AIMS
We investigated the presence of SARS-CoV-2 in free-ranging wildlife populations in Northeastern Minnesota on the Grand Portage Indian Reservation and Isle Royale National Park.
METHODS AND RESULTS
One hundred twenty nasal samples were collected from white-tailed deer, moose, grey wolves and black bears monitored for conservation efforts during 2022-2023. Samples were tested for viral RNA by RT-qPCR using the CDC N1/N2 primer set. Our data indicate that no wildlife samples were positive for SARS-CoV-2 RNA.
CONCLUSIONS
Continued surveillance is therefore crucial to better understand the changing landscape of zoonotic SARS-CoV-2 in the Upper Midwest.
目的
我们调查了明尼苏达州东北部大波特盖奇印第安保留地和皇家岛国家公园的野生动物种群中是否存在 SARS-CoV-2。
方法和结果
2022-2023 年，我们从白尾鹿、驼鹿、灰狼和黑熊等受保护的野生动物身上采集了 120 份鼻腔样本。使用疾控中心 N1/N2 引物集，通过 RT-qPCR 对样本进行病毒 RNA 检测。我们的数据表明，没有野生动物样本的 SARS-CoV-2 RNA 呈阳性。
结论
因此，持续监测对于更好地了解中西部地区人畜共患 SARS-CoV-2 的不断变化的情况至关重要。
