Studies on the liver fluke fasciola morphometrical studies

ABSTRACT

A comparative scanning electron microscopy and morphometric study of the two geographically isolated species of Fasciola [F. heptica European isolate and F. gigantica from Egypt] was studied in order to Clarify their genetic relationships and specific identification. Although the present study revealed that most of the diagnostic morphological and morphometric 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. gigantica
