    Host density increases parasite recruitment but decreases host risk in a snail-trematode system.
    Ecology 2017 May 18. Epub 2017 May 18.
    U.S. Geological Survey, Western Ecological Research Center, c/o Marine Science Institute University of California Santa Barbara, Santa Barbara, CA, 93106, USA.
    Most species aggregate in local patches. High host density in patches increases contact rate between hosts and parasites, increasing parasite transmission success. At the same time, for environmentally-transmitted parasites, high host density can decrease infection risk to individual hosts, because infective stages are divided among all hosts in a patch, leading to safety in numbers.

    Infection, specificity and host manipulation of Australapatemon sp. (Trematoda, Strigeidae) in two sympatric species of leeches (Hirudinea).
    Parasitology 2017 May 15:1-10. Epub 2017 May 15.
    Department of Biological and Environmental Science,University of Jyvaskyla,PO Box 35, 40014 Jyvaskyla,Finland.
    Factors that drive parasite specificity and differences in infection dynamics among alternative host species are important for ecology and evolution of host-parasite interactions, but still often poorly known in natural systems. Here, we investigated spatiotemporal dynamics of infection, host susceptibility and parasite-induced changes in host phenotype in a rarely explored host-parasite system, the Australapatemon sp. trematode infecting two sympatric species of freshwater leeches, Erpobdella octoculata and Helobdella stagnalis.

    Neglected tropical diseases (NTDs) are a group of diseases that, besides prevailing in poverty conditions, contribute to the maintenance of social inequality, being a strong barrier to a country development. Schistosomiasis, a NTD, is a tropical and subtropical disease caused by the trematode Schistosoma mansoni (Africa, Middle East, Caribbean, Brazil, Venezuela, Suriname), japonicum (China, Indonesia, the Philippines), mekongi (several districts of Cambodia and the Lao People's Democratic Republic), intercalatum and guianensis (areas of tropical rainforests in Central Africa) and hematobium (Middle East Africa, Corsica, France) whose adult forms inhabit the mesenteric vessels of the host, while the intermediate forms are found in the aquatic gastropod snails of the genus Biomphalaria. Currently, praziquantel (PZQ) is the first line drug chosen for the treatment of schistosomiasis according to the World Health Organization (WHO) Model List of Essential Medicines, 2015. Read More

    Network Analysis of the Systemic Response to Fasciola hepatica Infection in Sheep Reveals Changes in Fibrosis, Apoptosis, Toll-Like Receptors 3/4, and B Cell Function.
    Front Immunol 2017 25;8:485. Epub 2017 Apr 25.
    UCD School of Veterinary Medicine, University College Dublin, Dublin, Ireland.
    The Trematode Fasciola hepatica is an important cause of disease in livestock and in man. Modulation of immunity is a critical strategy used by this parasite to facilitate its long-term survival in the host. Understanding the underlying mechanisms at a system level is important for the development of novel control strategies, such as vaccination, as well as for increasing general understanding of helminth-mediated immunoregulation and its consequences.

    Th9 Cells and Parasitic Inflammation: Use of Nippostrongylus and Schistosoma Models.
    Methods Mol Biol 2017 ;1585:223-245
    Departamento de Biología Celular y del Desarrollo, Instituto de Fisiología Celular, Universidad Nacional Autónoma de México, Ciudad Universitaria, Coyoacán, 04510, Mexico City, Mexico.
    Th9 cells are a new subpopulation of CD4+ T helper cells, characterized by the expression of IL-9 that have been involved in type 2 immune responses, antitumor responses and autoimmune diseases. Here, we describe two different parasitic models frequently maintained in the laboratory where Th9 cells or IL-9 (the cytokine produced by Th9 cells) has been shown to play critical roles in pathogen clearance and immune response activation: the nematode Nippostrongylus brasiliensis and the trematode Schistosoma mansoni.

    Behavioural modification of personality traits: testing the effect of a trematode on nymphs of the red damselfly Xanthocnemis zealandica.
    Parasitol Res 2017 Jun 4;116(6):1773-1779. Epub 2017 May 4.
    Department of Zoology, University of Otago, PO Box 56, Dunedin, 9054, New Zealand.
    Research on animal personality is increasingly demonstrating that individuals in a population are characterised by distinct sets of behavioural traits that show consistency over time and across different situations. Parasites are known to alter the behaviour of their hosts, although their role in shaping host personality remains little studied. Here, we test the effect of trematode infection on two traits of their host's personality, activity and boldness, in nymphs of the red damselfly Xanthocnemis zealandica. Read More

    Genomic evidence for population-specific responses to co-evolving parasites in a New Zealand freshwater snail.
    Mol Ecol 2017 Apr 21. Epub 2017 Apr 21.
    Department of Biology, University of Iowa, Iowa City, IA, USA.
    Reciprocal co-evolving interactions between hosts and parasites are a primary source of strong selection that can promote rapid and often population- or genotype-specific evolutionary change. These host-parasite interactions are also a major source of disease. Despite their importance, very little is known about the genomic basis of co-evolving host-parasite interactions in natural populations, especially in animals. Read More

    The immunoregulatory effects of co-infection with Fasciola hepatica: From bovine tuberculosis to Johne's disease.
    Vet J 2017 Apr 2;222:9-16. Epub 2017 Mar 2.
    UCD School of Veterinary Medicine, University College Dublin, Belfield, Dublin 4, Ireland.
    Fasciola hepatica (liver fluke) is a parasite prevalent in much of the world that causes the economically-important disease of fasciolosis in livestock. The threat that this disease poses extends beyond its direct effects due to the parasite's immunomodulatory effects. Research at this laboratory is focusing on whether this immunoregulation can, in animals infected with liver fluke, exert a bystander effect on concurrent infections in the host. Read More

    Mathematical algorithm for the automatic recognition of intestinal parasites.
    PLoS One 2017 14;12(4):e0175646. Epub 2017 Apr 14.
    Unidad de Bioinformática, Laboratorios de Investigación y Desarrollo, Facultad de Ciencias y Filosofía, Universidad Peruana Cayetano Heredia, Lima, Perú.
    Parasitic infections are generally diagnosed by professionals trained to recognize the morphological characteristics of the eggs in microscopic images of fecal smears. However, this laboratory diagnosis requires medical specialists which are lacking in many of the areas where these infections are most prevalent. In response to this public health issue, we developed a software based on pattern recognition analysis from microscopi digital images of fecal smears, capable of automatically recognizing and diagnosing common human intestinal parasites.

    South Korea presently uses an arbitrary sampling method to monitor the prevalence of Clonorchis sinensis infection in the endemic areas of the country. However, the present method is not standardized and focuses primarily on individuals who reside nearest to the mainstream river. We propose a new sampling method that combines cluster sampling with proportionate quota sampling to ensure that the entire endemic area is accurately represented. Read More

    Controlling schistosomiasis with praziquantel: How much longer without a viable alternative?
    Infect Dis Poverty 2017 Mar 28;6(1):74. Epub 2017 Mar 28.
    Swiss Tropical and Public Health Institute, P.O. Box, CH-4002, Basel, Switzerland.
    The current approach of morbidity control of schistosomiasis, a helminth disease of poverty with considerable public health and socioeconomic impact, is based on preventive chemotherapy with praziquantel. There is a pressing need for new drugs against this disease whose control entirely depends on this single drug that has been widely used over the past 40 years. We argue that a broader anthelminthic approach supplementing praziquantel with new antischistosomals targeting different parasite development stages would not only increase efficacy but also reduce the risk for drug resistance.

    * Virginia Polytechnic Institute and State University Graduate student Department of Biological Sciences Virginia Polytechnic Institute and State University.
    Understanding temporal variation of host-pathogen dynamics can be important for predicting disease risks and anticipating how disease systems may change in response to natural or human disturbances. Seasonal changes in weather, especially those associated with changes in temperature or precipitation, are often a key component of temporal changes in infection risk and can have important impacts on disease systems. However, these patterns can be difficult to track due to interannual variation and the need for longer-term, multi-year surveillance efforts. Read More

    The role of estradiol metabolism in urogenital schistosomiasis-induced bladder cancer.
    Tumour Biol 2017 Mar;39(3):1010428317692247
    2 Center for the Study of Animal Science, ICETA, University of Porto, Porto, Portugal.
    Urogenital schistosomiasis is a neglected tropical disease that can lead to bladder cancer. How urogenital schistosomiasis induces carcinogenesis remains unclear, although there is evidence that the human blood fluke Schistosoma haematobium, the infectious agent of urogenital schistosomiasis, releases estradiol-like metabolites. These kind of compounds have been implicated in other cancers. Read More
