以螺宿主或血吸虫幼虫为目标的血吸虫病防制措施,可从较多地了解毛蚴和尾蚴怎样发现和钻进宿主的复杂情况而得到提高。以往的研究证实了哺乳动物皮肤产生的化学物质能引起曼氏血吸虫尾蚴入侵反应。其他的研究提示了氨基酸和其他化合物是对毛蚴的吸引物质,但未说明此种物质是由螺体产生的。本文作者用曼氏血吸虫及扁卷螺Biomphalaria glabrata为材料进行了试验。“有螺水”的制备是将100只扁卷螺放在500毫升泉水中2～3小时,使螺在此期间排 Schistosomiasis control measures aimed at larvae or schistosoma larvae may be enhanced by understanding more about how miracidia and cercariae may find and drill into the host complex. Previous studies have confirmed that chemicals produced in mammalian skin can cause Schistosoma mansoni cercariae invading. Other studies suggest that amino acids and other compounds are attractants of miracidia, but this does not indicate that the substance is produced by spirochetes. The authors tested the Schistosoma mansoni and Biomphalaria glabrata as materials. Preparation of “snail water” is to put 100 flat spiral snail in 500 milliliters of spring water 2 to 3 hours, the snail during this period
