COMPARISON OF THE ENTIRE NUCLEOTIDE AND DEDUCED AMINO-ACID-SEQUENCES OF THE ATTENUATED HOG-CHOLERA VACCINE STRAIN GPE- AND THE WILD-TYPE PARENTAL STRAIN ALD

We have determined the complete nucleotide sequences of a live attenuated hog cholera virus (HCV) and its progenitor strain. The viral RNA of each strain consisted of 12298 nucleotides including untranslated regions of 373 and 228 bases at the 5' and 3' end, respectively. There was a single large open reading frame spanning 11697 nucleotides which could encode a large protein of 3899 amino acids with a calculated molecular weight of 438-kDa. We have found 225 nucleotide difference between the two strains, of which six were located in the untranslated region. Four-sixths of these differences resulted in amino acid substitutions.
