    Dynamics of spatiotemporal distribution of schistosomiasis in Hubei Province, China.
    Acta Trop 2018 Jan 10. Epub 2018 Jan 10.
    Hubei Center for Disease Control and Prevention, Wuhan, China. Electronic address:
    Schistosomiasis caused by parasitic flatworms of blood flukes, remains a major public health concern in China. The significant progress in controlling schistosomiasis in China over the past decades has resulted in the remarkable reduction in the prevalence and intensity of Schistosoma japonicum infection to an extremely low level. Therefore, the elimination of schistosomiasis has been promoted by the Chinese national government. Read More

    Laboratório de Hantaviroses e Rickettsioses, Fundação Oswaldo Cruz, Instituto Oswaldo Cruz, Rio de Janeiro, CEP 21040-360 RJ, Brazil. Electronic address:
    Mammarenavirus species are associated with a specific rodent host species, although an increasing number of virus has been associated to more than one host, suggesting that co-evolution is less robust than initially thought. There are few eco-epidemiological studies of South America mammarenaviruses in non-endemic areas of Arenavirus Hemorrhagic Fever, affecting specially our current knowledge about animal reservoirs and virus range and host-virus relations. In Brazil, seven arenavirus species were described in seven different rodent species. Read More

Lateralization contributes to biological fitness in many animals, conferring important functional advantages, therefore studying its role in tick perception would critically improve our knowledge about their host-seeking behavior. In this research, we evaluated if Ixodes ricinus (L. Read More

    Paleoparasitological studies have demonstrated that changes in environment or culture are reflected in the patterns of parasitic infection diseases in populations worldwide. The advent of agriculture and animal domestication, with its accompanying reduction in human mobility and expanding population involves changes in or emergence of, parasites, the so-called first epidemiological transition. Cultural processes related to territory occupation contribute to both loss and acquisition of parasites. Read More

    Potential risk of a liver fluke Opisthorchis viverrini infection brought by immigrants from prevalent areas: A case study in the lower Northern Thailand.
    Acta Trop 2018 Feb 6;178:213-218. Epub 2017 Dec 6.
    The Office of Disease Prevention and Control 9, Phitsanulok, 65000, Thailand. Electronic address:
    Considering the long lifespan of the liver fluke Opisthorchis viverrini, human mobility from prevalent regions to other neighboring areas has the possibility to disperse carriers and complicate the opisthorchiasis problem. To evaluate this, mass screening of the fluke infection was conducted in nine communities of lower Northern Thailand, combined with a questionnaire survey to distinguish the participant's origin. The liver fluke infection was found in 70 individuals (7. Read More

    Sero-prevalence of Bovine Brucellosis and associated risk factors in mbeya region, Southern highlands of Tanzania.

    School of Veterinary Medicine, University of Zambia, P.O. Box 3239, Lusaka, Zambia.
    A cross-sectional study was conducted to establish the seroprevalence of brucellosis and associated risk factors in indigenous and exotic breeds of cattle from 178 farms in Mbeya region. A total of 1211 cattle (929exotic cattle from 108 commercial farms and 282 indigenous cattle from 70 traditional farms) were tested for Brucella antibodies using the Rose Bengal Plate Test (RBPT) and competitive Enzyme Linked Immunosorbent Assay (c-ELISA) as screening and confirmatory tests, respectively. The overall animal-level seroprevalence was 9. Read More

    Mapping the spatial distribution of Aedes aegypti and Aedes albopictus.

    Mosquito-borne infectious diseases, such as Rift Valley fever, Dengue, Chikungunya and Zika, have caused mass human death with the transnational expansion fueled by economic globalization. Simulating the distribution of the disease vectors is of great importance in formulating public health planning and disease control strategies. In the present study, we simulated the global distribution of Aedes aegypti and Aedes albopictus at a 5×5km spatial resolution with high-dimensional multidisciplinary datasets and machine learning methods Three relatively popular and robust machine learning models, including support vector machine (SVM), gradient boosting machine (GBM) and random forest (RF), were used.

    This study reports the molluscicidal activity of usnic acid isolated from Cladonia substellata Vanio (lichen) on embryos at various stages of development and in adult mollusks of Biomphalaria glabrata. The toxicity of usnic acid was also evaluated through Artemia salina larvae mortality. Usnic acid was extracted with diethyl ether, isolated, purified, and its structure confirmed by analyzing the spectra of proton nuclear magnetic resonance. Read More

    Identification of an area predominantly endemic for childhood and adolescent visceral leishmaniasis in central Sudan.
    Acta Trop 2018 Feb 26;178:142-147. Epub 2017 Nov 26.
    Laboratory of Biomedical Research, Ahfad University for Women, P.O. Box 167, Omdurman, Sudan. Electronic address:
    Although widely spread throughout Sudan, visceral leishmaniasis (VL) is predominantly endemic in the Gedaref, southern Blue-Nile, and Umrimta areas located in the eastern, southern, and central regions, respectively. Regardless of form (endemic or epidemic), VL occurrence follows similar patterns as all ages and both sexes are affected. From January 2005 to May 2016, we received a total of 563 patients with high suspicion for VL from various endemic areas; 159 were children and adolescents (0. Read More

    A retrospective study of human cystic echinococcosis in Basrah province, Iraq.

    Human cystic echinococcosis (CE) is a parasitic zoonosis with serious clinical burden and constitutes a challenge to public health in endemic areas worldwide. We performed a retrospective study to investigate the occurrence of CE in patients at six hospitals in Basrah province, Iraq. In the current study setting, data retrieval and validation of the quality of hospital records was very challenging considering the difficult situation Iraq is unfortunately facing. Read More
