Emergence of a novel recombinant USA/GBI29/2015-like strain of Seneca Valley virus in Guangdong Province, 2018
2021
Since June 2017, several outbreaks of a Seneca Valley virus (SVV) USA/GBI29/2015-like strain have emerged in pigs in China. In our study, we successfully isolated the SVV strain CH-GDZQ-2018, confirmed by immunofluorescence and Western blot assays. Phylogenetic and recombinant analyses showed that the USA/GBI29/2015-like CH-GDZQ-2018 strain was the result of recombination between epidemic strains local to Guangdong, showing that SVV has undergone evolution in China.
