First #detection of #influenza A virus subtypes #H1N1 and #H3N8 in the #Antarctic region: King George Island, 2023
Source: Vopr Virusol., AbstractRelevance. Influenza A virus is characterized by a segmented single-stranded RNA genome. Such organization of the virus genome determines the possibility of reassortment, which can lead to the emergence of new virus variants. The main natural reservoir of most influenza A virus subtypes are wild waterfowl. Seasonal migrations…

by screening the global PB2 seq., we discovered a new independent cluster with PB2-627V emerged in the '10s, which is prevalent in various avian, mammalian, & human isolates of AIVs, including #H9N2, #H7N9, #H3N8, 2.3.4.4b #H5N1, and other subtypes.

#Adaptation potential of #H3N8 canine #influenza virus in #human respiratory #cells, Sci Rep.: https://www.nature.com/articles/s41598-024-69509-x
We found that CIV acquired high growth properties in these cells mainly through #mutations in surface #glycoproteins, such as hemagglutinin (#HA) and neuraminidase (#NA). Our reverse genetics approach revealed that HA2-K82E, HA2-R163K, and NA-S18L mutations were responsible for the increased growth of CIV in human cells.

Detected subtypes included 23 cases of pandemic 2009 #H1N1, six of human seasonal #H3N2, three of classical swine H1N1, 13 of triple-reassortant swine #H1N2, seven of triple-reassortant swine H3N2, and seven of swine-origin H3N2 variant. Notably, none of the serum samples tested positive for avian IAV subtypes #H3N8, #H5N3, #H7N7, and #H9N2 or canine IAV subtype H3N2.

With its wide geographical distribution and continuing evolution in chickens, other spillovers to humans can be expected and might lead to more efficient transmission in humans.''
