Dear Calvin,

Several wild and domestic animal are potential host ( and reservoir) of species of Schistosoma that infect humans.  For a compilation of reports related to occurence of S. mansoni in animals from Brazil, please see the attached file.

Best regards from Brazil

yes ,i agree with mala

Dear Calvin,

Yes, I added a reference more that can be helpful.

Good luck,

THANKS A LOT. ALL YOUR INFORMATION HAS BEEN USEFUL

I study fluke Orientobilharzia turkestanica - parasites of mammals. Since these species are infected by about 20 species of mammals. Among them are wild mammals. For example, Saiga tatarica, Capreolus capreolus, Sus scrofa. Orientobilharzia is akin genus Schistosoma. Therefore, definitely infected with schistosomes too wild mammals.

Dear Calvin,

Schistosoma as a genus is quite diverse in terms of host specificity, and more work needs to be done on geographical variation in this regard.  In general there are some general trends, however.  All known species will infect some other mammalian hosts in nature and experimentally.  S. haematobium generally is more host specific than S. mansoni or S. japonicum.  Variations occur among other human (S. mekongi and S. intercalatum) and non-human animal species as well, and the same is true for other mammalian and avian schistosomatids.  Recent work in East Africa is revealing a possibly greater involvement oof rodents as potential reservoirs for S. mansoni, and our knowledge of the zoonotic aspects of schistosomiasis will undoubtedly continue to grow as more research is done.

Good luck with your work on this important topic.

 I agree , there are some species of Schistosoma genus infecting animals

with best wishes for all

Historically it was thought that human schistosomes only infect humans and cattle schistosomes only infect cattle; remaining as distinct, conserved species. However initial studies, conducted on schistosomes obtained from both human definitive hosts and snail intermediate hosts (Leger, 2015). According to the study conducted by Stefano Catalano, Mariama Sène, Nicolas D Diouf, Cheikh B Fall, Anna Borlase, Elsa Léger, Khalilou Bâ, and Joanne P Webster ,They elucidated the role of wild small mammals as reservoir for zoonotic Schistosoma species and hybrids in endemic areas of Senegal. They identified Schistosoma mansoni, Schistosoma bovis, and a Schistosoma haematobium/S. bovis hybrid, with local prevalence in wild rodents ranging from 1.9% to 28.6%. Thier findings indicate that rodents may be an important local reservoir for zoonotic schistosomiasis in endemic areas of West Africa, amplifying transmission to humans and acting as natural definitive hosts of schistosome hybrids. ( Catelano, et. al) Their studies shows that there are a number of reservoir hosts capable of carrying Schistosoma spp. These include monkeys, cattle and other livestock, rodents and domesticated animals such as dogs and cats. (Zeibig, 2013)

Yes. Schistosoma spp. can be transmitted to different species of animals including wild mammals to serve as its reservoir host. Based on the examination of domestic and wild animals for natural infection with human schistosomiasis in Northern Gezira, Sudan, Schistosoma mansoni worms were found on two cattles. Rhesus monkey, hamster, opossum gerbil, sheep, goats, and rodent specifically Hybomys univitatus were found to be infected with Schistosoma intercalatum. Moreover, Philippines was said to be endemic for schistosomiasis caused by Schistosoma japonicum in which dogs, pigs, rats, water buffalo, etc. are potentially important reservoir hosts for the parasite.
