2026-06 Zoonotic Surveillance Aggregated samples from swine and cattle environments revealed diverse animal and zoonotic viruses, demonstrating the effectiveness of livestock-based environmental sampling for zoonotic surveillance. 41695450
2026-04-16 Zoonotic Surveillance HEV RNA was detected in wild boars in Portugal, with one full genome identified as genotype 3m, representing molecular surveillance of zoonotic HEV in wildlife. 42075757
2026-04-16 Genomic Evolution Full-genome sequencing and phylogenetic analysis showed that Hepatitis E virus from wild boars in Portugal belongs to genotype 3m and is closely related to human-derived strains from Spain and France. 42075757
2026-04-16 Reservoir Ecology Wild boars in Portugal were found to maintain Hepatitis E virus genotype 3m, confirming their role as a natural reservoir and indicating cross-border viral movement from Spain. 42075757
2026-04-16 Genomic Evolution Phylogenetic comparison using partial genome fragments indicated co-circulation of HEV subtypes 3e, 3f, and 3m among domestic pigs and wild boars in Portugal. 42075757
2026-04-16 Genomic Evolution Phylogeographic analysis indicated that the wild boar HEV-3m strain from Portugal likely originated from Spain, consistent with cross-border transmission. 42075757
2026-04-16 Cross Species Transmission HEV-3m strains found in Portuguese wild boars likely originated from Spanish wild boars, demonstrating cross-border animal-to-animal transmission. 42075757
