Deduced amino acid analysis of PEDV variants
To elucidate the genetic characteristics of S-INDEL like strains detected in this study, partial S gene sequences were aligned with reference S-indel strains from US (OH851), South Korea (KNU-1406-1), and China (ZL29) using MEGA 6.0 software. The novel mutation, insertion, and deletion in S proteins were also detected in this study.
