Abstract：
:Mixed infections with Schistosoma japonicum and S. mansoni were carried out in mice. S. japonicum females paired with S. mansoni males developed normally and produced numerous viable eggs; very little sperm was found in the female genital tract. The eggs yielded many miracidia infective to Oncomelania hupensis, the host of S. japonicum. Cercariae arising from miracidia developed into male worms with an electrophoretic pattern of malate dehydrogenase (MDH) corresponding only to the maternal species S. japonicum. S. mansoni females paired with S. japonicum produced few viable eggs; sperm was found in the female genital tract. Miracidia hatched from some of these eggs were infective to Biomphalaria glabrata, the host of S. mansoni. Cercariae arising from miracidia developed into female worms with an electrophoretic pattern of MDH typical of the maternal species S. mansoni. It was concluded that S. japonicum females paired with S. japonicum males reproduce parthenogenetically. Parthenogenesis in schistosomes is discussed.
