Genetic parameters and single-step genome-wide association analysis for trematode (Fasciola hepatica and Calicophoron/Paramphistomum spp.) infections in German dairy cows.

Infections with the liver fluke (Fasciola hepatica) cause economic losses in cattle production worldwide. Also, infections with rumen flukes (Calicophoron/Paramphistomum spp.) are gaining importance in grazing cattle in Europe.

Critical assessment of commercially available microtitre panels for antimicrobial susceptibility testing of veterinary pathogens.

Antimicrobial susceptibility testing (AST) in the veterinary sector by broth microdilution is mainly based on commercially available microtitre plates with specific panels. A critical review of commercially available microtitre panels identified AST panels that fulfil the requirements for obtaining reliable AST results by covering the necessary antimicrobial concentrations for both clinical breakpoints as well as quality control (QC) ranges for approved QC strains. However, there are AST panels in which these prerequisites are only in part fulfilled, and some AST panels that do not fulfil the aforementioned criteria at all.

Ixodes ricinus ticks survive flooding.

Climate-change induced weather extremes like floods are increasing in frequency and intensity, with potential consequences for disease vector ecology. We report on a flooding event during the winter of 2023/2024 in Hanover city, Germany. Our observations demonstrate that I.

Endoparasites of peritoneal organs and skeletal muscles of the European wildcat (Felis silvestris) in Germany.

Background: For several decades, the European wildcat (Felis silvestris) has gradually been returning to the forests of Germany, mainly in the central and southwestern regions. To increase the knowledge about this threatened species, the endoparasite status of dead found specimens from Germany was surveyed.

Methods: A total of 118 wildcats were examined for endoparasites in peritoneal organs and skeletal muscles.

A single treatment with a fluralaner injectable suspension (Bravecto injectable) provides 1-year efficacy against Rhipicephalus sanguineus sensu lato and Ctenocephalides felis in dogs.

Background: Rhipicephalus sanguineus sensu lato (s.l.) and Ctenocephalides felis are among the most important year-round ectoparasites of dogs.

Use of cardiac cell cultures from salmonids to measure the cardiotoxic effect of environmental pollutants.

Environmental stressors such as micro- and nanosized plastic particles (MNPs) or crude oil have a detrimental effect on aquatic animals; however, the impact upon the cardiovascular system of fish remains relatively under-researched. This study presents a novel approach for investigating the effect of crude oil and MNPs on the cardiac system of fish. We used salmonid larvae and cardiac cell cultures derived from hearts of salmonid fish and exposed them to environmental stressors.

poxtA amplification and mutations in 23S rRNA confer enhanced linezolid resistance in Enterococcus faecalis.

Objectives: This study aimed to explore the evolutionary patterns and resistance mechanisms of an Enterococcus faecalis strain harbouring poxtA under linezolid exposure.

Methods: A poxtA-carrying E. faecalis electrotransformant DJH702 with a linezolid minimum inhibitory concentration of 4 mg/L was exposed to increasing concentrations of linezolid (8-64 mg/L).

Temporal dynamics in gastrointestinal helminth infections of sympatric mouse lemur species ( and ) in Northwestern Madagascar.

Madagascar's lemur populations are declining in dwindling habitats due to anthropogenic expansion and changing climatic conditions. Gastrointestinal parasites can be important indicators to assess the health status of threatened species. However, parasites, hosts and the environment are connected in complex interactions.

In vivo anthelmintic activity of Combretum mucronatum schumach & Thonn leaf extract against Haemonchus contortus in goats.

Parasitic infections with gastrointestinal nematodes are a serious problem for the health and welfare of domestic animals and negatively affect the economics of animal production. Haemonchus contortus is a haematophagous nematode of small ruminants responsible for significant mortality and morbidity. In addition, the widespread resistance to synthetic anthelmintic drugs emphasizes the urgent need of alternative treatment options against haemonchosis.

in Wild Boars () in Germany: Serological Screening from Thuringia.

Game meat is an important source of meat borne parasitic infections. Due to its omnivorous diet, the wild boar is an important host of zoonotic parasites such as . can cause severe to fatal disease in immunosuppressed patients, as well as congenital disorders in foetus and neonates.

Endemisation and management of on a beef production farm.

The hard tick transmits a variety of zoonotic pathogens, including , the most common cause of bovine babesiosis in northern Europe. In endemic areas, cattle are rarely clinically affected, as animals up to the age of nine months are resistant against relevant clinical disease and develop protective premunity. However, outbreaks in immunologically naïve herds may lead to considerable losses.

Comparison of morphological and molecular Strongylus spp. identification in equine larval cultures and first report of a patent Strongylus asini infection in a horse.

Background: Surveillance of Strongylus vulgaris and other Strongylus spp. in equids is important for targeted intervention in parasite control, requiring reliable routine diagnostic methods.

Objectives: Comparing morphological examination and PCR analyses of larval cultures to identify Strongylus spp.

Morphological changes in plasma-exposed poultry red mites (Dermanyssus gallinae) using high-resolution video camera and optical coherence tomography (OCT).

Dermanyssus gallinae, the poultry red mite (PRM), is a hematophagous temporary ectoparasite that causes serious economic losses and animal health impairment on laying hen farms worldwide. Control is limited by the parasite's hidden lifestyle, restrictions on the use of chemical acaricides and the development of resistance against certain drug classes. As a result, research was conducted to explore alternative control methods.
