Figure 2

Ranges of pairwise evolutionary distances among CSFV genotypes, subgenotypes and isolates shown for different genomic regions. Bars represent minimum and maximum values of genetic distances of the entire 5´NTR-E2 region (3508–3510 nt), the full-length E2 encoding sequence (1119 nt), the E2 fragment (190 nt), and the 5´NTR fragment (150 nt). Genetic distances are shown on isolate level (white bars), on subgenotype level (grey bars), and on genotype level (black bars). The analyzed subgenotypes or pairs of subgenotypes or genotypes are indicated by the numbers preceding the bars. With the exception of CSFV “strain 39” [GenBank: AF407339] and strain Great Britain/1964 “Congenital Tremor” [GenBank: JQ411575], which are not assigned to a defined genotype, all sequences shown in the phylogenetic trees of Figure 3 and Figure 4 are included in the analysis. Genetic distances between sequences were calculated by the Kimura-2 parameter method.
