Identification of Group A Porcine Rotavirus Strains Bearing a Novel VP4 (P) Genotype in Italian Swine Herds

摘要

The VP4 gene of a G5 Italian porcine rotavirus strain, 344/04-1, was nontypeable by PCR genotyping. The amino acid sequence of the full-length VP4 protein had low identity (≤76.6%) with the homologous sequences of representative strains of the remaining P genotypes, providing evidence for a novel P genotype.
