In vitro effects of three woody plant and sainfoin extracts on two parasitic stage of 3 parasitic nematode species [PDF]

open access: yes, 2004
Most studies on the effects of tanniferous plants on nematodes have examined forages but have neglected the woody plants. Therefore, in vitro effects of extracts from 3 woody plants (Rubus fructicosus, Quercus robur, Corylus avellana) have been tested on

RESISTANCE TO ANTHELMINTICS

open access: yesTRAKIA JOURNAL OF SCIENCES
In pasture-raised animals, parasitic infections result in significant financial losses. On the other hand, their prevention and limitation require significant financial resources. Climate change, the existence of causative agents resistant to anthelmintic used for prevention and treatment raise questions requiring focused research under current animal ...

Faecal egg count reduction tests and nemabiome analysis reveal high frequency of multi-resistant parasites on sheep farms in north-east Germany involving multiple strongyle parasite species

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance
Anthelmintic resistance in sheep parasitic gastrointestinal nematodes is widespread and a severe health and economic issue but prevalence of resistance and involved parasite species are unknown in Germany. Here, the faecal egg count reduction test (FECRT)

Incidence of anthelmintic resistance in cattle farms in Northern Germany – first results [PDF]

open access: yes, 2008
Anthelmintic resistance (AR) is an increasing problem worldwide especially for small ruminants and it is also rising in cattle. To maintain the efficacy of anthelmintics is an important objective.

Effect of sainfoin (Onobrychis viciifolia) silage and hay against gastrointestinal nematodes in lambs [PDF]

open access: yes, 2007
The objective of the study was to examine the effect of dried and ensiled sainfoin (Onobrychis viciifolia) against two species of gastrointestinal nematodes (Haemonchus contortus, Cooperia curticei) in lambs. Twenty-four days post experimental infection,

Anthelmintic resistance in cattle [PDF]

open access: yes, 2019
Parasitic nematode infections can affect all ages of cattle, but are mainly of clinical significance in young parasite-naïve calves in their first year at grass, or in second-year grazers (Figure 1). For these animals, several control and worming strategies have been advocated that have proved successful – particularly since the launch of the ...

Metabolomic and proteomic differences in susceptible and benzimidazole-resistant adult females and males of Haemonchus contortus

open access: yesVeterinary Research
Anthelmintic resistance in parasitic nematodes, particularly in Haemonchus contortus, poses a significant threat to livestock health and productivity. Since resistance mechanisms have not yet been fully elucidated, the present study employed metabolomic ...
