Identification of a Novel Porcine Teschovirus Subtype 19 within the Species Teschovirus A

Figure 1

Evolutionary PTV relationships based on the amino acid sequences of the VP1 (a), P1 (b), polyprotein (c), and 3 CD (d) genes. The evolutionary history was inferred using the maximum-likelihood in the Jones–Taylor–Thornton model with gamma-distributed rates and proportions of invariant sites (G + I) in MEGA 6.06 software. The percentages of the replicates in which the associated virus clustered together in the bootstrap test (1,000 replicates) are shown next to the branches (only values >70% are shown) in each tree. There were 272, 878, 2,225, and 657 positions in the VP1, P1, polyprotein, and 3 CD datasets, respectively. The strains isolated in the present study are indicated by squares. The novel genotype isolate (PTV 19-SG2) is indicated by triangles.
