“…Yet this pattern is somewhat paradoxical because experimental studies with schistosomes show them to be very specific with respect to the snail species they are able to colonize [38, 71, 72]. How does historical host shifting in snails make sense in light of their evident host specificity we see today?…”

This review provides an update of ongoing efforts to expand our understanding of the diversity inherent within the Schistosomatidae, the parasites responsible for causing schistosomiasis and cercarial dermatitis. By revealing more of the species present, particularly among under-studied avian schistosomes, we gain increased understanding of patterns of schistosome diversification, and their abilities to colonize new hosts and habitats. Schistosomes reveal a surprising ability to switch into new snail and vertebrate host species, into new intra-host habitats, and may adopt novel body forms in the process. Often these changes are not associated with deep splits or long branches in their phylogeny, suggesting they are of relatively recent origin. Several hypotheses prompted by the new observations are discussed, helping to focus thinking on processes influencing not only schistosome diversification, but also their pathogenicity and abundance.

“…Although these snails can tolerate variations in physical, chemical and biological parameters in the environment where they live (Kloos et al, 2001;Utzinger et al, 1997;Woolhouse, 1992), there is a threshold limit for this tolerance. Several biotic and abiotic factors in the environment control Biomphalaria abundance and distribution (Brown, 1994;Rollinson, 2011). Nevertheless, some species of Biomphalaria have proven successful in occupying new ecological niches that in turn led to schistosomiasis expansion, even to non-endemic areas (Sturrock, 1973;Yousif et al, 1996;Lardans and Dissous, 1998;Pointier et al, 2005a;Teodoro et al, 2010).…”

Schistosomiasis is one of the most prevalent parasitic diseases impacting human health in the tropics and sub-tropics. The geographic distribution of Schistosoma mansoni, the most widespread species, includes areas in Africa, the Middle East, South America and the Caribbean. Snails of the genus Biomphalaria act as intermediate host for S. mansoni. Biomphalaria straminea is not indigenous in China but was accidentally introduced to Hong Kong from South America and has spread to other habitats in the southern parts of the country. This species is known for its great dispersal capacity that highlights the importance of the snail as a potential host for S. mansoni in China. In this connection, although no such infection has been recorded in the field so far, the continuous expansion of China's projects in endemic areas of Africa and import of the infection via returning workers or visitors deserve attention. The purpose of this study was to map and predict the spatial distribution of B. straminea in China. Snail occurrence data were assembled and investigated using MaxEnt software, along with climatic and environmental variables to produce a predictive risk map. Of the environmental variables tested, the precipitation of warmest quarter was the most contribution factor for snail's spatial distribution. Risk areas were found in southeastern China and it is expected that they will guide policies and control programmes to potential areas area of snail abundance and used for spatial targeting of control interventions for this invasive species.
