Molecular characterization of the emergent PEDV strains. a Alignment of partial S protein sequences of 7 S-INDEL like strains in this study and the prototype S-INDEL strains in the United States (OH851 and Minnesota58), South Korea (KNU-1406-1), and China (ZL29). b Locations of unique amino acid (aa) insertions identified in the 91 detected sequences. The symbol “-” indicates an aa deletion. Unique variations of aa are labelled with yellow
