Infection, recovery and re-infection of farmed mink with SARS-CoV-2.

Mink, on a farm with about 15,000 animals, became infected with SARS-CoV-2. Over 75% of tested animals were positive for SARS-CoV-2 RNA in throat swabs and 100% of tested animals were seropositive. The virus responsible had a deletion of nucleotides encoding residues H69 and V70 within the spike protein gene as well as the A22920T mutation, resulting in the Y453F substitution within this protein, seen previously in mink.

RT-qPCR assay for detection of mink astrovirus in outbreaks of diarrhea on Danish mink farms.

Diarrhea in mink kits is a major cause of disease and mortality in the mink production. The etiology remains unknown in most outbreaks due to a lack of diagnostic assays. In the current study we present an RT-qPCR method to detect mink astrovirus in fecal samples from mink kits with diarrhea.

SARS-CoV-2 in Danish Mink Farms: Course of the Epidemic and a Descriptive Analysis of the Outbreaks in 2020.

SARS-CoV-2 infection is the cause of COVID-19 in humans. In April 2020, SARS-CoV-2 infection in farmed mink () occurred in the Netherlands. The first outbreaks in Denmark were detected in June 2020 in three farms.

SARS-CoV-2 Transmission between Mink (Neovison vison) and Humans, Denmark.

Severe acute respiratory syndrome coronavirus 2 has caused a pandemic in humans. Farmed mink (Neovison vison) are also susceptible. In Denmark, this virus has spread rapidly among farmed mink, resulting in some respiratory disease.

Variation in diagnostic NAFLD/NASH read-outs in paired liver samples from rodent models.

Introduction: In animal models of non-alcoholic fatty liver disease (NAFLD), assessment of disease severity and treatment effects of drugs rely on histopathological scoring of liver biopsies. However, little is known about the sampling variation in liver samples from animal models of NAFLD, even though several histopathological hallmarks of the disease are known to be affected by sampling variation in patients. The aim of this study was to assess the sampling variation in multiple paired liver biopsies from three commonly used diet-induced rodent models of NAFLD.
