Abstract
Senecavirus A (SVA) belongs to the genus Senecavirus in the family Picornaviridae. This virus possesses a positive-sense, single-stranded RNA genome, approximately 7200 nt in length, composed of a single 5' untranslated region, encoding region and 3' untranslated region. In this study, a recombinant SVA tagged with enhanced green fluorescent protein (eGFP) sequence, rSVA-eGFP, was rescued from its cDNA clone using reverse genetics. The passage-5 (P5) rSVA-eGFP was totally subjected to 55 rounds of consecutive fluorescent plaque-to-fluorescent plaque (FP-FP) transfers, and one extra common passaging in vitro. The P61 viral stock was analyzed by next-generation sequencing. The result showed ten single-nucleotide mutations (SNMs) in the rSVA-eGFP genome, including nine transitions and only one transversion. The P61 progeny still showed a complete eGFP sequence, indicating no occurrence of copy-choice recombination within the eGFP region during serial FP-FP transfers. In other words, this progeny was genetically deficient in the recombination of eGFP sequence (RES), namely, an RES-deficient strain. Out of ten SNMs, three were missense mutations, leading to single-amino acid mutations (SAAMs): F15V in L protein, A74T in VP2, and E53R in 3D protein. The E53R was predicted to be spatially adjacent to the RNA channel of 3D protein, perhaps involved in the emergence of RES-deficient strain. In conclusion, this study uncovered a global landscape of rSVA-eGFP genome after serial FP-FP transfers, and moreover shed light on a putative SAAM possibly related to the RES-deficient mechanism.

Abstract
Porcine idiopathic vesicular disease (PIVD), one of several clinically indistinguishable vesicular diseases of pigs, is caused by the emerging pathogen Senecavirus A (SVA). Despite the widespread prevalence of porcine SVA infection, no effective commercial vaccines for PIVD prevention and control are available, due to high costs associated with vaccine testing in pigs, considerable SVA diversity, and SVA rapid evolution. In this study, SVA CH/JL/2022 (OP562896), a novel mutant SVA strain derived from an isolate obtained from a pig farm in Jilin Province, China, was inactivated then combined with four adjuvants, MONTANIDETM GEL02 PR (GEL 02), MONTANIDETM ISA 201 VG (ISA 201), MONTANIDETM IMG 1313 VG N (IMS1313), or Rehydragel LV (LV). The resulting inactivated SVA CH/JL/2022 vaccines were assessed for efficacy in mice and found to induce robust in vivo lymphocyte proliferation responses and strong IgG1, IgG2a, and neutralizing antibody responses with IgG2a/IgG1 ratios of <1. Furthermore, all vaccinated groups exhibited significantly higher levels of serum cytokines IL-2, IL-4, IL-6, and IFN as compared to unvaccinated mice. These results indicate that all vaccines elicited both Th1 and Th2 responses, with Th2 responses predominating. Moreover, vaccinated mice exhibited enhanced resistance to SVA infection, as evidenced by reduced viral RNA levels and SVA infection-induced histopathological changes. Collectively, our results demonstrate that the SVA-GEL vaccine induced more robust immunological responses in mice than did the other three vaccines, thus highlighting the potential of SVA-GEL to serve an effective tool for preventing and controlling SVA infection.

Abstract
IMPORTANCE Senecavirus A (SVA) is an emerging picornavirus associated with vesicular disease, which wide spreads around the world. It has evolved multiple strategies to evade host immune surveillance. The mechanism and pathogenesis of the virus infection remain unclear. In this study, we show that SERPINB1, a member of the SERPINB family, promotes SVA replication, and regulates both innate immunity and the autophagy pathway. SERPINB1 catalyzes K48-linked polyubiquitination of IκB kinase epsilon (IKBKE) and degrades IKBKE through the proteasome pathway. Inhibition of IKBKE expression by SERPINB1 induces autophagy to decrease type I interferon signaling, and ultimately promotes SVA proliferation. These results provide importantly the theoretical basis of SVA replication and pathogenesis. SERPINB1 could be a potential therapeutic target for the control of viral infection.

Abstract
Senecavirus A (SVA) can cause a vesicular disease in swine. It is a positive-strand RNA virus belonging to the genus Senecavirus in the family Picornaviridae. Positive-strand RNA viruses possess positive-sense, single-stranded genomes whose untranslated regions (UTRs) have been reported to contain cis-acting RNA elements. In the present study, a total of 100 SVA isolates were comparatively analyzed at the genome level. A highly conserved fragment (HCF) was found to be located in the 3D sequence and to be close to the 3' UTR. The HCF was computationally predicted to form a stem-loop structure. Eight synonymous mutations can individually disrupt the formation of a single base pair within the stem region. We found that SVA itself was able to tolerate each of these mutations alone, as evidenced by the ability to rescue all eight single-site mutants from their individual cDNA clones, and all of them were genetically stable during serial passaging. However, the replication-competent SVA could not be rescued from another cDNA clone containing all eight mutations. The failure to recover SVA might be attributed to disruption of the predicted stem-loop structure, whereas introduction of a wild-type HCF into the cDNA clone with eight mutations still had no effect on virus recovery. These results suggest that the putative stem-loop structure at the 3' end of the 3D sequence is a cis-acting RNA element that is required for SVA growth.

A putative wild-type or wild-type-like hairpin structure is required within 3' untranslated region of Senecavirus A for virus replication. Virology 2023; 585:72-77.

Abstract
The 3' untranslated region (UTR) of Senecavirus A (SVA) was predicted to harbor two hairpin structures, hairpin-I and -II. The former is composed of two internal loops, one terminal loop and three stem regions; the latter comprises one internal loop, one terminal loop and two stem regions. In this study, we constructed a total of nine SVA cDNA clones, which contained different point mutations within a stem-formed motif in the hairpin-I or -II, for rescuing replication-competent viruses. Only three mutants were successfully rescued and moreover genetically stable during at least five serial passages. Computer-aided prediction showed these three mutants bearing either a wild-type or a wild-type-like hairpin-I in their individual 3' UTRs. Neither wild-type nor wild-type-like hairpin-I could be computationally predicted to exist in 3' UTRs of the other six unviable "viruses". The results suggested that the wild-type or wild-type-like hairpin-I was necessary in the 3' UTR for SVA replication.

Abstract
Senecavirus A (SVA) is an emerging pathogen that negatively affects the pig industry in China. Affected animals present vesicular lesions which are indistinguishable from other vesicular diseases. To date, there is no commercial vaccine that can be used to control SVA infection in China. In this study, recombinant SVA 3AB, 2C, 3C, 3D, L and VP1 proteins are expressed by using a prokaryotic expression system. The kinetics of the presence and levels of SVA antibodies with SVA-inoculated pig serum show that 3AB has the best antigenicity. An indirect enzyme-linked immunosorbent assay (ELISA) is developed with the 3AB protein, exhibiting a sensitivity of 91.3% and no cross-reaction with serum antibodies against PRRSV, CSFV, PRV, PCV2 or O-type FMDV. Given the high sensitivity and specificity of this approach, a nine-year (2014–2022) retrospective and prospective serological study is conducted to determine the epidemiological profile and dynamics of SVA in East China. Although SVA seropositivity declined markedly from 2016 (98.85%) to 2022 (62.40%), SVA transmission continues in China. Consequently, the SVA 3AB-based indirect ELISA has good sensitivity and specificity and is suitable for viral detection, field surveillance and epidemiological studies.

Abstract
Picornavirus possesses one positive-sense, single-stranded RNA genome, in which a cis-acting replication element (cre) is located. The cre is a stem-loop structure that harbors a conserved AAACA motif within its loop region. This motif functions as a template for adding two U residues to the viral VPg, therefore generating a VPg-pUpU that is required for viral RNA synthesis. Senecavirus A (SVA) is an emerging picornavirus. Its cre has not been identified as yet. In the present study, one putative cre containing a typical AAACA motif was computationally predicted to exist within the VP2-encoding sequence of SVA. To test the role of this putative cre, 22 SVA cDNA clones with different point mutations in their cre-formed sequences were constructed in an attempt to rescue replication-competent SVAs. A total of 11 viruses were rescued from their individual cDNA clones, implying that some mutated cres exerted lethal impacts on SVA replication. To eliminate these impacts, an intact cre was artificially inserted into those SVA cDNA clones without ability of recovering virus. The artificial cre was proven to be able of compensating for some, but not all, defects caused by mutated cres, leading to successful recovery of SVAs. These results indicated that the putative cre of SVA was functionally similar to those of other picornaviruses, perhaps involved in the uridylylation of VPg.

Abstract
Senecavirus A (SVA) is an emerging virus that belongs to the genus Senecavirus in the family Picornaviridae. Its genome is a positive-sense and single-stranded RNA, containing two untranslated regions (UTRs). The 68-nt-long 3′ UTR is computationally predicted to possess two higher-order RNA structures: a kissing-loop interaction and an H-type-like pseudoknot, both of which, however, cannot coexist in the 3′ UTR. In this study, we constructed 17 full-length SVA cDNA clones (cD-1 to -17): the cD-1 to -7 contained different point mutations in a kissing-loop-forming motif (KLFM); the cD-8 to -17 harbored one single or multiple point mutations in a pseudoknot-forming motif (PFM). These 17 mutated cDNA clones were independently transfected into BSR-T7/5 cells for rescuing recombinant SVAs (rSVAs), named rSVA-1 to −17, corresponding to cD-1 to −17. The results showed that the rSVA-1, -2, -3, -4, -5, -6, -7, -9, -13, and -15 were successfully rescued from their individual cDNA clones. Moreover, all mutated motifs were genetically stable during 10 viral passages in vitro. This study unveiled viral abilities of tolerating mutations in the computationally predicted KLFM or PFMs. It can be concluded that the putative kissing-loop structure, even if present in the 3′ UTR, is unnecessary for SVA replication. Alternatively, if the pseudoknot formation potentially occurs in the 3′ UTR, its deformation would have a lethal effect on SVA propagation.

Abstract
Senecavirus A (SVA), a newly emergent picornavirus correlated with sudden neonatal mortality and vesicular lesions in pigs, has had a considerable impact on the global pig farming industry. Timely and dependable detection of SVA is helpful in preventing the further spread of this pathogenic virus. In the current study, a real-time fluorescent reverse transcription recombinase-aided amplification (rRT-RAA) assay, which targets the most conserved region within the VP2 gene of SVA, was developed and evaluated for SVA detection. The detection limit for this assay was tested to be 1.185 50% tissue culture infective dose (TCID50 ) of SVA RNA per reaction at a 95% confidence interval, which is comparable to that of a previously published rRT-PCR assay for SVA. The testing results of the rRT-RAA assay were very reproducible and repeatable, with inter- and intra-assay coefficient of variation values less than 7.0%. In addition, the established rRT-RAA assay displayed excellent specificity for SVA detection without cross-reaction with other clinically important swine pathogenic viruses. The diagnostic performance of rRT-RAA was evaluated using 189 clinical swine samples, which were detected in parallel using the reference rRT-PCR assay. The results showed that 146 and 151 samples tested positive for SVA by rRT-RAA and rRT-PCR, respectively. The overall agreement between both assays was 97.4% (184/189) with a kappa value of 0.927 (p < .001). Further linear regression analysis demonstrated that the detection results between the two assays were significantly correlated (R2 = 0.9192, p < .0001). Taken together, our newly established rRT-RAA assay is a powerful and time-saving diagnostic tool for SVA detection in clinical samples. This article is protected by copyright. All rights reserved.

Pathogenicity of Seneca Valley virus in pigs and detection in Culicoides from an infected pig farm. Virol J 2021; 18:209. [PMID: 34674719 PMCID: PMC8529370 DOI: 10.1186/s12985-021-01679-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 10/08/2021] [Indexed: 02/07/2023] Open
Abstract
Background Porcine vesicular disease is caused by the Seneca Valley virus (SVV), it is a novel Picornaviridae, which is prevalent in several countries. However, the pathogenicity of SVV on 5–6 week old pigs and the transmission routes of SVV remain unknown. Methods This research mainly focuses on the pathogenicity of the CH-GX-01-2019 strain and the possible vector of SVV. In this study, 5–6 week old pigs infected with SVV (CH-GX-01-2019) and its clinical symptoms (including rectal temperatures and other clinical symptoms) were monitored, qRT-PCR were used to detect the viremia and virus distribution. Neutralization antibody assay was set up during this research. Mosquitoes and Culicoides were collected from pigsties after pigs challenge with SVV, and SVV detection within mosquitoes and Culicoides was done via RT-PCR. Results The challenged pigs presented with low fevers and mild lethargy on 5–8 days post infection. The viremia lasted more than 14 days. SVV was detected in almost all tissues on the 14th day following the challenge, and it was significantly higher in the hoofs (vesicles) and lymph nodes in comparison with other tissues. Neutralizing antibodies were also detected and could persist for more than 28 days, in addition neutralizing antibody titers ranged from 1:128 to 1:512. Mosquitoes and Culicoides were collected from the pigsty environments following SVV infection. Although SVV was not detected in the mosquitoes, it was present in the Culicoides, however SVV could not be isolated from the positive Culicoides. Conclusions Our work has enriched the knowledge relating to SVV pathogenicity and possible transmission routes, which may lay the foundation for further research into the prevention and control of this virus.

The Insufficient Activation of RIG-I-Like Signaling Pathway Contributes to Highly Efficient Replication of Porcine Picornaviruses in IBRS-2 Cells. Mol Cell Proteomics 2021; 20:100147. [PMID: 34530158 PMCID: PMC8503670 DOI: 10.1016/j.mcpro.2021.100147] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 09/04/2021] [Accepted: 09/10/2021] [Indexed: 12/22/2022] Open
Abstract
Seneca Valley virus (SVV) or commonly known as senecavirus A, is one of the picornavirus that is associated with vesicular disease and neonatal mortality in swine herds. Our previous study found that SVV replicates extremely faster in porcine Instituto Biologico-Rim Suino-2 (IBRS-2) cells than that in porcine kidney-15 (PK-15) cells. However, the underlying mechanism remains unknown. In this study, we comprehensively compared the expression features between IBRS-2 cells and PK-15 cells in response to SVV infection by an unbiased high-throughput quantitative proteomic analysis. We found that the innate immune response–related pathways were efficiently activated in PK-15 cells but not in IBRS-2 cells during SVV infection. A large amount of interferon (IFN)-stimulated genes were induced in PK-15 cells. In contrast, no IFN-stimulated genes were induced in IBRS-2 cells. Besides, we determined similar results in the two cell lines infected by another porcine picornavirus foot-and-mouth disease virus. Further study demonstrated that the Janus kinase signal transducer and activator of transcription signaling pathway was functioning properly in both IBRS-2 and PK-15 cells. A systematic screening study revealed that the aberrant signal transduction from TANK-binding kinase 1 to IFN regulatory factor 3 in the retinoic acid–inducible gene I–like receptor signaling pathway in IBRS-2 cells was the fundamental cause of the different innate immune response manifestation and different viral replication rate in the two cell lines. Together, our findings determined the different features of IBRS-2 and PK-15 cell lines, which will help for clarification of the pathogenesis of SVV. Besides, identification of the underlying mechanisms will provide new targets and an insight for decreasing the viral clearance rate and probably improve the oncolytic effect by SVV in cancer cells. Divergent innate immune responses were triggered by SVV in IBRS-2 and PK-15 cells. SVV induced higher levels of type I IFN in PK-15 cells than in IBRS-2 cells. IBRS-2 cell line has an aberrant RLR pathway but an intact type I IFN pathway. TBK1-mediated antiviral signal transduction was dysfunctional in IBRS-2 cells.

Isolation and evolutionary analysis of Senecavirus A isolates from Guangdong province, China. INFECTION GENETICS AND EVOLUTION 2021; 91:104819. [PMID: 33771724 DOI: 10.1016/j.meegid.2021.104819] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 03/09/2021] [Accepted: 03/22/2021] [Indexed: 02/05/2023]
Abstract
Senecavirus A (SVA), an emerging swine pathogen, has been reported in many provinces of China since the first outbreak in 2015 in Guangdong province. In this study, 10 lymph nodes positive for SVA, collected between 2018 and 2019 from slaughterhouses in Guangdong province, were subjected to virus isolation. Rapid and evident cytopathic effects (CPEs) were observed in SVA-infected PK-15 cells, including shrinking, rounding and detaching, with peak titers being reached at 24 h post infection (hpi). Electron microscopy showed that SVA particles are spherical and approximately 30 nm in diameter, and exist as crystalline lattices in cytoplasm revealed by ultra-thin sectioning. Phylogenetic analysis based on the whole genome sequences of all available isolates showed that SVA globally can be divided into two groups with each being further divided into two subgroups (Ia-b and IIa-b), and with the Guangdong isolates obtained here and other Chinese strains belonging to subgroups IIa and IIb. Evolutionary analysis showed that the mean substitution rate of SVA was 2.696 × 10-3 per site per year based on whole genomic sequences, with subgroup IIb isolates having evolved faster than those of subgroup IIa. Analysis of efficient population size showed that the outbreak point of SVA worldwide occurred at the end of 2013 with that of subgroup IIb, the current dominant group, in mid 2014.

[PMID: 33670589 PMCID: PMC7922346 DOI: 10.3390/life11020157] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 02/04/2021] [Accepted: 02/16/2021] [Indexed: 11/16/2022] Open
Abstract
Senecavirus A (SVA), formerly known as Seneca Valley virus (SVV), causes vesicular symptoms in adult pigs and acute death of neonatal piglets. This pathogen has emerged in major swine producing countries around the world and caused significant economic losses to the pig industry. Thus, it is necessary to develop strategies to prevent and control SVA infection. Herein, an SVA strain (named GD-ZYY02-2018) was isolated from a pig herd with vesicular symptoms in Guangdong province of China in 2018. The present study aimed to carry out the phylogenetic analysis of the GD-ZYY02-2018 strain, determine its pathogenicity in finishing pigs, and assess the protective efficacy of the inactivated GD-ZYY02-2018 strain against virus challenge. The results of phylogenetic analysis showed that the SVA GD-ZYY02-2018 strain belonged to the USA-like strains and had a close genetic relationship with recent Chinese SVA strains. Animal challenge experiment showed that 100-day-old pigs inoculated intranasally with SVA GD-ZYY02-2018 strain developed vesicular lesion, low fever, viremia, and virus shedding in feces. The immunization challenge experiment showed that pigs vaccinated with inactivated GD-ZYY02-2018 strain could produce a high titer of anti-SVA neutralizing antibody and no vesicular lesion, fever, viremia, and virus shedding in feces was observed in vaccinated pigs after challenge with GD-ZYY02-2018 strain, indicating that inactivated GD-ZYY02-2018 could protect finishing pigs against the challenge of homologous virus. In conclusion, preliminary results indicated that inactivated GD-ZYY02-2018 could be used as a candidate vaccine for in-depth research and might be conducive to the prevention and control of SVA infection.

Abstract
Seneca Valley virus (SVV) is a novel Picornaviridae that is closely associated with porcine idiopathic vesicular disease (PIVD). Here, a novel SVV strain (CH-GX-01-2019) was detected and isolated from swine in Guangxi Province, China. The complete genomic sequence of CH-GX-01-2019 exhibited 93.3-98.9 % identify with other SVV isolates at the nucleotide level. CH-GX-01-2019 showed the highest level of similarity (98.9 %) with Vietnamese strains. And CH-GX-01-2019 exhibited two consecutive amino acid mutations in VP1 gene. Phylogenetic analysis based on the complete genome and the VP1 gene showed that Chinese SVV isolates can be divided into three clusters. We analyzed the geographical distributions of SVV strains in China and found that the epidemiology of SVV in China is complicated; most strains are distributed predominantly in south and central China. Between 2015 and 2019, the dominant epidemic SVV isolates in China have changed from clusters 1 and 3 to cluster 2. CH-GX-01-2019 (cluster 3) is a recombinant strain from Colombia-2016 (cluster 2) and HB-CH-2016 (cluster 1). Our findings will enhance our understanding of the prevalence and genetic variation of SVV in the swine herds of China and provide important insights into the molecular epidemiology of SVV.

Abstract
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.
