This study evaluates gaseous ozone's effectiveness in decontaminating PRRSV and PEDV from truck cabin surfaces, finding inconsistent and limited viral titer reduction.

This paper introduces a dynamic classification system for PRRSV-2 genetic variants using clustering algorithms and demonstrates its effectiveness in tracking genetic diversity over time.

This study compares phylogenetic-based methods for fine-scale classification of PRRSV-2 ORF5 sequences, identifying robust approaches that improve resolution over RFLP-typing.
