* The nucleotide sequences obtained in this study (bold sequences) were compared to those of other African swine fever virus (ASFV) strains representing each IGR genotype. Of the 56 ASFV sequences, 54 sequences, excluding the 19S3965 and 19S5464 isolates, were represented by the pre-existing Korea/19S804/wb/2019 isolate (marked with asterisk), showing 100% identity. The 10-bp STR unit (5′-GGAATATATA-3′) is underlined.

Figure 1. Global (A) and locality (B) maps showing the collection sites of African swine fever virus from wild boars in South Korea from October 2 to December 30, 2019. Local area in Paju county where the IGR variants and pre-existing strain were isolated (dotted box in panel A) are magnified in panel B. Dot marked with an arrow in the inset map of panel A indicates the place where the first African swine fever case was detected in a wild boar in South Korea. The collection sites of IGR variants I, II, and III in Paju county are indicated by a triangle, dot, and square, respectively, in panel B.
Figure 2. Phylogenetic analyses of partial B646L (A) andEP402R (B) sequences of African swine fever virus isolates obtained in this study. The neighbour-joining trees were constructed with MEGA 6 based on the Kimura 2-parameter model. Numerals on branching nodes indicate the bootstrap values obtained with 1,000 replicates (>50%). The sequences obtained in this study are distinguished by bold letters, while the phylogenetic positions of 54 sequences other than those of 19S3965 and 19S5464 isolates are represented by that of the pre-existing Korea/19S804/wb/2019 isolate (marked with asterisk).
