We identified 7 species of #coronaviruses, expanding their known host range, & documented cross-species transmission of a novel #canine respiratory coronavirus to raccoon dogs & of #bat HKU5-like CoV to #mink, present at a high abundance in lung tissues. 3 subtypes of #influenza A virus—#H1N2, #H5N6 & #H6N2—were detected in #lungs of guinea pig, mink and #muskrat, respectively.
Major #change in #swine #influenza virus diversity in #France owing to emergence and widespread #dissemination of a newly introduced #H1N2 1C genotype in 2020 http://biorxiv.org/cgi/content/short/2024.07.25.605108v1?rss=1
It was characterized by an HA-1C.2.4, an N2-Gent/84, and internal protein-encoding genes belonging to a newly defined genogroup within the #Eurasian avian-like (EA) #lineage, the EA-DK subclade.

G4 and G5 reassortant EA #H1N1 viruses are the most prevalent in Chinese #pig herds. Clade 6B.1 pdm/09H1N1 viruses were found to be transmitted from humans to pigs. Three new #H1N2 #genotypes were identified using the genomic backbones of G4 or G5 viruses.

Potential pandemic risk of circulating swine H1N2 influenza viruses - Nature Communications
Influenza A viruses pose a continuing pandemic threat to humans. Le Sage, et al. describe a pandemic triage pipeline to evaluate the pandemic risk of emerging viruses and utilize it to characterize two widespread swine influenza A viruses.

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.
Large-Scale Serological Survey of Influenza A Virus in South Korean Wild Boar (Sus scrofa) - PubMed
In this comprehensive large-scale study, conducted from 2015 to 2019, 7,209 wild boars across South Korea were sampled to assess their exposure to influenza A viruses (IAVs). Of these, 250 (3.5%) were found to be IAV-positive by ELISA, and 150 (2.1%) by the hemagglutination inhibition test. Detected …
