Fascioliasis Epidemiology in Livestock
Research Guide
What is Fascioliasis Epidemiology in Livestock?
Fascioliasis epidemiology in livestock studies the prevalence, risk factors, transmission dynamics, and control of Fasciola hepatica infections in ruminants using serological and coprological methods.
This subtopic examines Fasciola hepatica infections in cattle and sheep, focusing on intermediate host snails like Lymnaeidae and environmental drivers such as climate and land use. Key studies map global patterns and economic impacts in livestock agriculture. Over 20 papers from the provided list address fascioliasis and helminth epidemiology in ruminants.
Why It Matters
Fascioliasis causes substantial economic losses in livestock production through reduced milk yield, weight gain, and liver condemnation, as quantified in Rodríguez‐Vivas et al. (2017) estimating annual impacts in Mexico cattle. Epidemiological data on snail vectors and transmission inform targeted anthelmintic strategies, highlighted in Cwiklinski et al. (2016) for ruminant fasciolosis control. Mas‐Coma et al. (2018) link livestock infection sources to zoonotic risks, guiding integrated veterinary and public health interventions.
Key Research Challenges
Snail Vector Phylogeny Gaps
Molecular phylogeny of Lymnaeidae, intermediate hosts for Fasciola, remains incomplete despite supermatrix approaches from multiple genes. Correa et al. (2010) sampled worldwide but identified unresolved evolutionary relationships affecting transmission modeling. Accurate vector identification is essential for predicting fascioliasis spread in livestock.
Drug Resistance Emergence
Liver flukes like Fasciola hepatica show increasing resistance to triclabendazole and other anthelmintics in ruminants. Fairweather et al. (2020) review mechanisms in F. hepatica and F. gigantica, complicating control in livestock. Molecular tools for resistance detection lag behind needs in epidemiological surveillance.
Climate Impact Modeling
Land-use changes and climate variability alter snail habitats, driving fascioliasis prevalence in livestock. Hansen and Perry (1994) outline ruminant helminth epidemiology but lack integrated climate models. Recent studies like Roeber et al. (2013) call for advanced tools to forecast transmission risks.
