There is some confusion regarding the differentiation of African and Middle Eastern schistosomes with terminal-spined eggs. In an attempt to clarify the situation, the author has separated the members of the genus Schistosoma that have terminal-spined eggs into three broad groups and five species on the basis of egg morphology and certain biological characteristics.THE GROUPS ARE: the haematobium group, with one species (S. haematobium); the bovis group, with three species (S. bovis, S. mattheei and S. leiperi); and the intercalatum group, with one species (S. intercalatum). Further species separation is not thought to be justified yet, and reasons are given for considering S. capense and S. curassoni as synonymous with S. haematobium and S. mattheei respectively.
关于具有端刺虫卵的非洲和中东血吸虫的鉴别存在一些混淆。为了澄清这种情况,作者根据虫卵形态和某些生物学特征,将具有端刺虫卵的血吸虫属成员分为三大类和五个物种。这三大类分别是:埃及血吸虫组,包含一个物种(埃及血吸虫);牛血吸虫组,包含三个物种(牛血吸虫、马氏血吸虫和莱氏血吸虫);间插血吸虫组,包含一个物种(间插血吸虫)。目前认为进一步的物种细分尚无充分理由,并给出了将开普血吸虫和库拉索血吸虫分别视为埃及血吸虫和马氏血吸虫同义词的理由。
