First genetic evidence for the presence of the rumen fluke Paramphistomum epiclitum in Pakistan

Parasitology International, 2018
More than 70 species of the Superfamily Paramphistomoidea, have been identified in ruminants in different parts of the world. Most are pathogenic, causing amphistomosis. Adult flukes within this family have a predilection for the forestomach (rumen) or bile duct of the liver, where they may cause epithelial damage.

Parasite‐Mediated Competition Limits Dominant Cervid Competitor

Ecology Letters, Volume 28, Issue 6, June 2025.
We leveraged 2 years of detection/non‐detection data of moose (Alces alces) and white‐tailed deer (Odocoileus virginianus) and parasite loads in faecal samples within a hierarchical abundance‐mediated interaction model to test hypotheses regarding interactions between these cervids and their shared parasites (Parelaphostrongylus tenuis, Fascioloides ...

Fasciola hepatica and Rumen Flukes - In Vitro Evaluation of Main Commercial Anthelmintics

Acta Scientiae Veterinariae, 2023
Background: Trematode infections are of great importance as they affect the health of many species of mammals as cattle, sheep and goat. Fasciola hepatica represents the main trematode zoonosis and risks to human and cattle and paramphistomosis is one emerging parasitic diseases of ruminants widely distributed in the world.

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.

Ostertagia spp ., rumen fluke and liver fluke single- and poly-infections in cattle: An abattoir study of prevalence and production impacts in England and Wales [PDF]

Preventive Veterinary Medicine, 2016
This study aims at investigating the occurrence, risk factors and production impacts on beef carcass parameters of three of the most important cattle helminth infections in England and Wales. Abomasa, reticulorumens and livers from healthy cattle were collected and examined post-mortem quarterly over a one year period in an abattoir in South-West ...

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 ...
