Adaptation, spread and transmission of SARS-CoV-2 in farmed minks and associated humans in the Netherlands


Posted: 2021-11-24 20:00:00
In the first wave of the COVID-19 pandemic (April 2020), SARS-CoV-2 was detected in farmed minks and genomic sequencing was performed on mink farms and farm personnel. Here, we describe the outbreak and use sequence data with Bayesian phylodynamic methods to explore SARS-CoV-2 transmission in minks and humans on farms. High number of farm infections (68/126) in minks and farm workers (>50% of farms) were detected, with limited community spread. Three of five initial introductions of SARS-CoV-2 led to subsequent spread between mink farms until November 2020. Viruses belonging to the largest cluster acquired an amino acid substitution in the receptor binding domain of the Spike protein (position 486), evolved faster and spread longer and more widely. Movement of people and distance between farms were statistically significant predictors of virus dispersal between farms. Our study provides novel insights into SARS-CoV-2 transmission between mink farms and highlights the importance of combining genetic information with epidemiological information when investigating outbreaks at the animal-human interface.

ヒトY染色体遺伝子によって制御される非性器機能が発見された。なぜ特定の病気が男性と女性に異なる影響を与えるのか?その理由を解明できるかもしれない。

男性特有のY染色体遺伝子のあまり知られていない役割に新たな光が当てられ、 COVID-19 を含むさまざまな病気で、男性が女性とは異なる重症化を示すのか理由を説明することができるかもしれない。この研究成果は、モントリオール大学・モントリオール臨床研究所の実験的心臓血管生物学研究ユニットのディレクターであるChristian Deschepper医学博士によって、Scientific Reports…
