Phylogenetic analyses of large numbers of classical swine fever strains have revealed a high degree of sequence conservation in the genomic regions examined, suggesting either a recent common ancestor or a low evolution rate. This low variability is in contrast to findings with other RNA viruses. To investigate the consequence of this apparent genetic stability on phylogenetic examinations, the Belgian field isolate Wingene’93 was passaged in pigs as well as in cell culture by various methods. Sequence analyses of viruses collected after various passages in three target regions proposed for…
