The conditions of snail life in African inland waters favour the evolution of microgeographical races while hindering the formation of new species, and the distinctions between many of the bulinid intermediate hosts of Schistosoma are consequently blurred. In this paper the author comments on the distinguishing characters that have been established for the known Bulinus species and subspecies and summarizes the present knowledge of their distribution and importance as intermediate hosts. His work is based on the examination of over 1540 snail samples received at the WHO Snail Identification Centre in Charlottenlund, Denmark.
非洲内陆水域的蜗牛生存条件有利于微地理种群的进化,却阻碍新物种的形成,因此,血吸虫的许多双脐螺中间宿主之间的差异变得模糊不清。在本文中,作者对已确定的已知双脐螺物种和亚种的鉴别特征进行了评论,并总结了它们作为中间宿主的分布及重要性的现有知识。他的工作基于对丹麦夏洛滕隆德世界卫生组织蜗牛鉴定中心收到的1540多个蜗牛样本的检查。
