Nucleotide sequence of the cDNA for porcine rotavirus VP7 gene (strain K).

The nucleotide sequence of the cDNA encoding one of the neutralizing proteins VP7 of the new porcine strain K is determined. The deduced VP7 amino acid sequence of the K strain showed a high homology (93%) and a lower homology (75%) to those of the Gottfried and OSU strains, respectively. This finding suggests that strain K is more closely related to the Gottfried strain serotype 4.
