Genetic and phylogenetic analysis of reemerged novel Seneca Valley virus strains in Guangdong province, 2017

Abstract: From June to July 2017, six Seneca Valley virus (SVV) strains were isolated from swine herds exhibiting SVV-associated porcine idiopathic vesicular disease (PIVD) in Guangdong province, China. Complete genomic sequences of these six newly identified strains were genetically and phylogenetically analysed. The results revealed that these six SVV strains were genetically closely related to USA/GBI29/2015 and notably distinct from all previous Chinese strains, indicating the reemergence of new SVV strains in Guang… Show more

“…From 2015 to 2016, SVV infection in pigs was reported in more regions in Brazil, the United States, China, Canada, Colombia, and Thailand with an extensive distribution ( Rademacher et al, 2015 ; Joshi et al, 2016a , b ; Leme et al, 2016a ; Saeng-Chuto et al, 2017 ; Sun et al, 2017 ; Wang et al, 2017 ). New cases of SVV were reported in the United States and China in 2017 ( Sturos, 2017 ; Zhang et al, 2017 ; Zhu et al, 2017 ; Liu et al, 2018 ), and the 2016 is considered as a turning point for the SVV epidemiology in China. Two different subclades have been identified.…”

“…Immunohistochemical (IHC) staining and in situ hybridization are also established methods to identify SVV antigen and RNA in tissue samples ( Joshi et al, 2016a ; Leme et al, 2016a ; Resende et al, 2017 ). SVV RNA can be detected from the ruptured snout, necrotizing lesions in the tongue and skin of the coronary band of infected adult pigs ( Resende et al, 2017 ; Zhu et al, 2017 ; Liu et al, 2018 ), and pulmonary, myocardial and tonsilar tissues are the most important biological samples in which the virus can be detected in piglets ( Leme et al, 2016b ; Dall Agnol et al, 2017 ). A specific SVV monoclonal antibody was developed by Yang et al (2012) for serodiagnosis, and a competitive enzyme-linked immunosorbent assay (cELISA) was established using this antibody ( Yang et al, 2012 ).…”

“…The second group isolated six strains, and revealed nucleotide identities among their genomes ranging from 99.6 to 99.8%. These six strains shared the highest genomic identity with the USA/GBI29/2015 (98.5–98.6%), and were notably distinct from earlier isolates from China ( 36 ).…”

“…Since then, increasing cases of SVA infection have been reported in other provinces, including Heilongjiang, Hubei, Henan, Fujian, Hebei, and Anhui etc. (13)(14)(15)(16)(17)(18). However, the genomic information is still very limited in these regions except Guangdong province which account for over 70% of Chinese isolates (19).…”
