A comparative scanning electron microscopy and morphometrical study of the two geographically isolated species of Fasciola (F. heptica European isolate and F. gigantica from Egypt) were studied in order to clarify their genetic relationships and specific identification. Although the present study has revealed that most of the diagnostic morphological and morphometrical criteria in the two species are highly variable, the position of the ventral sucker relative to the whole body length produced the most significant differentiating criterion, in addition to the presence of markedly larger tegumental papillae on the ventral surface of F. gigiantica.
为了阐明两种地理隔离的片形吸虫（欧洲分离株肝片吸虫和来自埃及的巨片吸虫）之间的遗传关系并进行物种鉴定，对其进行了比较扫描电子显微镜和形态测量学研究。尽管本研究表明，这两个物种的大多数诊断性形态和形态测量标准变化很大，但除了巨片吸虫腹面存在明显更大的体表乳头外，腹吸盘相对于整个体长的位置产生了最显著的区分标准。
