The efficiency of diamphenethide against Fasciola hepatica in sheep

Studies of the effect of diamphenethide and oxyclozanide on the metabolism of Fasciola hepatica.

Studies were made of the effects of diamphenethide-amine on glucose transport, glycogen breakdown, adenine nucleotides, metabolites and excretory products in both parenchymal and bile duct flukes in vitro and in bile duct flukes in vivo. The most consistent and pronounced effect observed was an elevation of malate levels. There appeared to be no differences between responses of parenchymal and ...

Sheep and Fasciola hepatica in Europe: the GLOWORM experience.

Fasciola hepatica infection challenges health, welfare and productivity of small ruminants throughout the world. The distribution of F. hepatica in sheep in Europe is usually scattered and studies are generally concerned with a single area making it difficult to compare results from different environments, climates and management regimes. In order to elucidate the current scenario in terms of p...

Local immune response to experimental Fasciola hepatica infection in sheep.

Macrophages, eosinophils, neutrophils and lymphocyte subpopulations (OvCD5+, OvCD4+, OvCD8+, OvWC1+ and lg+) were identified in sections of hepatic tissue and hepatic lymph nodes from sheep experimentally infected with F. hepatica and necropsied 14, 28, 42 or 56 days post infection. The migratory tunnels produced by juvenile flukes appeared as local areas of necrosis surrounded by infiltrating ...

Fasciola hepatica

18 The success of helminth parasites is partly related to their ability to modulate host immune 19 responses towards an anti-inflammatory/regulatory phenotype. This ability resides with the 20 molecules contained in the secretome of various helminths that have been shown to interact with 21 host immune cells and influence their function. Consequently, there exists a unique opportunity 22 to exp...

Responses of Fasciola hepatica infected sheep to various infection levels.

The response to Fasciola hepatica was studied in sheep infected with 5, 30, 150 metacercariae. The animals were necropsied 12 weeks post-infection (p-i) for counting and measuring flukes. Cellular and humoral responses were detected by peripheral eosinophil count, peripheral blood lymphocyte proliferation with excretory-secretory products (FhESP) and ELISA. All sheep were infected at necropsy e...
