    Centre for Veterinary Epidemiological Research, Department of Health Management, Atlantic Veterinary College, University of Prince Edward Island, Charlottetown, PE, C1A 4P3, Canada.
    Sea lice are marine parasites affecting salmon farms, and are considered one of the most costly pests of the salmon aquaculture industry. Infestations of sea lice on farms significantly increase opportunities for the parasite to spread in the surrounding ecosystem, making control of this pest a challenging issue for salmon producers. The complexity of controlling sea lice on salmon farms requires frequent monitoring of the abundance of different sea lice stages over time. Read More

    Insights About Head Lice Transmission From Field Data and Mathematical Modeling.
    J Med Entomol 2018 Feb 22. Epub 2018 Feb 22.
    Grupo de Física Estadística e interdisciplinaria, Centro Atómico Bariloche & CONICET, Bariloche, Argentina.
    Head lice infest millions of school-age children every year, both in developed and developing countries. However, little is known about the number of lice transferred among children during school activities, because direct methods to study this are almost impossible to implement. This issue has been addressed following an indirect method, which consist in collecting data of real infestation from several children groups and using a mathematical model of lice colonies to infer how the infestation observed might have evolved.

    Les infestations par les poux de tête : une mise à jour clinique.
    Paediatr Child Health 2018 Feb 15;23(1):e25-e32. Epub 2018 Feb 15.
    Société canadienne de pédiatrie, comité de la pédiatrie communautaire, Ottawa (Ontario).
    Les infestations par les poux de tête () ne constituent ni un risque sanitaire primaire ni un vecteur de maladie, mais représentent plutôt un problème de société au coût impor- tant. Pour diagnostiquer une infestation, il faut déceler un pou vivant. Même si les pyréthines et la perméthrine demeurent les traitements de première intention au Canada, la solution de myristate d'isopropyle et de ST-cyclométhicone et la diméticone peuvent être envisagées en deuxième intention après un échec thérapeutique démontré.

    Head lice infestations: A clinical update.
    Paediatr Child Health 2018 Feb 15;23(1):e18-e24. Epub 2018 Feb 15.
    Canadian Paediatric Society, Community Paediatrics Committee, Ottawa, Ontario.
    Head lice () infestations are not a primary health hazard or a vector for disease, but they are a societal problem with substantial costs. Diagnosis of head lice infestation requires the detection of a living louse. Although pyrethrins and permethrin remain first-line treatments in Canada, isopropyl myristate/ST-cyclomethicone solution and dimeticone can be considered as second-line therapies when there is evidence of treatment failure.

    Detection of bacterial pathogens including potential new species in human head lice from Mali.
    PLoS One 2017 20;12(9):e0184621. Epub 2017 Sep 20.
    Aix Marseille Univ, CNRS, IRD, INSERM, AP-HM, URMITE, IHU - Méditerranée Infection, Marseille, France.
    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. Read More

    Behavioural responses of infective-stage copepodids of the salmon louse (Lepeophtheirus salmonis, Copepoda:Caligidae) to host-related sensory cues.
    J Fish Dis 2017 Sep 17. Epub 2017 Sep 17.
    Institute of Marine Research, Austevoll Research Station, Storebø, Norway.
    The salmon louse (Lepeophtheirus salmonis [Krøyer]) is an ectoparasitic copepod that causes disease in farmed Atlantic salmon (Salmo salar) and may play a role in the decline of some wild salmonid populations. Controlling lice infestations is a major cost for the salmon industry; this has stimulated the pursuit of alternative approaches to controlling them. One such approach involves determining, and then disrupting, the sensory cues used by the parasite to find its host. Read More

    [Diseases affecting the scalp].
    Cas Lek Cesk 2017 ;156(3):137-140
    The skin of the scalp differs from the skin on the other areas of the body because of a higher density of hair follicles and higher sebum production. These, together with the presence of hair, provide a suitable environment for superficial infections, infestations and inflammatory diseases. The good condition of the scalp has a significant impact on the patient's mental well-being and social interaction. Read More

    Are scabies and impetigo "normalised"? A cross-sectional comparative study of hospitalised children in northern Australia assessing clinical recognition and treatment of skin infections.
    PLoS Negl Trop Dis 2017 Jul 3;11(7):e0005726. Epub 2017 Jul 3.
    Department of Infectious Diseases, Princess Margaret Hospital for Children, Perth, Western Australia.
    Background: Complications of scabies and impetigo such as glomerulonephritis and invasive bacterial infection in Australian Aboriginal children remain significant problems and the overall global burden of disease attributable to these skin infections remains high despite the availability of effective treatment. We hypothesised that one factor contributing to this high burden is that skin infection is under-recognised and hence under-treated, in settings where prevalence is high.

    Methods: We conducted a prospective, cross-sectional study to assess the burden of scabies, impetigo, tinea and pediculosis in children admitted to two regional Australian hospitals from October 2015 to January 2016. Read More

    Microbes and masculinity: Does exposure to pathogenic cues alter women's preferences for male facial masculinity and beardedness?
    PLoS One 2017 8;12(6):e0178206. Epub 2017 Jun 8.
    School of Psychology, University of Queensland, Brisbane, Queensland, Australia.
    Women's preferences for men's androgen dependent secondary sexual traits are proposed to be phenotypically plastic in response to exposure to pathogens and pathogen disgust. While previous studies report that masculinity in facial shape is more attractive to women who have recently been exposed to pathogenic cues and who are high in self-reported pathogen disgust, facial hair may reduce male attractiveness under conditions of high pathogens as beards are a possible breeding ground for disease carrying ectoparasites. In the present study, we test whether women's preferences for beardedness and facial masculinity vary due to exposure to different pathogenic cues. Read More
