Molecular Characterization of African Swine Fever Virus, China, 2018

Abstract

On August 3, 2018, an outbreak of African swine fever in pigs was reported in China. We subjected a virus from an African swine fever–positive pig sample to phylogenetic analysis. This analysis showed that the causative strain belonged to the p72 genotype II and CD2v serogroup 8.

Outbreak of African swine fever in South Korea, 2019

“…Also, this strain has the characteristic of the intergenic region (IGR) II variant of genotype II group, which has an additional tandem repeat sequence (5'‐GGAATATATA‐3') between the I73R and I329L. The IGR II variant is identical to those observed in Ukr12/Zapo, Lt14/1490, Pol14/Krus (Gallardo et al, ), and China strains (SY18 and CN201801) (Ge et al, ). We compared the nucleotide sequences of p72 and p54 of Korea/Pig/Paju1/2019 with those of Georgia 2007/1, SY18/China/2018, AnhuiXCGQ/China/2018 and VNUA/HY/Vietnam (GenBank accession nos.…”

Infection of African swine fever in wild boar, China, 2018

“…After its spread from eastern Africa to Georgia in 2007, ASF has become more prevalent in the Caucasus region, further spread in Russian Federation, and then progressively affected the eastern Europe, including Ukraine (2012), Belarus (2013), Lithuania (2014), Estonia (2014), Poland (2014), Latvia (2014), Romania (2017), the Czech Republic (2017) and Hungary (2018). In 2018, ASF spread into China (Ge et al., ) and Belgium (Linden et al., ).…”

Re‐emergence of genotype I of African swine fever virus in Ivory Coast

“…More recently, in July 2018, an outbreak of ASF was reported for the first time in China and is still ongoing. The molecular characterization of outbreak samples showed that isolates belong to genotype II (Ge et al., ). Similarly, in September 2018, Belgium reported ASF in two wild boars near the village of Etalle in the province of Luxembourg caused by isolates belonging to genotype II (Garigliany et al., ).…”
