Taxonomic Confusion Regarding the Intermediate Host of Schistosoma mansoni in China: A Review of Studying on Biomphalaria straminea Complex Classification - Abstract
The Biomphalaria populations that distribute in Guang Dong province, China, include Biomphalaria straminea and Biomphalaria kuhniana. These two species, together with Biomphalaria intermedia, have been clustered into one group named Biomphalaria straminea complex, for their morphological similarities. However, the different species differ in their compatibility with S. mansoni. B. straminea is susceptible to the fluke, but B. kuhniana and B. intermedia are apparently refractory to infection. The correct identification of this species complex is important, because it is the basis of schistosomiasis transmission. Currently, there are more and more cases that infected with S. mansoni that returning from Africa have been reported in China. Therefore, it’s necessary to summary the studying on B. straminea complex taxonomy, which is helpful to propose intervention and research priorities to tackle the risk of transmission of S. mansoni.
