T. Stadejek et al., COMPARATIVE SEQUENCE-ANALYSIS OF THE 5'-NONCODING REGION OF CLASSICALSWINE FEVER VIRUS-STRAINS FROM EUROPE, ASIA, AND AMERICA, Archives of virology, 141(3-4), 1996, pp. 771-777
Polymerase chain reaction was utilized to determine the sequence of a
280 base pair fragment from cDNAs of the 5' noncoding region of 29 iso
lates of classical swine fever virus. Phylogenetic analysis of the seq
uences revealed low level genomic variation that correlated with the g
eographic origins of the isolates.
