* 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).
