|---|---|---|---|
| 2026-07-18 | Experimental Infection Pathogenicity Experiment | Intramammary inoculation with influenza A(H5N1) in lactating sows caused mammary lesions and antigen-positive tissue with sustained viral RNA in milk but no overt clinical disease or respiratory involvement. | 42523357 |

| 2026-07-18 | Experimental Infection Experimental Transmission | Piglets co-housed with intramammary-inoculated lactating sows showed sporadic oral viral RNA positivity that mirrored milk viral kinetics, indicating limited vertical transmission to piglets. | 42523357 |
| 2026-07-02 | Experimental Infection Host Range Experiment | Porcine deltacoronavirus (PDCoV) can infect pAPN-knockout cell lines and pigs, indicating susceptibility even without pAPN. | 42390253 |
| 2026-07 | Experimental Infection Host Range Experiment | VSV-based African swine fever virus pseudoviruses with different envelope protein compositions showed distinct species- and cell-type specific entry tropism in PAMs, Vero, and BHK-21 cells. | 42105932 |
| 2026-06-27 | Zoonotic Surveillance Viral Detection | RT-qPCR detected swine influenza virus in 1 of 600 pig nasal swabs collected in Shandong Province. | 42365259 |
| 2026-06-27 | Zoonotic Surveillance Virus Isolation | An H3N2 swine influenza virus, designated A/swine/Shandong/116/2022 (H3N2), was successfully isolated from a positive pig sample using 10-day-old SPF embryonated chicken eggs. | 42365259 |
| 2026-06-11 | Functional Mechanism Receptor Usage | Transmissible gastroenteritis virus (TGEV) uses aminopeptidase N (ANPEP) as its receptor for cellular entry in swine PK-15 cells. | 42274214 |
| 2026-06-03 | Experimental Infection Host Range Experiment | Mouse inoculation experiments demonstrated that the swine-origin A(H1N2) virus strain (A) caused marked clinical signs and mortality, while the turkey-adapted strain (B) and swine reference strain (C) produced weaker responses. | 42237404 |
| 2026-06-03 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analyses of A(H1N2) influenza virus sequences identified a turkey strain derived from a recent spillover from swine, a turkey-adapted strain, and a swine reference strain, indicating host-associated evolutionary divergence. | 42237404 |
| 2026-06-03 | Transmission Evidence Cross-species Transmission | A swine-origin A(H1N2) influenza virus emerged in pigs in France and subsequently spilled over into breeding turkey farms, causing a zoonotic infection. | 42237404 |
| 2026-06 | Zoonotic Surveillance Serological Evidence | Influenza A(H1N1)pdm09 antibodies were detected in unvaccinated swine across Norwegian counties during 2009/2010–2022/2023, indicating serological exposure. | 41857313 |
| 2026-06 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis showed that PRRSV2 sequences from meadow voles clustered within the PRRSV2 clade together with sequences from wild and domestic pigs, indicating close evolutionary relatedness among hosts. | 41684459 |
| 2026-06 | Zoonotic Surveillance Reservoir Ecology | Swine are identified as potential epidemiological bridges and reservoirs supporting the emergence and circulation of novel zoonotic influenza A viruses with pandemic potential. | 41857313 |
| 2026-06 | Zoonotic Surveillance Serological Evidence | Temporal correlation of influenza A(H1N1)pdm09 antibody prevalence between humans and swine in Norway suggests possible bidirectional spillover at the swine–human interface. | 41857313 |
| 2026-05-25 | Zoonotic Surveillance Reservoir Ecology | Shared influenza A virus genotypes were detected across white pigs, Iberian pigs, and wild boar in Toledo and Badajoz, indicating ecological circulation among swine populations. | 42244724 |
| 2026-05-25 | Zoonotic Surveillance Viral Detection | Influenza A virus genomes were detected and sequenced from Iberian and white pigs sampled across 24 provinces in Spain between 2019 and 2022. | 42244724 |

| 2026-05 | Zoonotic Surveillance Viral Detection | Recombinant H5 antigen was detected by ELISA in wild boar sera from Spanish areas overlapping with H5N1 HPAI outbreaks, although H5N1 HI assays were negative. | 41668256 |
| 2026-05 | Zoonotic Surveillance Viral Detection | Potential spillover of Influenza A viruses from humans or other animal sources to wild boars in Spain was inferred from surveillance data. | 41668256 |
