Abstract

Short-term in vitro pulse-labeling of the free glucose pool in pairs of Schistosoma mansoni, and measurement of the increase in [14C]glucose in the female partner (and the concomitant decrease in the male), has established that glucose can be transferred from male to female schistosomes. It is demonstrated that this transfer is not inhibited by ouabain in S. mansoni. Free glucose levels have been measured in Schistosoma haematobium, Schistosoma japonicum and S. mansoni. Data indicate that the transfer of glucose is not via an active mechanism, but rather the transfer of glucose occurs along a glucose concentration gradient which exists between males and females.

摘要

对曼氏血吸虫配对虫体的游离葡萄糖池进行短期体外脉冲标记,并测量雌性虫体中[14C]葡萄糖的增加量(以及雄性虫体中相应的减少量),已证实葡萄糖可从雄性曼氏血吸虫转移至雌性。结果表明,这种转移在曼氏血吸虫中不受哇巴因抑制。已对埃及血吸虫、日本血吸虫和曼氏血吸虫中的游离葡萄糖水平进行了测量。数据表明,葡萄糖的转移并非通过主动机制,而是沿着雄性和雌性之间存在的葡萄糖浓度梯度进行的。
