چکیده

This paper is focused on cloning and bioinformatical as well as immunological characterisation of the new vaccine antigen candidate against fasciolosis – Fasciola hepatica phosphoglycerate kinase (FhPGK). The antigen was cloned from the adult fluke by the use of RACE-PCR method. It was found that FhPGK is not a secretory and not a stage specific protein. It is present in all kinds of parasite tissue, particularly in fluke intestine and tegumental as well as subtegumental layers. FhPGK is involved in production of the first ATP molecule in the glycolytic pathway and can be used in vaccination trials in which the strategy is to block fluke`s energy metabolism. This is the first, to date, phosphoglycerate kinase cloned from F. hepatica.

Determination of somatic and excretory-secretory antigens of Fasciola hepatica and Fasciola gigantica using SDS-PAGE

Human fascioliasis due to unknown species and animal fascioliasis caused by both or one of Fasciola spp. are commonly seen in Iran. To compare electrophoretic patterns of somatic and excretory-secretory antigens of F. hepatica and F. gigantica  by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), the adult flukes were collected from infected slaughtered bovine livers. E/S a...

Molecular detection of the infection with Fasciola hepatica in field-collected snails of Galba truncatula and Lymnaea stagnalis from West Azarbaijan, Iran

The liver fluke, Fasciola hepatica, is considered as the most common cause of fasciolosis in both domestic livestock and human. This study was carried out to detect the prevalence of the larval stages of F. hepatica in the snails Galba truncatula and Lymnaea stagnalis in West Azarbaijan, Iran. Snail collection was performed through searching 28 freshwater habitats from May to December 2010. Fol...

Molecular differentiation of sheep and cattle isolates of Fasciola hepatica using RAPD-PCR

Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR) was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected ani...

TGF-β superfamily members from the helminth Fasciola hepatica show intrinsic effects on viability and development

The helminth Fasciola hepatica causes fasciolosis throughout the world, a major disease of livestock and an emerging zoonotic disease in humans. Sustainable control mechanisms such as vaccination are urgently required. To discover potential vaccine targets we undertook a genome screen to identify members of the transforming growth factor (TGF) family of proteins. Herein we describe the discover...

A Consistent PCR-RFLP Assay Based on ITS-2 Ribosomal DNA for Differentiation of Fasciola Species

  Objective(s): Fascioliasis is a zoonotic parasitic disease caused by liver fluke species of Fasciola hepatica and Fasciola gigantica. Differentiation of these two species, based on their morphological characteristics, is difficult. The current study aimed to use PCR-RFLP assay to distinguish between F. hepatica and F. gigantica , based on profiles of RFLP, produced by effect of endo...
