Schmallenberg Virus, from the Necropsy Room to the Laboratory.

In a world facing significant climate changes, arboviruses are expanding into new regions. In recent decades, Western Europe has experienced multiple outbreaks of epizootic arboviruses in ruminants, including the Schmallenberg virus. This virus emerged in 2011 and spread rapidly across the continent, causing severe malformations in the central nervous systems of ruminant fetuses.

Longitudinal quantitative assessment of TMEV-IDD-induced MS phenotypes in two inbred mouse strains using automated video tracking technology.

Multiple sclerosis (MS) is a chronic disabling disease of the central nervous system affecting over 2.5 million people worldwide. Theiler's murine encephalomyelitis virus-induced demyelinating disease (TMEV-IDD) is a murine model that reproduces the progressive form of MS and serves as a reference model for studying virus-induced demyelination.

A timely, user-friendly, and flexible marker-assisted speed congenics method.

Mice are the most widely used mammalian animal model worldwide. Their use presents many advantages, including our ability to manipulate their genome. Unfortunately, transgenic mice often need to be introgressed to transfer the transgene of interest in a specific mouse line.

Anti-Schmallenberg Virus Activities of Type I/III Interferons-Induced Mx1 GTPases from Different Mammalian Species.

Mx proteins are key factors of the innate intracellular defense mechanisms that act against viruses induced by type I/III interferons. The family Peribunyaviridae includes many viruses of veterinary importance, either because infection results in clinical disease or because animals serve as reservoirs for arthropod vectors. According to the evolutionary arms race hypothesis, evolutionary pressures should have led to the selection of the most appropriate Mx1 antiviral isoforms to resist these infections.

SARS-CoV-2 Natural Transmission from Human to Cat, Belgium, March 2020.

In March 2020, a severe respiratory syndrome developed in a cat, 1 week after its owner received positive test results for severe acute respiratory syndrome coronavirus 2. Viral RNA was detected in the cat's nasopharyngeal swab samples and vomitus or feces; immunoglobulin against the virus was found in convalescent-phase serum. Human-to-cat transmission is suspected.
