The entire non-sexual reproduction stage in the snail takes 4–6 weeks, but cercariae may be shed for up three months at a rate of dozens (S. japonicum) to thousands (S. mansoni, S. haematobium) per day. While snail life expectancy is reduced by schistosome infection because of damage ...
japonicum II. Life cycle 1. Site of inhabitation: the portal vein system, mainly in the inferior mesenteric vein. 2. ?Infective stage: cercaria 3. ?Infective route: by skin 4. ?Intermediate hosts: Oncomelania snail (钉螺) 5. Reservoir hosts: mammals such as buffalo, cattle, wild rodents,...
(cercariae). Cercariae are released by intermediate snail hosts. There are three major species:Schistosoma mansoni, endemic to Africa, the Eastern Mediterranean, the Caribbean, and South America;Schistosoma haematobium, found in the Middle East and Africa; andSchistosoma japonicum, found in China, ...
The data obtained from each developmental stage were generated by different research teams, different versions of the genomes were employed for mapping, and different approaches were followed for the analyses (see Methods). Notwithstanding these caveats, several GO terms specific to the sporocyst tissues...

japonicum (not shown) as well as human, whose gene products are inferred to be essential and to bind drugs available for treating human diseases. A functional annotation of these 40 kinases showed that 37.5% (n = 1 5) were linked to human ort- hologs that are involved in cancer...
[82]. In total, 98 up-regulated and 133 down-regulated genes were observed in bothS. mekongi- andS. japonicum-infected snails. Interestingly, a decreased expression level of TLR2-encoding genes was observed in our infected snails at a later stage. Our further clustering analysis distinguished ...

(for example,Drosophila,CaenorhabditisandBrugia). Together with the accompanying article onS. japonicum6, we present, to our knowledge, the first descriptions of metazoan genomes from the lophotrochozoan clade. The genome reveals features that aid our understanding of the evolution of complex body ...
the cercariae transform into the first parasitic stage, theschistosomula. The schistosomula enter the bloodstream and migrate via thecirculatory systemthrough the heart and lungs, ultimately reaching themesenteric veins(S. mansoniandS. japonicum) or the veins draining thebladder(S. haematobium). The...
