[Study of schistosome-mollusk vector compatibility by the technic of microsurgical transplantation of sporocysts in two Schistosoma japonicum-Oncomelania hupensis combinations originating in mainland China].

The Schistosoma-Mollusc compatibility was tested in two Schistosoma japonicum-Oncomelania hupensis combinations originated from mainland China. The first combination is a combination maintained for more than 30 years in laboratory, the second consisted of a laboratory strain of S. japonicum and a strain of O. h. hupensis taken in the field (Jiangxi province). The fully absence of sporocyst throwing out and hemocyte infiltration 24 h. after transplantation suggest a perfect compatibility of the two combinations. Concerning the test carried out on a natural population of O. h. hupensis, the result obtained might reveal that the schistosomiasis transmission area from Jiangxi province represents focuses with high risk.
