Abstract
The Thiverval vaccine strain of classical swine fever virus (CSFV) was derived from virulent Alfort strain through the serial passages in cells at 29–30°C. In this study, we determined the complete genome sequence of this strain and found that its genome contains one open reading frame (ORF) that encodes a polyprotein with 3,898 amino acids. The 5′-UTR of Thiverval is 373 nt long with only one mutation at position 220. In contrast, the length of 3′-UTR is highly heterogeneous ranging from 233 to 259 bp. The heterogeneity of length of the 3′-UTR was due to an insertion of a variable length of T-rich sequence ranging from 6 to 32 nt. The insertion may change the structure and free energy of the 3′-UTR, resulting in a destabilization of the 3′-UTR. Sequence alignment of Thiverval and other CSFV strains showed 85.2–99.6% identities at the nucleotide level and 92.5–99.5% at the amino acid level. The phylogenetic tree analysis of the complete ORF, partial region of E2, and NS5B suggests that the CSFV Thiverval strain belongs to genetic group 1 and subgroup 1.1. The results from this study provide insight into the molecular mechanism of the attenuation of Thiverval vaccine strain.
