longitudinal study on the temporal and micro-spatial distribution of galba truncatula in four farms in belgium as a base for small-scale risk mapping of fasciola hepatica.the trematode parasite fasciola hepatica causes important economic losses in ruminants worldwide. current spatial distribution models do not provide sufficient detail to support farm-specific control strategies. a technology to reliably assess the spatial distribution of intermediate host snail habitats on farms would be a major step forward to this respect. the aim of this study was to conduct a longitudinal field survey in flanders (belgium) to (i) characterise suitable small water bodies (swb ...201425425397
the use of bulk-tank milk elisas to assess the spatial distribution of fasciola hepatica, ostertagia ostertagi and dictyocaulus viviparus in dairy cattle in flanders (belgium).fasciola hepatica, ostertagia ostertagi and dictyocaulus viviparus are helminth parasites with a wide distribution and an important economic impact in cattle in temperate climates. this paper describes the spatial distribution of f. hepatica, o. ostertagi and d. viviparus in dairy herds in flanders (belgium). one thousand eight hundred herds were selected at random from the flemish dairy population (n=7002), stratified on community level to obtain a sample representative for the entire study are ...200919656630
associations between anti-fasciola hepatica antibody levels in bulk-tank milk samples and production parameters in dairy herds.our primary objective was to determine the relationships between fasciola-specific antibody levels in bulk-tank milk and measures of productivity to estimate economic losses that are associated with fasciola infections. a bulk-tank milk sample was collected in march 2004 from 1105 dairy herds in flanders and the antibody levels against fasciola hepatica (odrf) and ostertagia ostertagi (odro) were determined. the association of odrf with four production parameters (milk yield, milk-protein %, mil ...200717095109
relative importance of management, meteorological and environmental factors in the spatial distribution of fasciola hepatica in dairy cattle in a temperate climate zone.fasciola hepatica, a trematode parasite with a worldwide distribution, is the cause of important production losses in the dairy industry. diagnosis is hampered by the fact that the infection is mostly subclinical. to increase awareness and develop regionally adapted control methods, knowledge on the spatial distribution of economically important infection levels is needed. previous studies modelling the spatial distribution of f. hepatica are mostly based on single cross-sectional samplings and ...201020887726
