“…All samples were individually crushed using a bead mill in an enzyme-free Eppendorf tube with 1-mm-diameter inox beads (Qiagen, Germany). After removing the beads, we extracted total DNA using the hipure DNA mini kit (Magen, China) as previously described ( Lin et al., 2020 ). Briefly, genomic DNA was extracted according to the protocol of the kit, and finally, total DNA was suspended in 30 μl of nuclease-free buffer and stored at −80°C until further processing.…”

“…Biomphalaria snails, including Biomphalaria glabrata and Biomphalaria straminea , are the main intermediate hosts of S. mansoni ( Colley et al., 2014 ). As an important intermediate host of S. mansoni ( Coelho and Caldeira, 2016 ), the freshwater snail B. straminea has invaded Hong Kong, China, since 1974 and has spread widely in South China ( Meier-Brook, 1974 ; Lin et al., 2020 ). In addition, this invasive snail can also transmit the zoonotic parasite Angiostrongylus cantonensis ( Xu et al., 2019 ; Zhu et al., 2019 ).…”

“…In addition, this invasive snail can also transmit the zoonotic parasite Angiostrongylus cantonensis ( Xu et al., 2019 ; Zhu et al., 2019 ). Considering the potential risk of transmission of S. mansoni and threats to human health in China ( Colley et al., 2014 ; Lin et al., 2020 ), it is necessary to pay more attention to monitoring and controlling B. straminea with close surveillance and control strategies.…”

BackgroundSchistosomiasis is one of the most important tropical parasitic diseases worldwide. Biomphalaria straminea, the intermediate host of Schistosoma mansoni, has invaded and spread to Southern China since 1974 and may pose enormous threats to public health. Controlling intermediate host snails is an effective strategy in schistosomiasis intervention. However, the only effective chemical molluscicide, niclosamide, currently recommended by WHO may cause environmental pollution, loss of biodiversity, and high costs. Thus, to counter intermediate hosts, a sustainable and environmentally friendly tool is urgently needed. Here, we conducted field investigations to collect and identify a potential snail competitor rotifer and evaluated its molluscicide effect.ResultsIn this study, we collected two samples of rotifers from Shenzhen. We found both red and black phenotypic B. straminea snails at the sampling sites. We identified the rotifer population as a species of the genus Philodina according to the amplification and phylogenetic analysis results of coxI gene. We found that rotifer exposure did not significantly affect the hatching rate of B. straminea eggs but promoted the killing of juvenile snails. Meanwhile, rotifer exposure did not significantly alter the fecundity of B. straminea quantified by the number of eggs per egg mass, the number of egg masses per snail, and the number of eggs per snail; but the snails exposed to rotifers showed lower fecundity performance than the control snails. Importantly, rotifer exposure could significantly affect the development of juvenile B. straminea, showing a smaller shell diameter of the exposed snails than that of the control snails. In addition, rotifer exposure affected the life span of B. straminea snails, showing a 16.61% decline in the average life span. After rotifer exposure, the S. mansoni-infected B. straminea snails died significantly faster than those without rotifer exposure. Similar findings were observed in S. mansoni-infected Biomphalaria glabrata snails. These results implied that rotifer exposure significantly promoted the mortality of S. mansoni-infected B. straminea and B. glabrata.ConclusionsOur study demonstrated the potential molluscicide effect of rotifers on intermediate hosts under laboratory conditions. Our findings may provide new insights into the development of biocontrol strategies for snail-borne disease transmission.

“…Previous studies have focused on the biotic and abiotic factors such as temperature, precipitation, elevation, vegetation, water quality, velocity, substrate type [20,[28][29][30][31][32]. Also, some researchers used Geographic Information System and Remote Sensing models to explore the distribution of the B. straminea and predicted their dispersal tendency [33][34][35][36][37]. These studies greatly promoted the understanding of the spread characteristics of the B. straminea.…”

[Background]Schistosomiasis mansoni is one of the most prevalent neglected tropical diseases transmitted by snails of the genus Biomphalaria . The pla norbid freshwater snail Biomphalaria straminea as an invasive vector is expanding its geographic range for its great dispersal capacity in Gonuangdong Province, causing potential risk of an epidemic of S. mansoni in southern China . Previous studies have mainly focus ed on the environmental factors that affect B straminea’ s distribution, but few studies have looked at its hydraulic characteristics for the water conservancy control. This stud y explored its primary parameters of the hydraulics characteristic s including density, hydrostatic setting velocity and l ocomotion in different water depth to evaluate its peculiar dispersion characteristics in natural environment. [Methods] The density and hydrostatic setting velocity of B. stramine were measured by the drainage volume method and setting tube method, respectively. T he behavior and distribution characteristics of B. stramine in different water depths were observed by the Plexiglas tube method and the effect s of hydrostatic pressure on the climbing speed of B. stramine were also analyzed. [Results] Our results show that the average density of the B. stramine is 1.08 g/cm 3 . The hydrostatic setting velocity of B. stramine is between 2.32 cm/s and 12.92 cm/s in the water , there is no significant difference betwe en the settling velocity and their shape type. In the Plexiglas tubes with different depths, we noted that the locomotion can occur in six manners. The B. stramine distribute mainly along the surface and at the bottom layer of the tubes and the proportion of the B. stramine on the surface water generally raised as time increase d. Also, we observed the climbing speed of B. stramine at different water depth, and obtained the regression equation of the hydrostatic pressure and their climbing speed of the B. stramine . It revealed that the climbing speed of B. stramine increases first and then decreases with the water depth increase, and reaches the maximum when the water depth at 120cm. [Conclusion] The findings of this study indicate that there are si gnificant differen ces between the 50 density , the hydrostatic setting velocity and climbing speed of B. stramine compared with 51 Oncomelania hupensis . Future studies should be conducted more intensive on h ydraulics 52 characteristics of B . straminea and thus establish adequ ate water conservancy measures to control 53 its dispersion

Biomphalaria spp. snails are intermediary hosts of Schistosoma mansoni, etiologic agent of intestinal schistosomiasis, one of the most important neglected tropical diseases. Biomphalaria straminea is an important intermediary host that possess a different phenotype to parasite infection but shows a large geographic distribution and high capacity of new ecologic niche invasion. Our purpose was to characterize for the first time the differentially expressed proteome in B. straminea during two times intervals after primary and secondary exposure to S. mansoni. The hemolymph was collected at 1 and 15 days after primary and secondary exposure of snails to the parasite. Total proteins were extracted and digested with trypsin. LC-MS/ MS label-free quantification was performed and analyzed using Maxquant and Perseus software. Proteins were identified and annotated using Blast2GO tools. After 1 day of exposure, most of upregulated proteins are hemoglobin type 2, C and H type lectins, molecules related to cell adhesion, and response to oxidative stress. After 15 days, we found a similar pattern of upregulated proteins but some fibrinogen-related proteins (FREPs) and TEPs homologs were downregulated. Regarding the differentially expressed proteins during secondary response, the principal immune-related proteins upregulated were C and H type lectins, cellular adhesion molecules, biomphalysin, and FREP3. We noted a several upregulated biological processes during both responses that could be the one of the key points of efficacy in the immune response to parasite. Our data suggests different immune mechanisms used by B. straminea snails challenged with S. mansoni.
