The primary nucleotide sequence of the fragment of E1 (gp51-55) gene (772 bp in length) of virulent strain Shi-Min’ of classical swine fever virus (CSFV) has been determined. Multiple alignments of the E1 gene fragments of various strains and isolates of CSFV, which are homologues to the cloned fragment, has been carried out; the phylogenetic tree has been plotted and the consensus sequence has been determined. The strain Shi-Min’, which was used as a control CSFV strain in former Soviet republics, and the referent strain Alfort were shown to be located on the opposite sides of the dendrogram, while Shi-Min’ was more close to the western European group of CSFVs. We suggest that Shi-Min’ strain as a positive viral antigen for vaccine testing represents a selective factor for the formation of virus population in Ukraine. The data obtained are the first results in molecular epizootic study of hog cholera in Ukraine.
