Figure Legends
Fig 1. Time-mortality dynamic curve. The X axis shows time, and the Y axis shows the number of died pigs. The arrow is the time for the farm to inject its own inactivated vaccine.
Fig 2. Phylogenetic trees of isolates and a representative virus based on the S gene sequence. the tree was performed by neighbor-joining method using MEGA with 1,000 bootstrap replicates. The names of GenBank accession numbers, the strains, years, and places of isolation are show on the right in order, and the genogroups of virus are shown on the right of strains.
Supplementary Fig 1. Percentages of nucleotide identity among 26 PEDV isolates based on S gene sequence.
