Abstract
BACKGROUND Cyprinid herpesvirus 2 (CyHV-2) is a pathogenic fish virus belonging to family Alloherpesviridae. The CyHV-2 gene encoding thymidine kinase (TK) is an important virulence-associated factor. Therefore, we aimed to investigate the biological function of open reading frame 55 (ORF55) in viral replication. METHODS Purified CyHV-2 ORF55 protein was obtained by prokaryotic expression, and the interacting peptide was screened out using phage display. Host interacting proteins were then predicted and validated. RESULTS ORF55 was efficiently expressed in the prokaryotic expression system. Protein and peptide interaction prediction and dot-blot overlay assay confirmed that peptides identified by phage display could interact with the ORF55 protein. Comparing the peptides to the National Center for Biotechnology Information database revealed four potential interacting proteins. Reverse transcription quantitative PCR results demonstrated high expression of an actin-binding Rho-activating protein in the latter stages of virus-infected cells, and molecular docking, cell transfection and coimmunoprecipitation experiments confirmed that it interacted with the ORF55 protein. CONCLUSION During viral infection, the ORF55 protein exerts its biological function through interactions with host proteins. The specific mechanisms remain to be further explored.

J Med Virol 2023; 95:e28228. [PMID: 36251622 DOI: 10.1002/jmv.28228] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 09/21/2022] [Accepted: 09/26/2022] [Indexed: 01/11/2023]
Abstract
Pseudorabies virus (PRV), as a neuroherpes virus, leads to heavy economic losses in the pig industry worldwide. This study was designed to establish recombinant PRV glycoprotein B (gB), C, and D proteins as PRV diagnostic antigens. The gB/C, gC/D, and gB/C/D fusion sequences were synthesized and inserted into pET-28a+ vector to generate the recombinant plasmids. The identified positive recombinant plasmids were transformed into BL21 Escherichia coli. The results of the polymerase chain reaction and enzyme digestion showed that the gB/C, gC/D, and gB/C/D fusion proteins were successfully expressed. An indirect sandwich ELISA was developed with the gB/C, gC/D, and gB/C/D as coating antigens. The results of indirect enzyme-linked immunosorbent assay (ELISA) analysis of 184 PRV-positive porcine sera showed that the positive coincidence rates of three recombinant proteins ELISAs relative to IDEXX kit were 98.25%, 95.32%, and 98.83%, and the negative coincidence rates were 85.71%, 75% and 100%, respectively. The inter and intra batch repeatability tests showed that the coefficient of variations of our kits were all less than 5%. Especially, the gB/C/D-ELISA has the highest specificity and sensitivity among the ELISA methods developed in this study. We established a series expression system of gB/C, gC/D, and gB/C/D antigen epitope genes and Recombinant protein-based indirect ELISA, providing new ideas for PV diagnosis and vaccine development.

Abstract
Retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are cytosolic pattern recognition receptors that initiate innate antiviral immunity. Recent reports found that duck RLRs significantly restrict duck plague virus (DPV) infection. However, the molecular mechanism by which DPV evades immune responses is unknown. In this study, we first found that the DPV UL41 protein inhibited duck interferon-β (IFN-β) production mediated by RIG-I and melanoma differentiation-associated gene 5 (MDA5) by broadly downregulating the mRNA levels of important adaptor molecules, such as RIG-I, MDA5, mitochondrial antiviral signalling protein (MAVS), stimulator of interferon gene (STING), TANK-binding kinase 1 (TBK1), and interferon regulatory factor (IRF) 7. The conserved sites of the UL41 protein, E229, D231, and D232, were responsible for this activity. Furthermore, the DPV CHv-BAC-ΔUL41 mutant virus induced more duck IFN-β and IFN-stimulated genes (Mx, OASL) production in duck embryo fibroblasts (DEFs) than DPV CHv-BAC parent virus. Our findings provide insights into the molecular mechanism underlying DPV immune evasion.

Abstract
The virion host shutoff (VHS) protein, encoded by the UL41 gene of herpes simplex virus (HSV), specifically degrades mRNA and induces host shutoff. VHS and its homologs are highly conserved in the Alphaherpesvirinae subfamily. However, the role of the duck plague virus (DPV) UL41 gene is unclear. In this study, we found that the DPV UL41 gene-encoded protein (pUL41) degrades RNA polymerase (pol) II-transcribed translatable RNA and induces protein synthesis shutoff. DPV pUL41 was dispensable for viral replication, but the UL41-deleted mutant virus exhibited a significant viral growth defect and plaque size reduction in Duck embryo fibroblast (DEF) cells. Furthermore, DPV pUL41 regulated viral mRNA accumulation to affect viral DNA replication, release and cell-to-cell spread.

Abstract
Duck enteritis virus (DEV) can successfully evade the host innate immune responses and establish a lifelong latent infection in the infected host. However, the study about how DEV escapes host innate immunity is still deficient up to now. In this study, for the first time, we identified a viral protein VP16 by which DEV can obviously downregulate the production of IFN-β in duck embryo fibroblast (DEF). Our results showed that ectopic expression of VP16 decreased duck IFN-β (duIFN-β) promoter activation and significantly inhibited the mRNA transcription of IFN-β. Further study showed that VP16 can also obviously inhibit the mRNA transcription of interferon-stimulated genes (ISGs), such as myxovirus resistance protein (Mx) and interferon-induced oligoadenylate synthetase-like (OASL). Furthermore, we found that this anti-interferon activity of VP16 depended on its N-terminus (aa1-200). Coexpression analysis revealed that VP16 selectively blocked duIFN-β promoter activity at the duIRF7 level rather than duIRF1. Based on the results of coimmunoprecipitation analysis (co-IP) and indirect immunofluorescence assay (IFA), VP16 was able to bind to duck IRF7 (duIRF7) directly, but did not interact with duck IRF1 (duIRF1) in vitro.

Abstract
Fowl cholera is a highly contagious disease within the global duck farming industry. This study aimed at formulating and evaluating the protective efficacy of a combination vaccine containing a recombinant outer membrane protein H (rOmpH) of Pasteurella multocida strain X-73 with a live attenuated duck plague vaccine into a single dose. Four groups of ducks received different treatments and the groups were labelled as non-vaccinated, combined vaccination, duck plague vaccination and rOmpH vaccination, respectively. The combined vaccination group was comprised of live attenuated duck plague commercial vaccine with 100 µg rOmpH to a total volume of 0.5 ml/duck/intramuscular administration. All groups were challenged with avian P. multocida strain X-73 via intranasal administration. In addition, blood samples were collected monthly over a period of 6 months to determine the appropriate antibody level by indirect ELISA. The indirect ELISA results in the combination vaccine group revealed that the average levels of the serum antibody against the duck enteritis virus (0.477 ± 0.155) and fowl cholera (0.383 ± 0.100) were significantly higher than those values in the non-vaccinated control group (0.080 ± 0.027 and 0.052 ± 0.017), respectively (P < 0.05). Moreover, all vaccinated ducks were effectively protected from fowl cholera. This preliminary study indicated that a combination vaccine did not affect the antibody response in the subjects while protecting the ducks against experimental P. multocida infection. This combination vaccine should be considered part of an alternative pre-treatment strategy that could replace the monovalent vaccine.

The recombinant DPV gI protein and rabbit IgG were used as capture reagents at the test line and control line, respectively. The detection limit of this assay was 1:256. Additionally, the CGS did not react with antisera from other common duck diseases, only reacting with anti-DPV serum and yielding a specific and strong red signal. 123 serum samples were tested by CGS and enzyme-linked immunosorbent assay (ELISA), and the results showed good agreement. The CGS test results can be observed in 15 min with the naked eye, should be suitable for clinical testing and large-scale detection.

Abstract
Alpha-herpesvirus thymidine kinase (TK) genes are virulence-related genes and are nonessential for viral replication; they are often preferred target genes for the construction of gene-deleted attenuated vaccines and genetically engineered vectors for inserting and expressing foreign genes. The enzymes encoded by TK genes are key kinases in the nucleoside salvage pathway and have significant substrate diversity, especially the herpes simplex virus 1 (HSV-1) TK enzyme, which phosphorylates four nucleosides and various nucleoside analogues. Hence, the HSV-1 TK gene is exploited for the treatment of viral infections, as a suicide gene in antitumor therapy, and even for the regulation of stem cell transplantation and treatment of parasitic infection. This review introduces the effects of α-herpesvirus TK genes on viral virulence and infection in the host and classifies and summarizes the current main application domains and potential uses of these genes. In particular, mechanisms of action, clinical limitations, and antiviral and antitumor therapy development strategies are discussed.

US10 Protein Is Crucial but not Indispensable for Duck Enteritis Virus Infection in Vitro. Sci Rep 2018; 8:16510. [PMID: 30405139 PMCID: PMC6220328 DOI: 10.1038/s41598-018-34503-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Accepted: 10/16/2018] [Indexed: 12/11/2022] Open
Abstract
To investigate the function of the duck enteritis virus (DEV) tegument protein US10, we generated US10 deletion and revertant mutants (ΔUS10 and US10FRT) via two-step RED recombination based on an infectious BAC clone of DEV CHv-BAC-G (BAC-G). In multistep growth kinetic analyses, ΔUS10 showed an approximately 100-fold reduction in viral titer, while the genome copies decreased only 4-fold compared to those of BAC-G. In one-step growth kinetic analyses, there were no significant differences in genome copies among BAC-G, ΔUS10 and US10FRT, but ΔUS10 still showed a 5- to 20-fold reduction in viral titer, and the replication defect of ΔUS10 was partially reversed by infection of US10-expressing cells. The transcription levels of Mx, OASL, IL-4, IL-6 and IL-10 in ΔUS10-infected duck embryo fibroblasts (DEFs) were significantly upregulated, while TLR3 was downregulated compared with those in BAC-G-infected DEFs. Taken together, these data indicated that US10 is vital for DEV replication and is associated with transcription of some immunity genes.

Abstract
Duck virus enteritis (DVE), also called duck plague, is one of the major contagious and fatal diseases of ducks, geese and swan. It is caused by duck enteritis virus (DEV)/Anatid herpesvirus-1 of the genus Mardivirus, family Herpesviridae, and subfamily Alpha-herpesvirinae. Of note, DVE has worldwide distribution, wherein migratory waterfowl plays a crucial role in its transmission within and between continents. Furthermore, horizontal and/ or vertical transmission plays a significant role in disease spread through oral-fecal discharges. Either of sexes from varying age groups of ducks is vulnerable to DVE. The disease is characterized by sudden death, vascular damage and subsequent internal hemorrhage, lesions in lymphoid organs, digestive mucosal eruptions, severe diarrhea and degenerative lesions in parenchymatous organs. Huge economic losses are connected with acute nature of the disease, increased morbidity and mortality (5%-100%), condemnations of carcasses, decreased egg production and hatchability. Although clinical manifestations and histopathology can provide preliminary diagnosis, the confirmatory diagnosis involves virus isolation and detection using serological and molecular tests. For prophylaxis, both live-attenuated and killed vaccines are being used in broiler and breeder ducks above 2 weeks of age. Since DEV is capable of becoming latent as well as shed intermittently, recombinant subunit and DNA vaccines either alone or in combination (polyvalent) are being targeted for its benign prevention. This review describes DEV, epidemiology, transmission, the disease (DVE), pathogenesis, and advances in diagnosis, vaccination and antiviral agents/therapies along with appropriate prevention and control strategies.

Preliminary study of the UL55 gene based on infectious Chinese virulent duck enteritis virus bacterial artificial chromosome clone. Virol J 2017; 14:78.

Abstract
Background Lethal Duck Enteritis Virus (DEV) infection can cause high morbidity and mortality of many species of waterfowl within the order Anseriformes. However, little is known about the function of viral genes including the conserved UL55 gene among alpha herpes virus due to the obstacles in maintenance and manipulation of DEV genome in host cells. Methods In this paper, we constructed an infectious bacteria artificial chromosome (BAC) clone of the lethal clinical isolate duck enteritis virus Chinese virulent strain (DEV CHv) by inserting a transfer vector containing BAC mini-F sequence and selection marker EGFP into UL23 gene using homologous recombination. UL55 deletion and its revertant mutant were generated by two-step RED recombination in E. coli on basis of rescued recombinant virus. The function of UL55 gene in DEV replication and its effect on distribution of UL26.5 protein were carried out by growth characteristics and co-localization analysis. Results The complete genome of DEV CHv can be stably maintained in E. coli as a BAC clone and reconstituted again in DEF cells. The generated UL55 deletion mutant based on DEV CHv-BAC-G displayed similar growth curves, plaque morphology and virus titer of its parental virus in infected Duck Embryo Fibroblast (DEF) cells. Immunofluorescence assay indicated that the loss of UL55 gene do not affect the distribution of UL26.5 protein in intracellular. These data also suggest infectious BAC clone of DEV CHv will facilitate the gene function studies of DEV genome. Conclusions We have successfully developed an infectious BAC clone of lethal clinical isolate DEV CHv for the first time. The generated UL55 gene mutant based on that demonstrated this platform would be a very useful tool for functional study of DEV genes. We found the least known DEV UL55 is dispensable for virus replication and UL26.5 distribution, and it could be a very promise candidate locus for developing bivalent vaccine. Experiment are now in progress for testifying the possibility of UL55 gene locus as an exogenous gene insertion site for developing DEV vectored vaccine.

Development and evaluation of indirect ELISAs for the detection of IgG, IgM and IgA1 against duck hepatitis A virus 1. J Virol Methods 2016; 237:79-85. [PMID: 27577105 DOI: 10.1016/j.jviromet.2016.08.019] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 08/22/2016] [Accepted: 08/26/2016] [Indexed: 11/16/2022]
Abstract
Duck hepatitis A virus 1 (DHAV-1) is the principal pathogen that causes duck viral hepatitis (DHV), a highly fatal infectious disease in ducklings. Given the importance of the humoral immune response in the clearance of DHAV-1, indirect enzyme-linked immunosorbent assays (I-ELISAs) to detect immune indices, including IgG, IgM and IgA1, were developed and evaluated in this study. The optimal concentrations of coating-antigen were 1.79μg/ml, 2.23μg/ml and 2.23μg/ml for IgG, IgM and IgA1, respectively. Meanwhile, the optimal dilutions of sera were 1:80, 1:40 and 1:40, respectively; and of the conjugates were 1:300, 1:1800 and 1:800, respectively. Based on these conditions, three linear regression equations, y=1.363+1.954x (r2=0.983), y=1.141+2.228x (r2=0.970) and y=1.103+1.559x (r2=0.995) were derived for IgG, IgM and IgA1, respectively. Analytical sensitivities of the new methods were 1:2560, 1:1280 and 1:640 for IgG, IgM and IgA1, respectively. The concordances between the I-ELISAs and serum-neutralization were 95.2% for IgG and IgA1, and 75% for IgM. Although there was a weak cross-reaction with DHAV-3 positive serum for the IgG and IgA1 tests, it didn't affect the ability to detect DHAV-1 specific antibodies. Thus, these new I-ELISAs were shown to be potentially convenient methods to survey the status of humoral immune response to DHAV-1.

Abstract
Aim: To evaluate the efficacy of recombinant outer membrane proteinC (rOmpC) based enzyme-linked immunoassay (ELISA) for the diagnosis of salmonellosis in poultry. Materials and Methods: Three antigens were prepared, and the indirect ELISA was standardized using the antigens and the antiserum raised in chicken against Omp and rOmpC. Sera were collected from a total of 255 apparently healthy field chickens and screened for the presence of Salmonella antibodies by this ELISA. Results: The sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of Omp revealed major polypeptides at 36, 42 and 52 kDa, and the rOmpC was evident by a single protein band of 43 kDa. The Omp and rOmpC antigen revealed an optimum concentration of 78 and 156 ng, respectively, in the assay, while the whole cell antigen gave an optimum reaction at a concentration of 106 organisms/ml. The test was found to be specific as it did not react with any of the antisera of seven other organisms. The developed ELISA detected Salmonella antibodies from 22 (8.62%) samples with rOmpC antigen, while 24 (9.41%) samples gave a positive reaction with both Omp and whole cell antigens. Conclusion: We suggest rOmpC based indirect ELISA as a suitable screening tool for serological monitoring of poultry flocks.

Abstract
Infecting ducks with duck hepatitis B virus (DHBV) is widely accepted as a relevant model for studying aspects of human HBV infection. However, efficient and sensitive diagnostic methods for the various infection models are limited. In order to provide a more simple and convenient method for serologic diagnosis, we improved the production of recombinant DHBV viral capsid protein (core protein) and then used it to develop an indirect enzyme-linked immunosorbent assay (ELISA) for detecting anti-DHBc antibodies (DHBcAg ELISA) in DHBV-infected ducks. Given the positive/negative cut-off value, the maximum dilution of duck sera in which anti-DHBc antibodies could be detected was 1:12,800. In addition, the DHBcAg ELISA displayed no cross reactivity with duck antisera against duck circovirus (DuCV), duck plague virus (DPV), duck hepatitis virus (DHV), duck swollen head septicemia virus (DSHSV), avian influenza virus (AIV), Riemerella anatipestifer, Salmonella anatum, or Escherichia coli. Furthermore, the coefficients of variation (CVs) of inter-assay and intra-assay experiments were both below than 10 %. When compared to PCR for accuracy on clinical samples from cases of suspected DHBV infection, the DHBcAg showed 95.45 % coincidence with PCR. In conclusion, recombinant DHBc was readily produced and used to establish a simple DHBcAg ELISA that provided a highly specific and sensitive method for analysis of clinical samples.

Abstract
In this study, a recombinant fusion antigen of duck enteritis virus (DEV) UL16 protein was expressed in Escherichia coli Rossetta (DE3). This target protein was used as a coating antigen to establish an indirect ELISA for detecting anti-DEV antibodies in serum samples from ducks. In the optimal method for the UL16-ELISA, the fusion protein was coated at 1.25μg/ml and duck serum samples were diluted at 1:160. The endpoint cut-off value of this assay was 0.598. The inter-assay and intra-assay coefficients of variation (CVs) were both lower than 10%. There was no cross-reaction with duck positive sera of either DHBV, DHV, RA, E. coli, Salmonella anatum, H5N1 or DSHDV. The assay was applied successfully to examine the suspected duck serum samples and showed 95.5% (73/76) identity with the serum neutralization test (SNT). The results showed that recombinant DEV UL16 protein could be used as a coating antigen and the developed UL16-ELISA approach was rapid, specific, sensitive and repetitive.

Abstract
Background Most of the previous research work had focused on the epidemiology and prevention of duck enteritis virus (DEV). Whilst with the development of protocols in molecular biology, nowadays more and more information about the genes of DEV was reported. But little information about DEV UL53 gene and glycoprotein K(gK) was known except our reported data. Results In our paper, the fluorescent quantitative real-time PCR(FQ-RT-PCR) assay and nucleic acid inhibition test were used to study the transcription characteristic of the DEV UL53 gene. Except detecting the mRNA of DEV UL53 gene, the product gK encoded by UL53 gene was detected through the expression kinetics of UL53 gene by the purified rabbit anti-UL53 protein polyclonal antibodies. Western-blotting and indirect immunofluorescence assays were used to detect gK. From the results of these experiments, the UL53 gene and gK were respectively identified as a late gene and a really late protein. On the other hand, the indirect immunofluorescence assay provided another information that the intracellular localization of DEV gK was mainly distributed in cytoplasm. Conclusions By way of conclusions, we conceded that DEV UL53 gene is a really late gene, which is coincident with properties of UL53 homologs from other herpesvirus, such as ILTV(Infectious Laryngotracheitis virus) and HSV-1(Herpes simplex virus type 1). The properties of intracellular localization about gK protein provided a foundation for further functional analysis and further studies will be focused on constructing of the UL53 gene DEV mutant.

Abstract
Background Some UL45 gene function of Herpesvirus was reported. While there was no any report of the duck enteritis virus (DEV) UL45 protein as yet. Results The UL45 gene and des-transmembrane domain of UL45 (named UL45Δ gene, 295-675bp of UL45) of DEV were amplified by PCR and subcloned into the prokaryotic expression vector pET-32a(+). The constructed recombinant plasmids were transformed into the host strain BL21(DE3) PLysS and induced by IPTG. SDS-PAGE analysis showed the UL45 gene couldn't express while UL45Δ gene was highly expressed. His Purify Kit or salting-out could purify the protein effectively. Using the purified protein to immunize New-Zealand rabbits and produce polyclonal antibody. The agar diffusion reaction showed the titer of antibody was 1:32. Western blot analysis indicated the purified rabbit anti-UL45Δ IgG had a high level of specificity and the UL45 gene was a part of DEV genome. The transcription phase study of UL45 gene showed that expression of UL45 mRNA was at a low level from 0 to 18 h post-infection (pi), then accumulated quickly at 24 h pi and peaked at 42 h pi. It can be detected till 72 h pi. Besides, western blot analysis of purified virion and different viral ingredients showed that the UL45 protein resided in the purified virion and the viral envelope. Conclusions The rabbit anti-UL45Δ IgG was produced successfully and it can serve as a good tool for penetrating studies of the function of DEV UL45 protein. The transcription phase and protein characteristics analysis indicated that DEV UL45 gene was a late gene and UL45 protein may be a viral envelope protein.
