    Morphology of immature stages of blow fly, Lucilia sinensis Aubertin (Diptera: Calliphoridae), a potential species of forensic importance.
    Acta Trop 2017 Sep 19. Epub 2017 Sep 19.
    Department of Parasitology, Faculty of Medicine, Chiang Mai University, Chiang Mai 50200, Thailand. Electronic address:
    Lucilia sinensis Aubertin (Diptera: Calliphoridae) is a blow fly species of potential forensic importance since adults are attracted to, and colonize, decomposing vertebrate remains. Blow fly larvae associated with human corpses can be useful evidence in forensic investigations; however, their use is dependent in most cases on proper species identification and availability of developmental data. For identification, morphological information on each life stage is traditionally used. Read More

    Presence of a predator image in potential breeding sites and oviposition responses of a dengue vector.
    Acta Trop 2017 Aug 30. Epub 2017 Aug 30.
    Institute of Biodiversity and Environmental Conservation (IBEC), Universiti Malaysia Sarawak, Kuching, Kota Samarahan, Malaysia.
    In dengue vector control, attempts to minimize or replace the use of pesticides have mostly involved use of predators, but success has been severely impeded by difficulties associated with financial and environmental costs, predator mass production, and persistence in target habitats. Visual deterrents have been used successfully to control animal pests, in some cases in an effort to replace pesticide use. Despite evidence that visual signals are crucial in site choice for egg deposition by dengue vectors, and that female mosquitoes respond to artificial predation, the role of predator intimidation as it affects the oviposition behavior of dengue vectors remains largely unexplored.

    The occurrence of Aedes aegypti, Culex quinquefasciatus, and mosquitoes of the genus Anopheles potentiate the spread of several diseases, such as dengue, Zika, chikungunya, urban yellow fever, filariasis, and malaria, a situation currently existing in Brazil and in Latin America. Control of the disease vectors is the most effective tool for containing the transmission of the pathogens causing these diseases, and the bacterium Bacillus thuringiensis var. israelensis has been widely used and has shown efficacy over many years.

    Leptospirosis: Molecular trial path and immunopathogenesis correlated with dengue, malaria and mimetic hemorrhagic infections.
    Acta Trop 2017 Aug 16;176:206-223. Epub 2017 Aug 16.
    Department of Medical Microbiology and Parasitology, Universiti Putra Malaysia, 43400 UPM Serdang Selangor, Malaysia; Genetics and Regenerative Medicine Research Centre, Universiti Putra Malaysia, 43400 UPM Serdang, Selangor, Malaysia. Electronic address:
    Immuno-pathogenesis of leptospirosis can be recounted well by following its trail path from entry to exit, while inducing disastrous damages in various tissues of the host. Dysregulated, inappropriate and excessive immune responses are unanimously blamed in fatal leptospirosis. The inherent abilities of the pathogen and inabilities of the host were debated targeting the severity of the disease. Read More

    Cross-sectional analysis of the association between bedtime and malaria exposure in the Ouest and Sud-Est Departments of Haiti.

    Introduction: The governments of Haiti and the Dominican Republic have a binational agreement to work towards malaria elimination for the island of Hispaniola by the year 2020. Understanding malaria-related knowledge and behaviors can help inform elimination efforts. This study examined the association between social-behavioral factors, like bedtime and bed net ownership, with malaria seroconversion status among people in the Ouest and Sud-Est departments of Haiti.

    Wild populations of Triatoma infestans: Compilation of positive sites and comparison of their ecological niche with domestic population niche.
    Acta Trop 2017 Aug 15;176:228-235. Epub 2017 Aug 15.
    Instituto Altos Estudios Espaciales Mario Gulich, Universidad Nacional Córdoba-CONAE, Ruta C45 Km 8, Falda del Cañete, 5187 Córdoba, Argentina.
    Background: For several years, the wild populations of Triatoma infestans, main vector of Trypanosoma cruzi causing Chagas disease, have been considered or suspected of being a source of reinfestation of villages. The number of sites reported for the presence of wild T. infestans, often close to human habitats, has greatly increased, but these data are scattered in several publications, and others obtained by our team in Bolivia have not been published yet.

    Neglected tropical diseases (NTDs) affect millions of people in different geographic regions, especially the poorest and most vulnerable. Currently NTDs are prevalent in 149 countries, seventeen of these neglected tropical parasitic diseases are classified as endemic. One of the most important of these diseases is schistosomiasis, also known as bilharzia, a disease caused by the genus Schistosoma. Read More

    Antibiotic susceptibilities and prevalence of Methicillin resistant Staphylococcus aureus (MRSA) isolated from bovine milk in Pakistan.
    Acta Trop 2017 Aug 7;176:168-172. Epub 2017 Aug 7.
    Department of Clinical Medicine and Surgery, Faculty of Veterinary Science, University of Veterinary and Animal Sciences, Lahore-54000, Pakistan.
    The study was designed to investigate bovine milk for prevalence of an emerging zoonotic pathogen Methicillin resistant Staphylococcus aureus (MRSA), and in-vitro therapeutic response of various antibiotics against MRSA. Nine hundred (900) milk samples were collected (half from cattle and half from buffalo) from private and public farms located in various tehsils of district Faisalabad, using the convenient sampling method. Milk samples were put to biochemical identification of Staphylococcus aureus and later oxacilline disk sensitivity testing for confirmation of MRSA. Read More

    Elevated seroprevalence of Toxoplasma gondii in AIDS/HIV patients: A meta-analysis.

    Clinical toxoplasmosis in AIDS/HIV patients is a great public health concern around the world. Untreated Toxoplasma gondii (T. gondii)-infections are often fatal in AIDS/HIV patients. Read More

    New Haemoproteus parasite of parrots, with remarks on the virulence of haemoproteids in naive avian hosts.
    Acta Trop 2017 Aug 4;176:256-262. Epub 2017 Aug 4.
    Institute of Animal Pathology, Vetsuisse Faculty, University of Bern, Länggassstrasse 122, 3012 Bern, Switzerland.
    Haemoproteus infections can cause fatal disease in parrots (Psittaciformes), one of the most endangered groups of birds. The great diversity of parrots in tropical and subtropical ecosystems has been markedly understudied in terms of their parasite diversity. Only two psittacine Haemoproteus species have been described. Read More
