The aim of this research was to compare excretory-secretory and somatic extract materials of and to detect protein maps of two species.Twenty infected livers were collected from sheep in industrial slaughterhouse in Tehran, 2017-2019. Worms were detached from bile ducts, then recognized according to morphologic and morphometric criteria. After three times washing, worms were incubated in RPMI culture media and excretory-secretory products were collected. Worms were crushed and homogenized for preparation of somatic extract. Two Dimensional Electrophoresis gels were accomplished for both excretory-secretory material and somatic extracts. Gels were scanned with densitometer and analyzed with Same Spots software and protein spots were identified with Expasy database.For both excretory-secretory products and somatic extract, protein spots were appeared with two-dimensional electrophoresis technique. Quantitative analysis showed 40 and 28 protein spots for excretory-secretory of and respectively. For somatic extract 19 and 12 protein spots were recognized for and in that order.The rate of expression of some proteins were more in while expression of other proteins was high in . The expression of protease enzyme was higher in than . These data could be considered for biochemical differentiation of species and subsequently to design and prepare of antigens for diagnosis/vaccine development.
