Abstract
Lumpy skin disease virus (LSDV) is a rapidly emerging pathogen in China. Screening suitable cells for LSDV replication is vital for future research on pathogenic mechanisms and vaccine development. Previous comparative studies have identified that the rodent-derived BHK21 is a highly susceptible cell model to LSDV infection. Using western blot, indirect immune-fluorescence assay, flow cytometry, and transmission electron microscopy methods, this study is the first to identify the murine osteoblastic cell line MC3T3-E1 as a novel permissive cell model for LSDV infection. The establishment of MC3T3-E1 as a suitable infectious cell model enhances our understanding of the species range and cell types of the permissive cells and nonpermissive that support LSDV replication. It is helpful to accelerate future research on the pathogenesis, clinical application, and vaccine development of LSDV.

Abstract
Lumpy skin disease virus (LSDV) is a poxvirus that mainly affects cattle and can lead to symptoms such as severe reduction in milk production as well as infertility and mortality, which has resulted in dramatic economic loss in affected countries in Africa, Europe, and Asia. In this study, we successfully isolated two strains of LSDV from different geographical regions in China. Comparative genomic analyses were performed by incorporating additional LSDV whole genome sequences reported in other areas of Asia. Our analyses revealed that LSDV exhibited an 'open' pan-genome. Phylogenetic analysis unveiled distinct branches of LSDV evolution, signifying the prevalence of multiple lineages of LSDV across various regions in Asia. In addition, a reporter LSDV expressing eGFP directed by a synthetic poxvirus promoter was generated and used to evaluate the cell tropism of LSDV in various mammalian and avian cell lines. Our results demonstrated that LSDV replicated efficiently in several mammalian cell lines, including human A549 cells. In conclusion, our results underscore the necessity for strengthening LSD outbreak control measures and continuous epidemiological surveillance.

Abstract
Preliminary information about LSD virus isolated from the first outbreaks in Vietnam has been reported by our laboratory. In the current study, LSDV strain, LSDV/Vietnam/Langson/HL01(HL01) was further analyzed to provide a better understanding of this viral pathogen. HL01 LSDV strain was propagated at MOI 0.01 in MDBK cells and then given to cattle at dose of 106.5 TCID50/ml (2ml/animal). The production of proinflammatory (IFN-γ, IL-1α, and TNF-α) and anti-inflammatory (IL-6, IL-10, and TGF-ß1) cytokines were measured by real-time PCR, both In vitro and In vivo. The results demonstrated that HL01 strain caused the typical signs of LSD and LSDV In vitro and In vivo, respectively suggesting a virulent field LSDV strain. Additionally, different cytokine profiles were observed in these In vitro and In vivo studies. In MDBK cells, different cytokines profiles were observed in two phases: in the early phase, the expression levels of all examined cytokines were significantly increased at 6 h (p < 0.05). In the later phase, the peak levels of the cytokine secretion were recognized from 72 to 96 h, with the exception of IL-1α when compared to controls. In cattle, the expression levels of all six cytokines were significantly higher at day 7 following LSDV challenge (p < 0.05) when compared to controls, especially expression levels of TGF-β1 and IL-10. These findings suggest the important roles of these cytokines in protection against LSDV infections. Additionally, the data from diverse cytokine profiles followed by this LSDV strain challenge provides key understanding of the underlying cellular immune mechanisms in the host against LSDV infection In vitro and In vivo.

Abstract
Lumpy skin disease virus (LSDV), camelpox virus (CPV), and orf virus (ORFV) are members of the family Poxviridae. These viruses are usually isolated or produced in embryonated eggs or primary cells because continuous cell lines are less sensitive to infection. Disadvantages of the use of eggs or primary cells include limited availability, potential endogenous contaminants, and a limited ability to perform multiple passages. In this study, we developed a diploid cell culture from sheep embryonic hearts (EHs) and demonstrated its high proliferative and long-term storage capacities. In addition, we demonstrated its sensitivity to representatives of three genera of the family Poxviridae: Capripoxvirus (LSDV), Orthopoxvirus (CPV), and Parapoxvirus (ORFV). The cell culture had a doubling time of 24 h and reached 40 passages with satisfactory yield. This is comparable to that observed in primary lamb testis (LT) cells at passage 5 (P5). After infection, each poxvirus titer was 7.0-7.6 log TCID50/mL for up to five passages and approximately 6.8, 6.4, and 5.6 for the three viruses at P6-P25, P30, and P40, respectively. The sensitivity of sheep EH cells to poxvirus infection did not decrease after long-term storage in liquid nitrogen and was higher than that of primary LT cells, which are used for capripoxvirus and parapoxvirus detection and growth, and Vero cells, which are used for orthopoxvirus detection and growth. Thus, EH diploid cells are useful for poxvirus isolation and production without embryonated eggs or primary cells.

Abstract
Lumpy skin disease virus (LSDV) is a rapidly emerging pathogen in Asia, including China. Improving the propagation of LSDV is important for diagnostics and vaccine production. Our study identified and compared the LSDV susceptibility of eleven standard cells using western blot, indirect immune-fluorescence assay, quantitative PCR, and 50% tissue culture infectious dose. Our finding revealed that the LSDV strain could infect five cell lines and show a cytopathic effect. Furthermore, the hTERT-CSF cell line had the highest level of virus in the five cell models, followed by BHK-21, MDBK, Vero, and hTERT-ST. Hence, hTERT-CSF could be used as a candidate cell line for basic and applied research, clinical application, and LSDV vaccine development, providing a vital reference in LSDV and other viruses.

Abstract
Lumpy skin disease virus (LSDV) is a member of the Capripoxvirus genus, mainly infecting cattle and buffalo, which until relatively recently was only endemic in parts of Africa and then spread to the Middle East and lately Europe and Asia. Lumpy skin disease (LSD) is a notifiable disease with a serious impact on the beef industry as it causes mortality of up to 10% and has impacts on milk and meat production, as well as fertility. The close serological relationship between LSDV, goat poxvirus (GTPV) and sheep poxvirus (SPPV) has led to live attenuated GTPV and SPPV vaccines being used to protect against LSD in some countries. There is evidence that the SPPV vaccine does not protect from LSD as well as the GTPV and LSDV vaccines. One of the LSD vaccines used in Eastern Europe was found to be a combination of different Capripoxviruses, and a series of recombination events in the manufacturing process resulted in cattle being vaccinated with a range of recombinant LSDVs resulting in virulent LSDV which spread throughout Asia. It is likely that LSD will become endemic throughout Asia as it will be very challenging to control the spread of the virus without widespread vaccination.

Abstract
Primary sheep testicular Sertoli cells (STSCs) are ideal for investigating the molecular and pathogenic processes of capripoxvirus. However, the high cost of isolation and culture of primary STSCs, time-consuming operation, and short lifespan greatly limit their real-world application. In our study, the primary STSCs were isolated and immortalized by transfection of a lentiviral recombinant plasmid containing simian virus 40 (SV40) large T antigen. Androgen-binding protein (ABP) and vimentin (VIM) protein expression, SV40 large T antigen activity, proliferation assays, and apoptosis analysis results showed that immortalized large T antigen STSCs (TSTSCs) still had the same physiological characteristics and biological functions as primary STSCs. Moreover, immortalized TSTSCs had strong anti-apoptosis ability, extended lifespan, and enhanced proliferative activity compared to primary STSCs, which had not transformed in vitro and showed any signs of malignancy phenotype in nude mice. Besides, immortalized TSTSCs were susceptible to goatpox virus (GTPV), lumpy skin disease virus (LSDV), and Orf virus (ORFV). In conclusion, immortalized TSTSCs are useful in vitro models to study GTPV, LSDV, and ORFV in a wide range of ways, suggesting that it can be safely used in virus isolation, vaccine and drug screening studies in future.

Abstract
Goatpox, sheeppox, and peste-des-petits-ruminants (PPR) are economically important virus diseases affecting goats and sheep, which often cause coinfection/comorbidities in the field. Coinfection with these viruses leads to enhanced infection in natural scenarios in terms of morbidities and mortalities. Currently, individual live attenuated vaccines are being used to mitigate these diseases and research on combination vaccines for these diseases is encouraging. For the preparation of combination vaccines, vaccine strains of the peste-des-petits-ruminants virus (PPRV), goatpox virus (GTPV), and sheeppox virus (SPPV) are grown separately and GTPV + PPRV are mixed for vaccination of goats, and PPRV + SPPV for sheep. Growing capripox and PPRV strains in the same cells simultaneously without the titer loss will save the time and cost of production. In the current study, we have evaluated the coinfection kinetics of capripox virus and a PPRV using a candidate GTPV vaccine strain (originally caused infection in both goats and sheep in the field) and PPRV/Sungri/96 (vaccine strain) in Vero cells. At high multiplicity of infection (MOI), PPRV was excluded from coinfection by GTPV, whereas at a low multiplicity coexistence/accommodation was observed between PPRV and GTPV without loss of the titer. The results shed light on the possibility of the production of two vaccine strains in the same cells using the coinfection model economically.

Abstract
In August 2019, Lumpy skin disease broke out for the first time in Xinjiang, China, and then quickly spread to many provinces in China. Here, the virus was isolated from the skin scabs of affected cattle during June 2020 in Guangdong, China. Virus isolation, transmission electron microscopy and polymerase chain reaction identified lumpy skin disease virus (LSDV) in the skin crusts of sick cattle. For the isolation of LSDV, the most sensitive cell line is primary cattle testicular (PCT) cells, while Vero cells cannot be used for the isolation of LSDV. In addition, we evaluated the growth characteristics of LSDV. Compared with MDBK and Vero cells, LSDV produced the higher virus titers in PCT cells at 72 h. Phylogenetic analysis based on second-generation sequencing of the LSDV whole genome showed that the isolated virus (LSDV/MZGD/2020) is closely related to Asian strains and formed a new branch. LSDV/MZGD/2020 is also a vaccine recombinant strain, which is distinct from the recombinant strain found in Russia. Through RDP (Recombination Detection Program), Simplot and phylogenetic analyses, strong evidence for recombination events were found in Chinese field LSDV strains. The China LSDV/MZGD/2020 strain may be the result of multiple recombination events between the Neethling 2490 and Neethling vaccine LW 1959 strains. This study expanded our knowledge on the genetic diversity and evolution of LSDV. This article is protected by copyright. All rights reserved.

Evaluation of ELISA and VNT for sheeppox virus antibody detection and development of an immunoenzymatic quantitative method. J Immunol Methods 2022; 502:113226. [PMID: 35032520 DOI: 10.1016/j.jim.2022.113226] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 11/29/2021] [Accepted: 01/10/2022] [Indexed: 10/19/2022]
Abstract
Vaccination against sheep pox (SPV) is the most efficient tool to control spread of the disease and virus neutralization test (VNT) is the gold standard for vaccination monitoring. In the presented study, we evaluated the use of ELISA and VNT for quantification of SPV humoral response post vaccination. Results confirmed that VNT is more sensitive since ELISA did not detect 22% of positive tested sera, and VNT weak positive sera were either negative or doubtful by ELISA. The most sensitive cells to perform VNT were ESH-L instead of Lamb primary cells. We also investigated immunoperoxidase IPMA and immunofluorescence IFA assays for detection of SPV specific antibodies and IPMA showed higher antibody titers comparatively to IFA. VNT using ESH-L cells with immune-enzymatic revelation provide specific quantitative SPV antibody titers, easier to read in shorter incubation time.

Advancements in the Growth and Construction of Recombinant Lumpy Skin Disease Virus (LSDV) for Use as a Vaccine Vector. Vaccines (Basel) 2021; 9:vaccines9101131. [PMID: 34696239 PMCID: PMC8539341 DOI: 10.3390/vaccines9101131] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 01/13/2023] Open
Abstract
Attenuated vaccine strains of lumpy skin disease virus (LSDV) have become increasingly popular as recombinant vaccine vectors, to target both LSDV, as well as other pathogens, including human infectious agents. Historically, these vaccine strains and recombinants were generated in primary (lamb) testis (LT) cells, Madin–Darby bovine kidney (MDBK) cells or in eggs. Growth in eggs is a laborious process, the use of primary cells has the potential to introduce pathogens and MDBK cells are known to harbor bovine viral diarrhea virus (BVDV). In this study, data is presented to show the growth of an attenuated LSDV strain in baby hamster kidney (BHK-21) cells. Subsequently, a recombinant LSDV vaccine was generated in BHK-21 cells. Partial growth was also observed in rabbit kidney cells (RK13), but only when the vaccinia virus host range gene K1L was expressed. Despite the limited growth, the expression of K1L was enough to serve as a positive selection marker for the generation of recombinant LSDV vaccines in RK13 cells. The simplification of generating (recombinant) LSDV vaccines shown here should increase the interest for this platform for future livestock vaccine development and, with BHK-21 cells approved for current good manufacturing practice, this can be expanded to human vaccines as well.
