“…For example, the life cycles of Schistosoma japonicum and S. mekongi require Oncomelania hupensis and Neotricula aperta as their intermediate hosts, respectively. These snails have limited distributions: N. aperta is endemic to Cambodia, Laos and Thailand [ 59 ], and O. hupensis is found only in China, Indonesia and the Philippines [ 60 ]. Pomacea canaliculata , which is native to South America, was introduced to China in the 1980s and has since replaced Achatina fulica to become a major intermediate host that is the primary cause of A. cantonensis infection in humans in China [ 61 ].…”

BackgroundSnail-borne parasitic diseases, such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis and schistosomiasis, pose risks to human health and cause major socioeconomic problems in many tropical and sub-tropical countries. In this review we summarize the core roles of snails in the life cycles of the parasites they host, their clinical manifestations and disease distributions, as well as snail control methods.Main bodySnails have four roles in the life cycles of the parasites they host: as an intermediate host infected by the first-stage larvae, as the only intermediate host infected by miracidia, as the first intermediate host that ingests the parasite eggs are ingested, and as the first intermediate host penetrated by miracidia with or without the second intermediate host being an aquatic animal. Snail-borne parasitic diseases target many organs, such as the lungs, liver, biliary tract, intestines, brain and kidneys, leading to overactive immune responses, cancers, organ failure, infertility and even death. Developing countries in Africa, Asia and Latin America have the highest incidences of these diseases, while some endemic parasites have developed into worldwide epidemics through the global spread of snails. Physical, chemical and biological methods have been introduced to control the host snail populations to prevent disease.ConclusionsIn this review, we summarize the roles of snails in the life cycles of the parasites they host, the worldwide distribution of parasite-transmitting snails, the epidemiology and pathogenesis of snail-transmitted parasitic diseases, and the existing snail control measures, which will contribute to further understanding the snail-parasite relationship and new strategies for controlling snail-borne parasitic diseases.Electronic supplementary materialThe online version of this article (10.1186/s40249-018-0414-7) contains supplementary material, which is available to authorized users.

Schistosomiasis japonica is an infectious disease caused by Schistosoma japonicum, and it remains endemic in China. Flooding is the main hazard factor, as it causes the spread of Oncomelania hupensis, the only intermediate host of Schistosoma japonicum, thereby triggering schistosomiasis outbreaks. Based on multi-source real-time remote sensing data, we used remote sensing (RS) technology, especially synthetic aperture radar (SAR), and geographic information system (GIS) techniques to carry out warning research on potential snail habitats within the snail dispersal range following flooding. Our research result demonstrated: (1) SAR data from Sentinel-1A before and during a flood were used to identify submerged areas rapidly and effectively; (2) the likelihood of snail survival was positively correlated with the clay proportion, core area standard deviation, and ditch length but negatively correlated with the wetness index, NDVI (normalized difference vegetation index), elevation, woodland area, and construction land area; (3) the snail habitats were most abundant near rivers and ditches in paddy fields; (4) the rivers and paddy irrigation ditches in the submerged areas must be the focused of mitigation efforts following future floods.

“…A ocupação desordenada dos espaços urbanos, associada à alta vulnerabilidade social, como desemprego e baixo poder aquisitivo, e às condições inadequadas de saneamento e moradia, vem causando grande impacto na disseminação de doenças negligenciadas, dentre as quais se destaca a esquistossomose(PEREIRA, 2013).África (HE et al, 2017;CARVALHO et al, 2018;WANG et al, 2018). Esta parasitose é um fator limitante do desenvolvimento econômico e social, e ainda tem grande relevância no contexto da saúde pública, pois estima-se que existam quase 240 milhões de infectados no mundo e que mais de 700 milhões de pessoas se encontram em áreas de endemismo(CHENG et al, 2016;ROCHA et al, 2016; WHO, 2019).No Brasil, a esquistossomose é difundida pela espécie Schistosoma mansoni e acomete cerca de 2,5 a 8 milhões de indivíduos (LIMA et al, 2017). A helmintíase é amplamente distribuída, sendo que a área endêmica se estende do Maranhão até Minas Gerais, e outros focos de transmissão são registrados no Pará, Ceará, Piauí, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Goiás e Rio Grande do Sul (BRASIL, 2017).…”

The influence of natural factors on the spatio-temporal distribution of Oncomelania hupensis

Abstract: The spatio-temporal distribution of O. hupensis was significantly influenced by natural factors, and the influences were heterogeneous across space and time. Additionally, the variation in the spatial-temporal distribution of O. hupensis was mainly affected by rainfall and vegetation.
