Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

The gastrointestinal nematode Trichostrongylus colubriformis down-regulates immune gene expression in migratory cells in afferent lymph

BMC Immunology, 2010
Background Gastrointestinal nematode (GIN) infections are the predominant cause of economic losses in sheep. Infections are controlled almost exclusively by the use of anthelmintics which has lead to the selection of drug resistant nematode strains.

Metazoan-protozoan parasite co-infections and host body weight in St Kilda Soay sheep [PDF]

, 2008
For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation.

FEC Check: Development of a decision support tool to aid interpretation of gastrointestinal nematode faecal egg counts in sheep

Veterinary Record, EarlyView.
Abstract Background Gastrointestinal nematode infections are ubiquitous in grazing livestock worldwide impacting animal health and production. Faecal egg count (FEC) is an accessible diagnostic test that can guide the need for treatment. However, interpretation of FECs can be challenging.

Genetic regulation of parasite infection: empirical evidence of the functional significance of an IL4 gene SNP on nematode infections in wild primates

Frontiers in Zoology, 2011
Background Susceptibility to parasite infection affects fitness-related processes, such as mate choice and survival, yet its genetic regulation remains poorly understood.

A study on some aspects of the pathogenicity, diagnosis and control of gastrointestinal nematodes in deer : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science at Massey University, Palmerston North, New Zealand [PDF]

, 2017
The most important parasites in farmed red deer are Dictyocaulus eckerti and gastrointestinal nematodes (GIN). The overall aim of these studies was to develop an understanding about GIN parasites in red deer, including their pathogenicity, diagnosis ...

‘Reservoir dogs’: The emerging zoonotic risk associated with European dog imports to the UK

Veterinary Record, EarlyView.
Abstract Background The movement of dogs from continental Europe to the UK poses a growing public health threat due to the associated risk of disease incursions. Current legislation is insufficient to address the risks and pre‐import control measures are focused only on rabies virus and the fox tapeworm Echinococcus multilocularis. Methods We conducted

Wild ruminants as reservoirs of domestic livestock gastrointestinal T nematodes [PDF]

, 2020
Gastrointestinal nematode (GIN) infections in cattle cause appetite suppression which leads to poor feed conversion, reduced weight gain and reduced milk production.

Caenorhabditis elegans muscle Cys-loop receptors as novel targets of terpenoids with potential anthelmintic activity [PDF]

, 2019
The anthelmintic treatment of nematode infections remains the pillar of worm control in both human and veterinary medicine. Since control is threatened by the appearance of drug resistant nematodes, there is a need to develop novel compounds, among which

Risk factors for bark stripping damage on Norway spruce by red deer

Wildlife Biology, EarlyView.
Norway spruce Picea abies is an economically important tree species in Europe, actively managed for forestry. Among the most negative biotic factors for growth and hence forest production is damage caused by wildlife, such as damage through bark stripping by red deer Cervus elaphus.
