Fig. 2From: The emergence of porcine epidemic diarrhoea in Croatia: molecular characterization and serologyPhylogenetic relationship between the Croatian PEDV strain detected in 2016 and the selected reference strains (S gene segment-based). The phylogenetic tree was constructed from an almost complete PEDV S gene and a partial ORF 3 gene (4,173 nt in total) using a neighbour-joining method and the MEGA7 software with p-distances and 1000 bootstrap replicates (indicated adjacent to the nodes when > 70%). The first Croatian PEDV strain (CRO/OB-15343/2016) is tagged with a red rhombus. The GenBank accession numbers for the selected PEDV reference strains are designated within taxa.
