Two fractions were isolated from coproantigen by ion-exchange chromatography in which DEAE cellulose was utilized. Both fractions and crude antigen were characterized by SDS-polyacrylamide gel electrophoresis which revealed 13 bands of molecular weight ranged from 205-31 in crude coproantigen. While fraction I resolved into six bands of molecular weight 198, 178, 148, 111, 101 & 45. Fraction II...

abstract background: we aimed to describe morphological and morphometrical characteristics of fasciola spp. in livestock from ardabil province, northwest iran. methods: forty adult flukes were collected from different definitive hosts (cattle and sheep). previously specimens were identified as f. hepatica or f. gigantica based on pcr-rflp of the its-1 region with rsai enzyme.  we identified fas...

Fasciolosis, a food-borne trematodiasis, results following infection with the parasites, Fasciola hepatica and Fasciola gigantica. These trematodes greatly affect the global agricultural community, infecting millions of ruminants worldwide and causing annual economic losses in excess of US $3 billion. Fasciolosis, an important zoonosis, is classified by WHO as a neglected tropical disease with ...
