Since AIVs could occasionally cause asymptomatic infections in geese, virus monitoring in such a host should be critical to the control of cross-species infection. In addition, previous studies showed that clade 2.3.4.4h H5N6 AIVs could infect mammals without adaptation. However, the pathogenicity and transmissibility of goose-origin clade 2.3.4.4h H5N6 AIVs in mammals remain unknown. In this study, two H5N6 AIVs were isolated from a domestic chicken (A\/chicken\/Hebei CK05\/2019 (H5N6)) and a goose (A\/goose\/Hebei\/GD07\/2019(H5N6)). This study is the first to evaluate the pathogenicity and transmissibility of goose-origin clade 2.3.4.4h H5N6 AIVs in mammals by comparison with chicken-origin 2.3.4.4h H5N6 AIVs. The CK05 virus had an affinity for \u03b1-2,3-receptors, while the GD07 virus had an affinity for both \u03b1-2,3-and \u03b1-2,6-receptors. The GD07 virus had a higher replication capacity in vitro and more severe pathogenicity in mice than the CK05 virus. The CK05 virus could not be transmitted effectively among guinea pigs, whereas the GD07 virus could be transmitted through direct contact among guinea pigs. The results of this study indicated the potential health threat of clade 2.3.4.4h H5N6 AIVs to mammals and emphasized the importance of continuous monitoring of H5N6 AIVs, especially in waterfowl.<\/jats:p>","DOI":"10.3390\/v14112454","type":"journal-article","created":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T03:10:46Z","timestamp":1667790646000},"page":"2454","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pathogenicity and Transmissibility of Goose-Origin H5N6 Avian Influenza Virus Clade 2.3.4.4h in Mammals"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3049-1587","authenticated-orcid":false,"given":"Cheng","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine, Hebei Agricultural University, Baoding 071000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huan","family":"Cui","sequence":"additional","affiliation":[{"name":"Changchun Veterinary Research Institute, Chinese Academy of Agriculture Sciences, Changchun 130122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ligong","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Hebei Agricultural University, Baoding 071000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wanzhe","family":"Yuan","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Hebei Agricultural University, Baoding 071000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shishan","family":"Dong","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Hebei Agricultural University, Baoding 071000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunyi","family":"Kong","sequence":"additional","affiliation":[{"name":"Changchun Veterinary Research Institute, Chinese Academy of Agriculture Sciences, Changchun 130122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhendong","family":"Guo","sequence":"additional","affiliation":[{"name":"Changchun Veterinary Research Institute, Chinese Academy of Agriculture Sciences, Changchun 130122, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juxiang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Hebei Agricultural University, Baoding 071000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1244","DOI":"10.3201\/eid1608.091540","article-title":"Scavenging ducks and transmission of highly pathogenic avian influenza, Java, Indonesia","volume":"16","author":"Henning","year":"2010","journal-title":"Emerg.
