Abstract
The consistent recovery of schistosome cercariae from turbid water may be an important observation in the study of schistosomiasis transmission. The phototactic behaviour of cercariae was used as the basis of a technique in which cercariae were induced to migrate into a layer of clear water overlying the turbid sample; the clear layer was then filtered and the cercariae counted. The recovery rate, however, does not appear to justify the use of this technique, at least in the field.
摘要
在浑浊水中持续检出血吸虫尾蚴可能是血吸虫病传播研究中的一项重要发现。利用尾蚴的趋光行为开发了一种技术，即诱导尾蚴迁移到覆盖浑浊样本的一层清水中；然后对清水层进行过滤并计数尾蚴。然而，至少在野外环境中，这种技术的回收率似乎并不足以证明其使用价值。
