“…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 ).…”

Review of Seneca Valley Virus: A Call for Increased Surveillance and Research

et al. 2018

View full text Add to dashboard Cite

Seneca Valley virus (SVV) has recently caused many vesicular diseases in pigs in different regions and countries. As a newly causative agent of porcine vesicular disease, SVV has evolved and spread quickly. It causes clinical signs similar to those of foot-and-mouth disease and results in significant economic losses. An increasing number of SVV outbreaks were reported in 2016 and 2017 in Brazil, United States, and China. However, few diagnostic methods have been established and no commercial vaccine has been available until now. Therefore, more attention needs to be paid to SVV, and urgent surveillance should be performed to prevent the spread of this virus. Although recent research has shed some light on SVV, there are still many aspects of the virus and the disease that are not yet fully understood, and many questions need to be resolved. This review presents current knowledge concerning SVV infection, epidemiology, pathogenicity, immune response, and diagnostic methods. This information will aid the design and adoption of effective prevention and control strategies to counter this viral pathogen.

“…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 ).…”

A 5-Year Review of Senecavirus A in China since Its Emergence in 2015

Senecavirus A (SVA), previously known as Seneca Valley virus, is classified into the genus Senecavirus in the family Picornaviridae . This virus can cause vesicular disease and epidemic transient neonatal losses in swine. Typical clinical signs include vesicular and/or ulcerative lesions on the snout, oral mucosa, coronary bands and hooves. SVA emerged in Guangdong Province of China in 2015, and thereafter gradually spread into other provinces, autonomous regions and municipalities (P.A.M.s). Nowadays more than half of the P.A.M.s have been affected by SVA, and asymptomatic infection has occurred in some areas. The phylogenetic analysis shows that China isolates are clustered into five genetic branches, implying a fast evolutionary speed since SVA emergence in 2015. This review presented current knowledge concerning SVA infection in China, including its history, epidemiology, evolutionary characteristics, diagnostics and vaccines.

“…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).…”

Senecavirus A (SVA), an emerging swine picornavirus of swine, is one of the causative agents of vesicular disease which is clinically indistinguishable from foot-and-mouth disease in pigs. Here, 3 cases of vesicular disease were reported which was caused by SVA in November 2018 in Henan, China. Three new SVA strains were identified and conducted a genetically evolutionary analysis. The isolates shared 98.1-99.0% genomic pairwise identity to each other and had the highest similarity, of 98.3-98.7%, with the American strain KS15-01, respectively. Phylogenetic analysis indicated that the Chinese prevalent strains could be clearly divided into cluster 1, cluster 2, and cluster 3. Furthermore, one isolate (HeNNY-1/2018) and two previously reported strains (HB-CH-2016 and SVA/CHN/10/2017) were identified as recombinants using several algorithms. It revealed that the recombination among SVA strains has occurred in China since 2016 or earlier. The findings of studies updated the prevalent status of SVA in China. Besides, the genetic evolution and recombinant events of SVA should be attracted more attentions in the future.
