title: Isolation and molecular characterization of a porcine teschovirus 1 isolate from China.
abstract: Porcine teschovirus 1 (PTV-1) (Swine/CH/IMH/03) was isolated from piglets in a farm in Inner Mongolia Province, P.R. China. It was confirmed by electron microscopy, RT-PCR, and sequencing. Comparison of the sequences of the amino acid and nucleotides and phylogenetic analysis of the polyprotein showed that PTV Swine/CH/IMH/03 strain is PTV-1. The isolated virus has closest relationship with Talfan strain, they shared 98.9% and 99.5% homology of amino acids and nucleotides, respectively, in the ORF of polyprotein. To our knowledge, this is the first report about isolation and identification of a PTV in China.
