|---|---|---|---|
| 2026-10-08 | Zoonotic Surveillance Virus Isolation | An H9N2 avian influenza virus was isolated from a chicken in Shandong Province, China, in March 2019. | 42849636 |
| 2026-10-08 | Genomic Evolution Phylogenetic Evolution | Both H9N2 isolates were classified as genotype G57 and closely related to H9N2 viruses previously detected in environmental samples in Jiangsu Province. | 42849636 |
| 2026-10 | Experimental Infection Host Range Experiment | In vivo challenge showed the H6N6 avian influenza virus infected mice, SPF chickens, and young Muscovy ducks, causing mild lesions. | 42385378 |
| 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 |
| 2026-07-30 | Experimental Infection Host Range Experiment | H9N2 avian influenza virus replicated and spread more efficiently in chickens than in ducks in controlled poultry infection studies. | 42655013 |
| 2026-07-30 | Experimental Infection Experimental Transmission | H9N2 avian influenza virus was transmitted to contact ducks more efficiently from infected chickens than from ducks to ducks under a controlled contact-transmission setup. | 42655013 |
| 2026-07-30 | Experimental Infection Pathogenicity Experiment | Inoculated chickens and ducks showed upregulated PRR and cytokine mRNA in lungs, with lower fold increases in ducks than chickens following H9N2 infection. | 42655013 |
| 2026-07-30 | Zoonotic Surveillance Virus Isolation | One H9N2 avian influenza virus was isolated from chickens in Jiangsu Province, China in March 2025. | 42655013 |
| 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 |
