#SARS-CoV-2 #JN1 reveals attenuated #pathogenicity and #airborne #transmission
Source: BioRxIV, AbstractJN.1 is a subvariant of SARS-CoV-2 Omicron BA.2.86 lineage that was predominant worldwide in early 2024, of which the in vivo characteristics are largely unknown. Our results demonstrated that the replication of JN.1 was more efficient than that of the parental BA.2 in Vero cells, which demonstrated low dependence on TMPRSS2. Compared to Omicron variants BA.2 and XBB…

Source: BioRxIV, AbstractThe host range of HPAIV H5N1 was recently expanded to include ruminants, particularly dairy cattle in the United States. Shortly after, human H5N1 infection was reported in a dairy worker in Texas following exposure to infected cattle. Herein, we rescued the cattle-origin influenza…

Source: Nature Communications, AbstractSARS-CoV-2 JN.1 with an additional L455S mutation on spike when compared with its parental variant BA.2.86 has outcompeted all earlier variants to become the dominant circulating variant. Recent studies investigated the immune resistance of SARS-CoV-2 JN.1 but additional factors are speculated to contribute to…

#Hemagglutinin and #neuraminidase of a non-pathogenic #H7N7 avian #influenza virus coevolved during acquisition of intranasal #pathogenicity in #chickens, Arch Virol.: https://link.springer.com/article/10.1007/s00705-024-06118-z
This study demonstrates that viruses that are highly pathogenic when administered intranasally require additional adaptations for increased pathogenicity to be highly lethal to intranasally infected chickens.

H5N1 clade 2.3.4.4b viruses isolated from 2 cats harbored mutations in the PB2 gene encoding single amino acid substitutions E627K or D701N, which are associated with virus adaptation in mammals. We analyzed pathogenicity & transmission of cat-derived viruses in other mammals. Both isolates caused fatal infections in mice & ferrets.
