Fasciola hepatica is an important trematode parasite of economic importance that infests sheep and cattle worldwide. We conducted a detailed investigation into the spatial distribution of F. hepatica infestation in farmed sheep in Qinghai (Wutumeiren) province, Mainland China. Mathematical modelling was used to assess the inter-relationships between meteorological and geographical factors and t...

Fascioliasis is an emerging and important chronic parasitic disease caused by two trematode liver fluke species: Fasciola hepatica (F. hepatica) and Fasciola gigantica (F. gigantica) infecting several herbivorous mammals including cattle, goats, sheep, and humans. We report a 9-year-old girl who suffered from F. hepatica infection and underwent right hepatectomy because of increasing abdominal ...

OBJECTIVES The trematocidal properties of a synthetic peroxide, 1,2,4-trioxolane (OZ78) were determined both in vivo and in vitro. METHODS Two weeks post-infection Echinostoma caproni-infected mice were administered single oral doses of 400-1000 mg/kg OZ78. Fasciola hepatica-infected rats were treated orally with 50-400 mg/kg OZ78 3 and 8-9 weeks post-infection. Worm burden reductions were as...

The liver fluke Fasciola hepatica is a trematode parasite with a worldwide distribution and is the cause of important production losses in the dairy industry. The aim of this observational study was to assess the prevalence of exposure to F. hepatica in a group of high yielding dairy herds, to determine the risk factors and investigate their associations with production and fertility parameters...

BACKGROUND Fasciola hepatica is a parasite with a significant impact on ruminant livestock production. Previous studies in north-west Europe have described its geographical distribution and determined potential predictors of fasciolosis using geographical information system (GIS) and regression modelling. In Sweden, however, information about the distribution of fasciolosis is limited. This stu...

Fasciola hepatica tegument antigens were isolated from intact worms in the cold by using Nonidet P-40. Proof of the tegumental nature of the antigens was shown by the peroxidase-antiperoxidase immunocytochemical technique at the light microscope level. The potential of F. hepatica tegument antigens for the immunodiagnosis of rabbit and human fascioliasis was shown by Ouchterlony immunodiffusion...

Background and purpose: Fasciola hepatica and Fasciola gigantica are common liver flukes that are the etiological agents of fasciolosis, which affects both domestic livestock and humans worldwide. In the present study we established a rapid, easy and also accurate tool, for differentiation between F. hepatica and F. gigantica using Fast PCR. Material and methods: Thirty adults of Fasciola spec...

Fascioliasis, a food-borne trematode zoonosis, is a disease primarily in cattle and sheep and occasionally in humans. Water dropwort (Oenanthe javanica), an aquatic perennial herb, is a common second intermediate host of Fasciola, and the fresh stems and leaves are widely used as a seasoning in the Korean diet. However, no information regarding Fasciola species contamination in water dropwort i...

Fasciolosis, like other helminth infections, is associated with the induction of T-cell responses polarized to the Th2 subtype. Respiratory infection with Bordetella pertussis or immunization with a pertussis whole-cell vaccine (Pw) induces a potent Th1 response, which confers a high level of protection against bacterial challenge. We have used these two pathogens to examine bystander cross-reg...

Paramphistomosis and Fasciolosis caused by Calicophoron daubneyi and Fasciola hepatica, respectively, are frequent and important trematodoses in ruminant livestock worldwide. Both parasites use the same snail, Galba truncatula, as intermediate host. The aim of this study was to develop and validate an analytical method based on a mitochondrial DNA (mtDNA) multiplex PCR technique which would all...
