Figure 1From: Comparative analysis of complete nucleotide sequence of porcine reproductive and respiratory syndrome virus (PRRSV) isolates in Thailand (US and EU genotypes)Phylogenetic relationship of PRRS viruses, full length genome Sequences. Whole genome sequences of ORF1-ORF7 were used for phylogenetic analysis using PAUP program applying NJ algorithm with distance setting of total character difference. Bootstrap analysis was conducted with 1000 replication.Back to article page
