a, phylogenetic tree analysis of polyprotein for different porcine sapalovirus strains identified in Europe (UK) and Asia (South Korea, China), and US. Phylogenetic analysis based on whole genome sequences revealed that global PSV-1 formed two clusters, and the USA/IA33375/2015 strain together with Korean and Chinese strains formed a separate cluster from UK PSV-1 V13 strain. b, porcine sapalovirus alignment (aa position 887–927 of polyprotein with PSV/US/IA33375/2015 as reference) demonstrating insertions and deletions among different strains
