摘要
描述了Hypoderaeum conoideum（棘皮动物门：Echinostomatidae）不同幼虫阶段的形态和生命周期。淡水螺类 Lymnaea peregra（腹足纲：Lymnaeidae）是自然的第一中间宿主，它和 L. corvus 是实验的第一中间宿主。这些蜗牛和其他淡水蜗牛（如 Physella acuta 和 Gyraulus chinensis）则作为第二中间宿主。成虫可从小鸡和鸭身上获得，但不能从大鼠、小鼠和金仓鼠身上获得。幼虫阶段的形态与之前研究 H. conoideum 的结果进行了比较。描述了生活史阶段生物学的几个方面，重点是自由生活阶段的传播动态。研究和讨论了可能作为第一和/或第二中间宿主的蜗牛物种的不同适宜性。
The life cycle and transmission dynamics of the larval stages of Hypoderaeum conoideum
The morphology of the different larval stages and life cycle of Hypoderaeum conoideum (Trematoda: Echinostomatidae) are described. The freshwater snail species Lymnaea peregra (Gastropoda: Lymnaeidae) serves as the natural first intermediate host and this and L. corvus serve as experimental first intermediate hosts. These and other freshwater snails, such as Physella acuta and Gyraulus chinensis, in turn serve as second intermediate hosts. Adult worms were obtained from chicks and ducks, but not from rats, mice and golden hamsters. The morphology of the larval stages is compared with previous work on H. conoideum. Several aspects of the biology of the life history stages are described with emphasis on the transmission dynamics of the free-living stages. Differential suitability of the snail species that may act as first and/or second intermediate hosts is studied and discussed.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
