title: Comparative sequence analysis of the 5' noncoding region of classical swine fever virus strains from Europe, Asia, and America.
abstract: Polymerase chain reaction was utilized to determine the sequence of a 280 base pair fragment from cDNAs of the 5' noncoding region of 29 isolates of classical swine fever virus. Phylogenetic analysis of the sequences revealed low level genomic variation that correlated with the geographic origins of the isolates.
