Participatory surveillance reveals marsh deer mortality event during an extraordinary flood in Ibera Wetlands, Argentina

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Mortality events of marsh deer (Blastocerus dichotomus) have been historically described in the southern margins of its geographical range. Few documented cases show how environmental changes and pathogens interact to trigger mortality scenarios and reveal their causes.

Epidemiological investigation of a severe rumen fluke outbreak on an Irish dairy farm

Parasitology, 2017
AbstractAlthough the rumen fluke,Calicophoron daubneyiis now very common and widespread throughout Western Europe, reports of clinical cases are still rare. This study explores the epidemiological background to a severe rumen fluke outbreak in 6-month-old heifers on a dairy farm in Ireland.

Prevalence of Coccidia and Other Intestinal Parasites in Indigenous Sheep (Ovis aries) in an Agricultural Area in Central Nepal

Veterinary Medicine International, Volume 2025, Issue 1, 2025.
Introduction: Sheep, the multifaceted small ruminants, are vital for meat, milk, wool, manure, skins, and transportation. However, various factors often threaten their sustainability, particularly in lowland areas. Notably, diseases caused by intestinal parasites, particularly coccidian and other helminths, highlight the crucial need for strategic ...

Scanning electron microscopic observations on the tegumental surfaces of two rumen flukes (Trematoda: Paramphistomata) [PDF]

Journal of Helminthology, 1982
ABSTRACTThe surface microtopography ofCalicophoron papillosum(Stiles & Goldberger) andC. calicophorum(Fischoeder), inhabiting the rumen of sheep, has been studied by SEM. InC. papillosum, conspicuous transverse ridges encircle the mid-body, gradually lessening dorsally towards the posterior end.

Biotic interactions in soil and dung shape parasite transmission in temperate ruminant systems: An integrative framework

Ecological Applications, Volume 34, Issue 3, April 2024.
Abstract Gastrointestinal helminth parasites undergo part of their life cycle outside their host, such that developmental stages interact with the soil and dung fauna. These interactions are capable of affecting parasite transmission on pastures yet are generally ignored in current models, empirical studies and practical management. Dominant methods of

Transcriptome analysis of the adult rumen fluke Paramphistomum cervi following next generation sequencing

Gene, 2015
Rumen flukes are parasitic trematodes (Platyhelminthes: Digenea) of major socioeconomic importance in many countries. Key representatives, such as Paramphistomum cervi, can cause "Rumen fluke disease" or paramphistomosis and undermine economic animal productivity and welfare. P.

Identification of factors associated with Fasciola hepatica infection risk areas on pastures via an environmental DNA survey of Galba truncatula distribution using droplet digital and quantitative real‐time PCR assays

Environmental DNA, Volume 6, Issue 1, January–February 2024.
ddPCR‐ and qPCR‐based eDNA assays were developed and applied to survey Galba truncatula on pastureland with the aim of identifying Fasciola hepatica infection risk areas. The likelihood of G. truncatula eDNA presence was lower in habitats that were fully shaded by trees, had black or dark brown soils, and contained deep water pools. The tools developed

Prevalence and Associated Risk Factors of Gastrointestinal Parasite Infections among Meat Goats in Khon Kaen Thailand

Veterinary Medicine International, Volume 2024, Issue 1, 2024.
This study investigated the epidemiology of gastrointestinal (GI) parasite infections among 42 meat goat herds in Khon Kaen, Northeast Thailand, based on 913 fecal samples. The predominant parasites identified in the herd were strongyle (100.0%, 42/42), Trichuris spp. (73.8%, 31/42), Eimeria spp. (66.7%, 28/42), Moniezia spp.

Ruminal Lesions in Dairy Cows Naturally Infected by Calicophoron microbothrioides (Trematoda: Paramphistomidae)

Ciencia y Tecnología Agropecuaria
Calicophoron microbothrioides is a relatively new trematode species reported in domestic ruminants in the Cajamarca Valley (Peru). This species poses a significant endemic risk to domestic ruminants in the local livestock; however, histopathological ...
