Reassessment of PRRSV-2 ORF5 sequences assigned to Lineage 4 in Japan identifies a previously unrecognized candidate lineage-level clade

2026-04-06

Abstract excerpt

<title>Abstract</title> <p>Porcine reproductive and respiratory syndrome virus type 2 (PRRSV-2) exhibits extensive genetic diversity, and ORF5-based classification provides a standardized framework for global molecular surveillance. In a previous nationwide study in Japan, lineage 4 (L4) was identified as a dominant lineage exhibiting unexpectedly high genetic diversity. This observation motivated a focused reass...
