#Aminoacid #mutations #PB1-V719M and #PA-N444D combined with #PB2-627K contribute to the #pathogenicity of #H7N9 in #mice, Vet Res.: https://veterinaryresearch.biomedcentral.com/articles/10.1186/s13567-024-01342-6
Overall, this study revealed that #virulence in H7N9 is a #polygenic trait and identified novel virulence-related residues (PB2-627K combined with PB1-719M and/or PA-444D) in viral ribonucleoprotein (vRNP) complexes.

2 #aminoacid residues in N-terminal region of #polymerase acidic protein determine #virulence of Eurasian avian-like #H1N1 swine #influenza viruses in mice, J Virol.: https://journals.asm.org/doi/full/10.1128/jvi.01293-24?af=R
We identified that 2 naturally occurring aa mutations in PA derived from #H1N1/2009 are crucial determinants of virulence of rEA H1N1 viruses & revealed differential mechanism by which these 2 mutations affect transcription & replication of vRNA.
-
''It is noteworthy that crucial mutations associated with #mammalian #host #adaptation and enhanced #transmission, specifically residues 271A, 292 V, 591 K, 627 K/V/A, 701N, in PB2 (28, 30, 33-35), and 228S, along with the #virulence-increasing residue 66S in PB1-F2(46), were conspicuously absent in all #HPAI virus strains derived from dairy #cattle and #cats. ''

#Virulence and #transmission vary between #Usutu virus #lineages in #Culex pipiens https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0012295
Therefore, we found evidence of lineage-specific differences in vectorial capacity and virulence to both the vector and vertebrate host which lead to balanced propagation of both viral lineages.

#Outbreaks of #H5N1 High Pathogenicity Avian #Influenza in #SouthAfrica in 2023 Were Caused by Two Distinct Sub-#Genotypes of Clade 2.3.4.4b Viruses, Viruses: https://www.mdpi.com/1999-4915/16/6/896
South African clade 2.3.4.4b H5N1 viruses had comparatively fewer #markers of #virulence and #pathogenicity compared to European strains, a possible reason why no #spillover to #mammals has occurred here yet.

@krypt3ia it is all natural - the real fear is with synthetic attentuation studies - 100x the depression factor and the really sad part is it probably already happened once, likely will happen again #woohan #virulence #unknowns

#PB2 residue 473 contributes to the #mammalian #virulence of #H7N9 avian #influenza virus by modulating viral #polymerase activity via ANP32A, J Virol.: https://doi.org/10.1128/jvi.01944-23
-- In this study, we identified PB2 residue 473 as a new determinant of mouse virulence and mammalian #adaptation of the viral polymerase of the H7N9 virus and its non-pathogenic #H9N2 counterparts.
