Abstract

Porcine teschovirus (PTV) comprises at least 13 genotypes (PTV 1–13). Here, the genotypes of field strains prevalent among pig populations in Hunan Province, China, were identified. Multiple PTV genotypes, including all genotypes except PTV 7 and 8, were found co-circulating in the pig populations, reflecting a high genetic diversity. Moreover, we identified nine novel PTV genotypes, provisionally designated as PTV 14–22. PTV 21-HuN41 and PTV 21-HuN42 were successfully isolated, and their nearly complete genomes were sequenced. Homology comparison of the polyprotein genes of PTV 21-HuN41–42 to those of other known PTVs revealed low identities, ranging from 70.1 to 71.9 % (nucleotide identity) and 75.4 to 77.6 % (amino acid identity). Moreover, PTV 21-HuN41–42 were identified as a novel teschovirus species (tentatively Teschovirus B), based on the analyses of phylogenetics and evolutionary divergence. The findings of this study are expected to greatly enrich our knowledge of PTV genotypes.
