- Sequences of 5′-UTR and E2 regions were analyzed (N, number of sequences). Pairwise distances were estimated separately for two groups of sequences (reference genotypes and samples) with the use of the Tamura-Nei model. Means of distances within each group are given with corresponding standard deviations (S.D.). Differences between the means (bold) for references and isolates are significant at the p < 0.001 level (Student’s t-test)
