| 2026-07-18 | Experimental Infection Host Range Experiment | Intramammary exposure to bovine-derived H5N1 causes productive infection in lactating sows despite prior vaccination. | 42523357 |
| 2026-07-10 | Zoonotic Surveillance Viral Detection | HPAI H5N1 was identified in a Wisconsin dairy herd in December 2025 through the National Milk Testing Strategy. | 42429628 |
| 2026-07-06 | Experimental Infection Host Range Experiment | Bovine H5N1 (HPAI 2.3.4.4b genotype B3.13) replicates efficiently in porcine mammary gland and respiratory tract cells. | 42405777 |
| 2026-07-02 | Zoonotic Surveillance Reservoir Ecology | Naturally infected cattle shed HPAIV H5N1 extensively in milk, indicating the bovine mammary gland as a site of viral replication relevant to circulation in dairy herds. | 42390302 |
| 2026-06 | Zoonotic Surveillance Reservoir Ecology | Highly pathogenic avian influenza virus (HPAIV) H5N1 clade 2.3.4.4b spilled over from wild birds to dairy cattle in the United States, affecting more than 1000 herds. | 41819722 |
| 2026-06 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis showed that BVDV‑1a sequences from small ruminants in Türkiye clustered closely with Turkish cattle strains, indicating evolutionary relatedness between bovine and ovine viruses. | 41917271 |
| 2026-06 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis revealed BVDV‑1a from sheep to be closely related to Turkish cattle strains, indicating cross‑species transmission between cattle and sheep. | 41917271 |
| 2026-06 | Zoonotic Surveillance Reservoir Ecology | A quantitative model predicted potential spillover introductions of HPAIV H5N1 from wild birds to cattle in Denmark, with estimated rates below 0.35 cases per week. | 41819722 |
| 2026-05-24 | Experimental Infection Pathogenicity Experiment | High-dose intramammary inoculation of influenza A(H5N1) caused severe disease and mortality in experimentally infected dairy cows. | 42177170 |
| 2026-05-17 | Zoonotic Surveillance Serological Evidence | BVDV-specific antibodies were detected in 15.9% of cattle serum samples from mixed herds in southern Bangladesh. | 42161068 |
| 2026-05-17 | Zoonotic Surveillance Viral Detection | Genetically related BVDV-1, BVDV-2, and HoBi-like viruses were detected in both cattle and water buffalo within mixed herds in southern Bangladesh, indicating cross-species transmission and co-circulation between these bovine hosts. | 42161068 |
| 2026-05-17 | Zoonotic Surveillance Viral Detection | BVDV-1 RNA was detected by RT-qPCR in blood samples from cattle and water-buffalo in mixed herds in the southern region of Bangladesh, and 5'-UTR sequencing identified multiple BVDV-1 subgenotypes. | 42161068 |
| 2026-05-17 | Genomic Evolution Phylogenetic Evolution | Phylogenetic analysis of 5'-UTR sequences revealed eight BVDV-1 subgenotypes co-circulating in cattle and water buffalo in Bangladesh with high nucleotide identity. | 42161068 |
| 2026-05-17 | Zoonotic Surveillance Virus Isolation | Bovine viral diarrhea virus (BVDV) was isolated from cattle and water-buffalo samples using the MDBK cell line, with cytopathic and non-cytopathic biotypes identified. | 42161068 |
