“After HA activity testing, viral RNA was extracted from the HA-positive allantoic fluid using QIAamp Viral RNA Mini Kit (QIAGEN, Hilden, Germany). Approval for this study was obtained from the Institutional Animal Care and Use Committee at Chungcheongbuk-do Veterinary Service Laboratory (#2019-2) and all experimental procedures from virus isolation to sequencing library preparation were conducted in approved biosafety level 3 (BSL3) facilities (KCDC-12-3-04) at Chungbuk Veterinary Service Laboratory.”
