I think the most important to answer your question is to make an emphasis that there common species for Schistosoma, Including:

Yes I agreed with my fellow colleagues.

Based on my findings, I know only 26 species of Schistosoma but as of now, only five species infects human. These are S. haematobium, S. japonicum, S. mansoni, S. intercalatum and S. mekongi.. Amidst these five mentioned species, S. haematobium, S. japonicum and S. mansoni are the major human Schistosoma species.

According to research, there are over twenty species of Schistosoma though the remaining species are still being clarified. The three main species infecting humans are Schistosoma haematobium, S. japonicum, and S. mansoni. Under S. mansoni are S. edwardiense, S. hippotami, and S. rodhaini. Three other species, more localized geographically, are S. mekongi, S. intercalatum, and S. guineensis. There have also been a few reports of hybrid schistosomes of cattle origin (S. bovis, S. curassoni, S. mattheei) infecting humans. (Centers for Disease Control and Prevention)
