|---|---|---|---|
| 2026-08 | Experimental Infection Pathogenicity Experiment | The PA/PA-X I94V mutation attenuates virulence of H7N9 influenza A virus in chickens. | 42090884 |
| 2026-08 | Zoonotic Surveillance Virus Isolation | Eight H9N2 avian influenza virus strains were successfully isolated from RT‑qPCR–positive chicken samples in Shandong Province, China. | 42184734 |
| 2026-08 | Experimental Infection Pathogenicity Experiment | In PA-X–deficient H7N9 virus, adding the PA I94V mutation has no obvious effect on viral fitness in mice and chickens, implicating PA-X I94V in virulence modulation. | 42090884 |
| 2026-08 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis of poultry-derived H9N2 isolates from Shandong showed a multi-lineage genome composition with PB2 and M from G1-like, PB1/PA/NP/NS from SH/F98-like, and HA/NA from Y280-like lineages, indicating reassortment. | 42184734 |
| 2026-07-22 | Zoonotic Surveillance Serological Evidence | HI assays showed no cross-reactivity between the novel H3 avian influenza viruses and H5, H7, or H9 avian influenza viruses. | 42486182 |
| 2026-07-10 | Zoonotic Surveillance Virus Isolation | Infectious HPAI H5N1 virus (WI5743-H5N1) was recovered following blind passage in embryonated chicken eggs. | 42429628 |
| 2026-05-20 | Experimental Infection Pathogenicity Experiment | Genotype IX Newcastle disease virus strains derived from wild birds were highly pathogenic in experimentally infected chickens, whereas the spotted dove–derived genotype IX strain showed attenuated virulence. | 42159397 |
| 2026-05 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis of the HA gene identified two evolutionary lineages of H7N9 avian influenza virus, Group.y.2.3 and Group.y.2.4, represented by isolates from chicken and quail. | 41747464 |
| 2026-05 | Experimental Infection Pathogenicity Experiment | Group.y.2.3 H7N9 avian influenza virus isolates showed stronger replication and pathogenicity in chickens than other lineages. | 41747464 |
| 2026-05 | Zoonotic Surveillance Virus Isolation | A highly pathogenic H7N9 avian influenza virus isolate, 229-4, was obtained from chicken in China in 2022. | 41747464 |
| 2026-05 | Experimental Infection Host Range Experiment | A chicken-origin H7N9 isolate (229-4) infected mice experimentally, showing avian-to-mammalian cross-species transmission potential. | 41747464 |
