The role of targeted selective treatments in the development of refugia-based approaches to the control of gastrointestinal nematodes of small ruminants.
Anthelmintic resistance is recognised as a major problem affecting small ruminant production worldwide and now threatens the sustainability of many of these systems. One method that has been proposedExpand

The use of urban sewage sludge on pastures: the cysticercosis threat.
Urban sewage production is increasing and its agronomical use as a fertiliser has been advocated. Considerable defiance is prevalent in consumers and among farmers on the use of such fertilisers dueExpand

Faecal egg count reduction test for assessing anthelmintic efficacy: average versus individually based estimations.
The faecal egg count reduction (FECR) in faeces is the most widely used method to assess the efficacy of anthelmintics against gastrointestinal strongyles. Several methods are used and they yieldExpand

Morphological identification of nematode larvae of small ruminants and cattle simplified.
A simplified system has been developed to facilitate identification of nematode larvae of the common nematodes of cattle, sheep and goats. Firstly, in addition to the characteristics conventionallyExpand

Monitoring the efficacy of ivermectin and albendazole against gastro intestinal nematodes of cattle in Northern Europe.
Faecal egg count reduction tests (FECRT) using ivermectin (IVM) and benzimidazole (BZ) were conducted to investigate the prevalence of anthelmintic resistance in gastro-intestinal nematodes on cattleExpand

Multispecies and multiple anthelmintic resistance on cattle nematodes in a farm in Argentina: the beginning of high resistance?
There are very few resistance records on cattle nematodes. South American successive records have been increasing rapidly since the year 2000. In Argentina, increasing dissatisfaction based on theExpand

Contrasting genetic structures of two parasitic nematodes, determined on the basis of neutral microsatellite markers and selected anthelmintic resistance markers
For the first time, the neutral genetic relatedness of natural populations of Trichostrongylid nematodes was investigated in relation to polymorphism of the β‐tubulin gene, which is selected forExpand

Sheep and goat nematode resistance to anthelmintics: pro and cons among breeding management factors.
Although the molecular bases of resistance to anthelmintic families have been intensively studied, the contributing factors for the development of anthelmintic resistance are less well known. ClearExpand

Population genetic analysis of the ovine parasitic nematode Teladorsagia circumcincta and evidence for a cryptic species.
An understanding of genetic variation in parasite populations, and how it is partitioned, is required to underpin many areas of basic and applied research. Population genetic studies on parasiticExpand
