大约 46 种哺乳动物被怀疑是日本血吸虫的储存宿主，因此与最终宿主物种相关的目标寄生虫的踪迹可能具有重要的理论和实际意义。尾蚴出现的昼夜节律是寄生虫适应其最终宿主的一种基因控制行为，似乎是日本血吸虫的完美生物标记。在这项研究中，在中国安徽一个丘陵地区的寄生虫和第一代寄生虫中观察到晚（或夜间）尾蚴出现模式，该地区的啮齿类动物是该地区的宿主。此外，通过循环统计，还证明了寄生虫在此类性状上的同质性。所有这些都为遗传控制的生物特征提供了证据，这对于研究感兴趣的寄生虫传播的宏观或微观动力学似乎至关重要。对于日本血吸虫来说尤其如此，因为此时更有可能存在多种寄生虫分离株或菌株。 (C) 2013 Elsevier Inc. 保留所有权利。
About 46 mammal species have been suspected as reservoir hosts for Schistosoma japonicum and therefore the track of the target parasites, in relation to definitive host species, may be of great importance in terms of theoretical and practical implications. The circadian rhythm of cercariae emergence, a genetically controlled behavior for parasites to adapt to their definitive hosts, may seem to be a perfect biological marker for S. japonicum. In this study, a late (or nocturnal) cercarial emergence pattern was observed on the parasites from one hilly region in Anhui of China, where rodents serve as reservoirs, and on the first generation of the parasites. Moreover, by using the circular statistics, the homogeneity of parasites in such trait was also demonstrated. All these provide evidence for the genetically controlled biological trait, which seems essential in the investigation of macro- or micro-dynamics of parasite transmission of interest. This is particularly true in the case of S. japonicum when multiple parasite isolates or strains are more likely to exist. (C) 2013 Elsevier Inc. All rights reserved.
