    Closing the gap: avian lineage splits at a young, narrow seaway imply a protracted history of mixed population response.
    Mol Ecol 2017 Aug 14. Epub 2017 Aug 14.
    Ecology Group, Institute of Agriculture and Environment, Massey University, Palmerston North, 4442, New Zealand.
    The evolutionary significance of spatial habitat gaps has been well recognised since Alfred Russel Wallace compared the faunas of Bali and Lombok. Gaps between islands influence population structuring of some species, and flightless birds are expected to show strong partitioning even where habitat gaps are narrow. We examined the population structure of the most numerous living flightless land bird in New Zealand and the world, Weka (Gallirallus australis). Read More

At present, there is limited knowledge of how lumpfish respond upon anaesthesia, which anaesthetics and concentrations that are efficient and conditions for euthanasia. 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

    Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis).
    J Lipid Res 2017 Aug 10;58(8):1613-1623. Epub 2017 Jun 10.
    Molecular Biology, Sea Lice Research Centre, University of Bergen, N-5020 Bergen, Norway
    The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish. Salmon lice produce high numbers of offspring, necessitating sequestration of large amounts of lipids into growing oocytes as a major energy source for larvae, most probably mediated by lipoproteins. The microsomal triglyceride transfer protein (MTP) is essential for the assembly of lipoproteins. Read More

    Rapid growth causes abnormal vaterite formation in farmed fish otoliths.
    J Exp Biol 2017 Aug 8;220(Pt 16):2965-2969. Epub 2017 Jun 8.
    School of BioSciences, University of Melbourne, VIC 3010, Australia.
    Sagittal otoliths are essential components of the sensory organs that enable all teleost fish to hear and maintain balance, and are primarily composed of calcium carbonate. A deformity, where aragonite (the normal crystal form) is replaced with vaterite, was first noted over 50 years ago but its underlying cause is unresolved. We evaluated the prevalence of vateritic otoliths from two captive rearing studies which suggested that fast growth, due to environmental rather than genetic control, led to vaterite development.

    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

In the present study, a 63-year-old woman presented with a case of phthiriasis palpebrarum, which was initially misdiagnosed as anterior blepharitis. The patient had a 2-month history of repeated episodes of itching and burning sensations and moderate pain in both eyes that were not improved by antibiotic and corticosteroid eye drops. Read More

    Reduced growth in wild juvenile sockeye salmon Oncorhynchus nerka infected with sea lice.

    Daily growth rings were examined in the otoliths of wild juvenile sockeye salmon Oncorhynchus nerka to determine whether infection by ectoparasitic sea lice Caligus clemensi and Lepeophtheirus salmonis was associated with reduced host body growth, an important determinant of survival. Over 98% of the sea lice proved to be C. clemensi and the fish that were highly infected grew more slowly than uninfected individuals. Read More

    In recent years, the increase of head louse infestation in Iran (7.4%) and especially in West-Azerbaijan Province (248%) has raised the hypothesis of insecticide resistance development. There are different mechanisms of resistance to various groups of insecticides, and knockdown resistance (kdr) is a prominent mechanism of resistance to pyrethroids, an insecticide group which is used conventionally for pediculosis control.

    Resistance towards antiparasitic agents in the salmon louse (Lepeophtheirus salmonis) is a widespread problem along the Norwegian coast, reducing treatments efficacies and slowing down the envisioned expansion of Norwegian salmon production. The present study was conducted in order to assess the efficacies of two of the most widely used anti-parasitic substances-azamethiphos and deltamethrin-as well as assessing the benefit of having a resistant genotype compared to being fully sensitive when exposed to one of these substances. Atlantic salmon were exposed to a mix of salmon lice copepodids from a fully sensitive, a double resistant and a multi-resistant strain. Read More

    Ivermectin lipid-based nanocarriers as novel formulations against head lice.

    The use of pyrethroids to control the human head louse, Pediculus humanus capitis De Geer (Anoplura: Pediculidae), has suffered considerable loss of efficacy due to the evolution of resistance. Thus, the development of efficiently insecticide delivery systems is imperative for the control of head lice. We studied the insecticidal activity of ivermectin-loaded lipid nanocapsules (IVM-LNC) against permethrin-resistant head lice from Argentina. Read More
