    Using state-space models to predict the abundance of juvenile and adult sea lice on Atlantic salmon.
    Epidemics 2018 Apr 11. Epub 2018 Apr 11.
    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.

    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 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.

    An overview of cleaner fish use in Ireland.
    J Fish Dis 2017 Nov 21. Epub 2017 Nov 21.
    Carna Research Station, Ryan Institute, National University of Ireland, Galway, Carna, Co. Galway, Ireland.
    Sea lice infestations represent one of the most significant challenges facing the salmon farming industry, giving rise to lost production, additional costs of treatment and potential negative interactions with wild stocks. At present, cleaner fish, which actively remove lice from salmon, are an effective, biological, long-term option which has been adopted by many countries. In Ireland, several key studies were conducted in the 1990s on the use of wild-caught wrasse (corkwing, goldsinny and rock cook) as cleaner fish in experimental and commercial scale trials. Read More

    Departamento de Zoología de Invertebrados, Facultad de Ciencias Biológicas, Universidad Autónoma de Nuevo León, Nuevo León, México.
    Introduction: Pediculosis capitis is a recurring problem affecting 6 to 12 millions of children annually; there are no epidemiological data on this subject in the state of Nuevo León, and there are few in México. Therefore, new contributions are needed to design control strategies based on factors that may predispose to head lice infestation.

    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

    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.

    Microbes and masculinity: Does exposure to pathogenic cues alter women's preferences for male facial masculinity and beardedness?

    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

This condition is characterised by the formation of bacterial nodules. Clinically, it can be confused with white piedra or pediculosis. Read More
