title: New serotypes of porcine teschovirus identified in Shanghai, China.
abstract: Teschoviruses are widely endemic and commonly found in pig fecal samples. In this study, we collected fecal specimens from various pig herds and genotyped them based on the VP1 gene. Of 322 samples, 276 were positive, giving a PTV infectivity rate of 85.7 %. PTV4 was the most common serotype found in Shanghai, followed by PTV8 and PTV10. Interestingly, Some Shanghai strains belonging to a new PTV serotype were also isolated. In phylogenetic analysis, PTV SH8 did not correspond to any known serotype. PTV4 and PTV6 showed similar levels of sequence identity to PTV SH8. These data suggest that PTV SH8 is a new serotype, distinct from the new serotype PTV wild boar/WB2C-TV/2011/HUN, which clusters with PTV SH2, SH10, and SH25.
