistructured questionnaire was administered to participants. Questions were broadly grouped into knowledge about transmission, control practices, barriers to treatment, and the overall impact of these infestations in children's wellbeing. Responses were coded, categorized, and organized through a theme-based approach.In total, 52

27. Detection of bacterial pathogens in clade E head lice collected from Niger’s refugees in Algeria Full Text available with Trip Pro

Detection of bacterial pathogens in clade E head lice collected from Niger’s refugees in Algeria Head lice, Pediculus humanus capitis, are obligate blood-sucking parasites. Phylogenetically, they occur in five divergent mitochondrial clades (A, D, B, C and E), each having a particular geographical distribution. Recent studies have revealed that head lice, as is the case of body lice, can act as a vector for louse-borne diseases. Here, we aimed to study the genetic diversity of head lice (...) collected from Niger's refugees (migrant population) arriving in Algeria, northern Africa, and to look for louse-borne pathogens. Comparative head lice samples collected from indigenous population of schoolchildren (non-immigrant) were also analyzed to frame the study.In this study, 37 head lice samples were collected from 31 Nigerien refugees, as well as 45 head lice from 27 schoolchildren. The collection was established in three localities of eastern Algiers, north Algeria. Quantitative real-time PCR

28. Do drowning and anoxia kill head lice? Full Text available with Trip Pro

Do drowning and anoxia kill head lice? Chemical, physical, and mechanical methods are used to control human lice. Attempts have been made to eradicate head lice Pediculus humanus capitis by hot air, soaking in various fluids or asphyxiation using occlusive treatments. In this study, we assessed the maximum time that head lice can survive anoxia (oxygen deprivation) and their ability to survive prolonged water immersion. We also observed the ingress of fluids across louse tracheae and spiracle (...) characteristics contrasting with those described in the literature. We showed that 100% of lice can withstand 8 h of anoxia and 12.2% survived 14 h of anoxia; survival was 48.9% in the untreated control group at 14 h. However, all lice had died following 16 h of anoxia. In contrast, the survival rate of water-immersed lice was significantly higher when compared with non-immersed lice after 6 h (100% vs. 76.6%, p = 0.0037), and 24 h (50.9% vs. 15.9%, p = 0.0003).

30. Detection of bacterial pathogens including potential new species in human head lice from Mali. Full Text available with Trip Pro

Detection of bacterial pathogens including potential new species in human head lice from Mali. In poor African countries, where no medical and biological facilities are available, the identification of potential emerging pathogens of concern at an early stage is challenging. Head lice, Pediculus humanus capitis, have a short life, feed only on human blood and do not transmit pathogens to their progeny. They are, therefore, a perfect tool for the xenodiagnosis of current or recent human (...) infection. This study assessed the occurrence of bacterial pathogens from head lice collected in two rural villages from Mali, where a high frequency of head lice infestation had previously been reported, using molecular methods. Results show that all 600 head lice, collected from 117 individuals, belonged to clade E, specific to West Africa. Bartonella quintana, the causative agent of trench fever, was identified in three of the 600 (0.5%) head lice studied. Our study also shows, for the first time

34. New records of chewing lice (Phthiraptera: Amblycera, Ischnocera) from Egyptian pigeons and doves (Columbiformes), with description of one new species. (Abstract)

New records of chewing lice (Phthiraptera: Amblycera, Ischnocera) from Egyptian pigeons and doves (Columbiformes), with description of one new species. Little information is available about the chewing lice of wild birds of Egypt, including common groups such as pigeons and doves (Columbiformes). Through this work, parasitic chewing lice of common columbiformes of Egypt were revised including new data. Three species of pigeons and doves (Streptopelia decaocto Frivaldszky 1838, Spilopelia (...) senegalensis Linnaeus 1766 and Columba livia Gmelin 1789) were examined for chewing lice at three different localities. A total of 124 specimens of lice were collected. Nine species were identified from these samples; one species (Columbicola joudiae n. sp.) was considered a new species to science, six species were recorded from Egypt for the first time, and two species have been identified in Egypt before. Taxonomic and ecological remarks for all identified chewing lice samples are provided along

Electron Microscopic Alterations in Pediculus humanus capitis Exposed to Some Pediculicidal Plant Extracts Head lice, Pediculus humanus capitis, infestation is an important public health problem in Egypt. Inadequate application of topical pediculicides and the increasing resistance to the commonly used pediculicides made the urgent need for the development of new agents able to induce irreversible changes in the exposed lice leading to their mortality. The aim of the present work is to evaluate (...) juice. The mortalities were decreased to 96.7% after exposure to tea tree oil. Very low percentage of mortality (23.3%) was recorded after 1 hr of exposure to extra virgin olive oil. On the other hand, the reference pediculicide (licid) revealed only mortality rate of 93.3%. On the contrary, no mortalities were recorded in the control group exposed to distilled water. By SEM examination, control lice preserved outer smooth architecture, eyes, antenna, respiratory spiracles, sensory hairs, and legs

39. The unusual reproductive system of head and body lice (Pediculus humanus) Full Text available with Trip Pro

The unusual reproductive system of head and body lice (Pediculus humanus) Insect reproduction is extremely variable, but the implications of alternative genetic systems are often overlooked in studies on the evolution of insecticide resistance. Both ecotypes of Pediculus humanus (Phthiraptera: Pediculidae), the human head and body lice, are human ectoparasites, the control of which is challenged by the recent spread of resistance alleles. The present study conclusively establishes for the first (...) time that both head and body lice reproduce through paternal genome elimination (PGE), an unusual genetic system in which males transmit only their maternally derived chromosomes. Here, we investigate inheritance patterns of parental genomes using a genotyping approach across families of both ecotypes and show that heterozygous males exclusively or preferentially pass on one allele only, whereas females transmit both in a Mendelian fashion. We do however observe occasional transmission of paternal
