Immunogenic Cross-Reactivity between Goose and Muscovy Duck Parvoviruses: Evaluation of Cross-Protection Provided by Mono- or Bivalent Vaccine. Vaccines (Basel) 2022; 10:vaccines10081255. [PMID: 36016142 PMCID: PMC9413244 DOI: 10.3390/vaccines10081255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 07/26/2022] [Accepted: 08/01/2022] [Indexed: 12/04/2022] Open
Abstract
To investigate the immunogenic cross reactivity between goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV), cross-neutralization was carried out with serum samples collected from birds after infection with one of the two waterfowl parvoviruses. The significantly higher virus neutralization titer obtained against the homologous virus than against the heterologous one suggests important differences between the GPV and MDPV antigenic make up that affects the induced protective virus-neutralizing antibody specificity. This was further confirmed by cross-protection studies carried out in waterfowl parvovirus antibody-free Muscovy ducks immunized at one day of age with whole-virus inactivated oil-emulsion vaccines containing either GPV or MDPV as a monovalent vaccine, or both viruses as a bivalent vaccine. Protection against the clinical disease (growth retardation and feathering disorders) provided by the monovalent vaccine was complete against homologous virus challenge at 2 weeks post-vaccination, while the protection against the heterologous virus challenge was significantly lower (p < 0.001). Only the bivalent vaccine containing both goose and Muscovy duck parvoviruses in an inactivated form protected the birds (90−100%) against both waterfowl parvoviruses that can cause disease in Muscovy ducks. Both the cross-neutralization and cross-protection results indicated that adequate protection in Muscovy ducks against the two waterfowl parvoviruses could be achieved only with a vaccine containing both goose and Muscovy duck parvoviruses. Our results showed that the inactivated vaccine applied at one day of age could induce fast immunity (by 2 weeks post-vaccination), providing complete clinical protection in maternal antibody-free birds. It was also demonstrated that day-old vaccination of ducks with maternal antibodies with bivalent vaccine induced active immunity, resulting in 90 to 100% protection by 3 weeks of age, after the decline of maternal antibodies. A booster vaccination administered at 3 weeks of age following the day-old vaccination resulted in a strong and durable immunity against the clinical disease during the susceptible age of the birds.

Abstract
Abstract
Derzsy’s disease and Muscovy duck parvovirus disease have become common diseases in waterfowl culture in the world and their potential to cause harm has risen. The causative agents are goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV), which can provoke similar clinical symptoms and high mortality and morbidity rates. In recent years, duck short beak and dwarfism syndrome has been prevalent in the Cherry Valley duck population in eastern China. It is characterised by the physical signs for which it is named. Although the mortality rate is low, it causes stunting and weight loss, which have caused serious economic losses to the waterfowl industry. The virus that causes this disease was named novel goose parvovirus (NGPV). This article summarises the latest research on the genetic relationships of the three parvoviruses, and reviews the aetiology, epidemiology, and necropsy characteristics in infected ducks, in order to facilitate further study.

The first detection and characterization of goose parvovirus (GPV) in Turkey. Trop Anim Health Prod 2020; 53:36.

Abstract
Derzsy's disease, which is seen in goslings (Anser anser domestica) and Muscovy ducks (Cairina moschata), progresses to high mortality and causes significant yield losses. The disease agent is goose parvovirus (GPV), which is common in countries with waterfowl production. It has not previously been reported in Turkey. Using qPCR and sequencing of the VP3 protein-encoding gene, GPV is identified as the causative agent of high mortality among geese between 2018 and 2019. The VP3 sequences were also compared with the similar GenBank sequences phylogenetically. All the sequences were found to be most similar (98.90%) with Polish and Taiwan GPV strains. Phylogenetic analysis of the VP3 gene in strains in Turkey and comparison with strains from other countries demonstrated that the Turkish strains are native to the geography and circulated locally. This study detected the presence of the GPV gene for the first time in Turkey and demonstrated the importance of comparing the vaccine strain and wild type.

Metagenomic characterisation of avian parvoviruses and picornaviruses from Australian wild ducks. Sci Rep 2020; 10:12800.

Abstract
Ducks can shed and disseminate viruses and thus play a role in cross-species transmission. In the current study, we detected and characterised various avian parvoviruses and picornaviruses from wild Pacific black ducks, Chestnut teals, Grey teals and Wood ducks sampled at multiple time points from a single location using metagenomics. We characterised 46 different avian parvoviruses belonging to three different genera Dependoparvovirus, Aveparvovirus and Chaphamaparvovirus, and 11 different avian picornaviruses tentatively belonging to four different genera Sicinivirus, Anativirus, Megrivirus and Aalivirus. Most of these viruses were genetically different from other currently known viruses from the NCBI dataset. The study showed that the abundance and number of avian picornaviruses and parvoviruses varied considerably throughout the year, with the high number of virus reads in some of the duck samples highly suggestive of an active infection at the time of sampling. The detection and characterisation of several parvoviruses and picornaviruses from the individual duck samples also suggests co-infection, which may lead to the emergence of novel viruses through possible recombination. Therefore, as new and emerging diseases evolve, it is relevant to explore and monitor potential animal reservoirs in their natural habitat.

Abstract
Both Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) can cause high mortality and morbidity in Muscovy ducklings. MDPVs and GPVs share high nucleotide identity, which can cause errors during differential diagnosis. In this study, the NS genes of both MDPVs and GPVs were chosen for the design of specific primers after genetic comparison. Only three primers (GF1, MF1 and MGR1) were designed for the duplex PCR assay: GF1 is specific for GPV only; MF1 is specific for MDPV only; and MGR1 is highly conserved for both MDPV and GPV. After a series of optimization experiments, the duplex PCR assay amplified a 161-bp fragment specifically for GPV, a 1197-bp fragment specifically for MDPV, and two fragments (161-bp and 1197-bp) for both GPV and MDPV. The lowest detection limit was 103 copies/μl. No amplification was obtained using nucleic acids from other pathogens (including DAdV-A, DuCV, DEV, GHPV, R.A., E. coli., P.M. and S.S.) occurring in Muscovy ducks. Application of the duplex PCR assay in field samples showed that even one-day-old Muscovy ducklings were both MDPV-positive and GPV-positive. In conclusion, a duplex PCR assay for the simultaneous detection and differentiation of MDPV and GPV was established using only three highly specific primers. Our finding suggested that country-wide vaccination with MDPV and GPV vaccines in waterfowls are necessary.

Abstract
Background In Poland, the leader in goose production in Europe, goose parovirus infection, or Derzsy’s disease (DD), must be reported to the veterinary administration due to the serious economic and epizootic threat to waterfowl production. Prophylactic treatment for DD includes attenuated live or inactivated vaccines. Moreover, the control of DD includes the monitoring of maternal derived antibody (MDA) levels in the offspring and antibody titers in the parent flock after vaccination. The aim of this study was to develop an ELISA for the detection of goose parvovirus (GPV) antibodies. Results Two recombinant protein fragments derived from VP3 (viral protein 3) GPV, namely VP3ep6 and VP3ep4–6 with a mass of 20.9 and 32.3 kDa, respectively, were produced using an Escherichia coli expression system. These proteins were purified by one-step nickel-affinity chromatography, which yielded protein preparations with a purity above 95%. These recombinant proteins were useful in the detection of serum anti-GPV antibodies, and this was confirmed by Western blotting. However, recombinant VP3ep4–6 protein showed a greater ability to correctly identify sera from infected geese. In the next stage of the project, a pool of 166 goose sera samples, previously examined by a virus neutralization test (VN), was tested. For further studies, one recombinant protein (VP3ep4–6) was selected for optimization of the test conditions. After optimization, the newly developed ELISA was compared to other serological tests, and demonstrated high sensitivity and specificity. Conclusion In conclusion, the VP3ep4–6 ELISA method described here can be used for the detection of antibodies to GPV in serum.

Abstract
Background Waterfowl parvoviruses, including goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV), can cause seriously diseases in geese and ducks. Developing a fast and precise diagnosis assay for these two parvoviruses is particularly important. Results A duplex SYBR Green I-based quantitative real-time PCR assay was developed for the simultaneous detection and differentiation of GPV and MDPV. The assay yielded melting curves with specific single peak (Tm = 87.3 ± 0.26 °C or Tm = 85.4 ± 0.23 °C) when GPV or MDPV was evaluated, respectively. When both parvoviruses were assessed in one reaction, melting curves with specific double peaks were yielded. Conclusion This duplex quantitative RT-PCR can be used to rapid identify of GPV and MDPV in field cases and artificial trials, which make it a powerful tool for diagnosing, preventing and controlling waterfowl parvovirus infections.

Abstract
AIMS To evaluate the effect of a DNA priming and protein boosting immunization scheme in ducks. METHODS AND RESULTS Pekin ducks were immunized with pTCY/VP2 DNA vaccine; on day 14 (D14) after primary immunization, the ducks were boosted with either the same vaccine (DNA + DNA) or the rVP2 vaccine (DNA + rVP2). CpG oligodeoxynucleotides containing three copies of GACGTT motifs were used as the adjuvant in the vaccines. Compared with unimmunized controls, both immunization schemes significantly increased the titre of antigen-specific antibodies, lymphocyte proliferation index, percentage of CD4+ and CD8+ cells in peripheral blood mononuclear cells (PBMCs) and mRNA expression of interferon (IFN)-α, IFN-γ, interleukin (IL)-6 and IL-12 in antigen-stimulated PBMCs. Furthermore, compared with the DNA + DNA homologous scheme, the DNA + rVP2 heterologous scheme significantly increased lymphocyte proliferation, percentage of CD4+ and CD8+ cells in PBMCs and upregulation of mRNA expression of cytokines 2 weeks after the boost (D28). CONCLUSIONS The DNA + rVP2 immunization scheme enhanced immune responses, mainly Th1 type, against parvovirus in ducks. SIGNIFICANCE AND IMPACT OF THE STUDY The DNA priming and protein boosting heterologous immunization strategy can be applied to develop vaccines against viral infections in ducks. It can potentially be used in breeding ducks because of long-term immunity may confer protection for ducklings.

Abstract
BACKGROUND Muscovy duck parvovirus (MDPV) causes high mortality and morbidity in Muscovy ducks, with the pathogenesis of the virus still unknown in many respects. Specific MDPV detection is often rife with false positive results because of high identity at the genomic nucleotide level and antigenic similarity with goose parvovirus (GPV). The objective of this study was to develop a sensitive, highly specific, and repeatable TaqMan-based real-time PCR (qPCR) assay for facilitating the molecular detection of MDPV. RESULTS The specific primers and probe were designed based on the conserved regions within MDPVs, but there was a variation in GPVs of the nonstructural (NS) genes after genetic comparison. After the optimization of qPCR conditions, the detection limit of this qPCR assay was 29.7 copies/μl. The assay was highly specific for the detection of MDPV, and no cross-reactivity was observed with other non-targeted duck-derived pathogens. Intra- and inter-assay variability was less than 2.21%, means a high degree of repeatability. The diagnostic applicability of the qPCR assay was proven that MDPV-positive can be found in cloacal swabs samples, Muscovy duck embryos and newly hatched Muscovy ducklings. CONCLUSIONS Our data provided incidents that MDPV could be possible vertically transmitted from breeder Muscovy ducks to Muscovy ducklings. The developed qPCR assay in the study could be a reliable and specific tool for epidemiological surveillance and pathogenesis studies of MDPV.

Abstract
Clinical observations and diagnostic procedures carried out to elucidate the cause of high mortality in 2-8-wk-old ornamental ducks (mandarin, wood, falcated, and silver teal ducks) are described. At necropsy, ducklings showed general pallor of skeletal and heart muscles, subcutaneous gelatinous transudates, pericarditis, ascites, and severe edema and hyperemia of lungs. Histopathologic examination revealed that the most important changes were located in the crop, bursa of Fabricius, and lungs with presence of amorphic basic intracytoplasmic inclusions. No bacteria or fungi could be detected from affected organs and ascitic fluid. Viral diagnosis included molecular detection for the presence of goose parvovirus (GPV), circovirus, avian influenza, herpesviruses, paramyxovirus, reovirus, and polyomavirus. Both GPV and circovirus could be detected by real-time PCR and nested broad-spectrum PCR, respectively. Phylogenetically, full-length nucleotide sequence of GPV showed a close similarity ranging from 95.6% to 97.9% with European and Asian pathogenic GPV. On the other hand, the detected circovirus showed nucleotide identity of 90% to 98% with goose circoviruses (GoCVs). This is the first report of GoCVs and GPV in ornamental ducks. The concurrence of GPV and GoCV infections is thought to contribute to the high mortality.

Abstract
We previously demonstrated that ducks immunized with recombinant VP2 protein (rVP2) of parvovirus in conjunction with CpG oligodeoxynucleotides (ODN) containing three copies of GACGTT motifs had significantly ([Formula: see text]) increased antibody titer, splenocyte proliferation index, amount of CD4[Formula: see text] and CD8[Formula: see text] cells, and mRNA expression of cytokines (IFN-[Formula: see text], IFN-[Formula: see text], IL-6, and IL-8) in comparison with those immunized with rVP2 plus aluminum hydroxide. In the present study, ducklings hatched from eggs produced by ducks immunized with rVP2 and various adjuvants were used to analyze the passive immunity of maternal antibodies followed by an experimental challenge with live parvovirus. Results indicated that the titer of VP2-specific antibodies and the body weight of ducklings produced from ducks immunized with rVP2[Formula: see text]CpG ODN were significantly ([Formula: see text]) higher than those of ducklings from other groups at day 7 after the challenge. The autopsy report revealed that ducklings in groups other than rVP2[Formula: see text]CpG ODN and rVP2[Formula: see text]mock had hemorrhage in the liver and intestinal mucous at 11 days after the challenge, and the presence of parvovirus was confirmed by PCR using parvovirus-specific primers. Therefore, immunizing ducks with rVP2[Formula: see text]CpG ODN containing three copies of GACGTT motifs is able to enhance the passive immunity, which protects their ducklings from parvovirus infection.

Abstract
Background Waterfowl parvovirus (WPV) infection causes high mortality and morbidity in both geese (Anser anser) and Muscovy ducks (Cairina moschata), resulting in significant losses to the waterfowl industries. The VP3 protein of WPV is a major structural protein that induces neutralizing antibodies in the waterfowl. However, B-cell epitopes on the VP3 protein of WPV have not been characterized. Methods and Results To understand the antigenic determinants of the VP3 protein, we used the monoclonal antibody (mAb) 4A6 to screen a set of eight partially expressed overlapping peptides spanning VP3. Using western blotting and an enzyme-linked immunosorbent assay (ELISA), we localized the VP3 epitope between amino acids (aa) 57 and 112. To identify the essential epitope residues, a phage library displaying 12-mer random peptides was screened with mAb 4A6. Phage clone peptides displayed a consensus sequence of YxRFHxH that mimicked the sequence 82Y/FNRFHCH88, which corresponded to amino acid residues 82 to 88 of VP3 protein of WPVs. mAb 4A6 binding to biotinylated fragments corresponding to amino acid residues 82 to 88 of the VP3 protein verified that the 82FxRFHxH88 was the VP3 epitope and that amino acids 82F is necessary to retain maximal binding to mAb 4A6. Parvovirus-positive goose and duck sera reacted with the epitope peptide by dot blotting assay, revealing the importance of these amino acids of the epitope in antibody-epitope binding reactivity. Conclusions and Significance We identified the motif FxRFHxH as a VP3-specific B-cell epitope that is recognized by the neutralizing mAb 4A6. This finding might be valuable in understanding of the antigenic topology of VP3 of WPV.

Abstract
Waterfowl parvoviruses are divided into Muscovy duck parvoviruses (MDPVs) and goose parvoviruses (GPVs). Phylogenetic analysis based on structural gene nucleotide sequences showed that the strains of three GPVs (DY, PT and D strains) and two MDPVs (GX5 and SAAH-SHNH) are closely related and formed one cluster. Recombination analysis showed that recombination between GPV-GDFsh and MDPV-89384/FRANCE strains led to five recombinant strains: GPV-DY, GPV-PT, GPV-D, MDPV-GX5 and MDPV-SAAH-SHNH. The recombinant event was confirmed using the Simplot program and phylogenetic analysis. This is the first comprehensive investigation of recombination between MDPV and GPV structural genes.

Abstract
To investigate the possible role of recombination in the evolution of Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) in Taiwan, we analyzed a potentially significant recombination event that occurred only in GPV by comparing thirteen complete sequences of the capsid gene VP2 of GPV and MDPV. The recombination event occurred between GPV strain 06-0239 as the minor parent and strains 99-0808 as the major parent, which resulted in the GPV recombinant V325/TW03. GPV V325/TW03 is likely to represent a new genotype among the Taiwanese GPV strains. This represents the first evidence that intergenotype recombination within the VP2 gene cluster contributes to the genetic diversity of the VP2 genes of Taiwanese GPV field strains.

Abstract
The full-length genome of strain SAAS-SHNH, a MDPV isolated from Muscovy Duck in Shanghai, has been sequenced and shown to share 93.7% nucleotide identity with MDPV strain FM (NC_006147). Two putative genetic recombination events were identified as occurring within the 419-610 nt and 3113-4241 nt regions of the SAAS-SHNH genome which, for the first time, provide evidence of recombination between MDPVs and GPVs.

Abstract
We report a novel goose parvovirus (MDGPV/PT) isolated from an affected Muscovy duck in Fujian Province, China. In this study, the NS1 sequence analyses indicated a close genetic relationship between MDGPV/PT and Muscovy duck parvovirus (MDPV) strains, although MDGPV/DY, which was isolated from a Muscovy duck in 2006 in Sichuan Province, could be divided into GPV-related groups. Phylogenetic analysis showed that except for differences in the NS1 gene, MDGPV strains PT and DY are closely related to a parvovirus that infects domestic waterfowls. This is the first demonstration of recombination between goose and Muscovy duck parvoviruses in nature, and MDGPV/PT might have led to the generation of a novel waterfowl parvovirus strain circulating in Muscovy duck flocks in China.

Abstract
Background The VP3 protein of goose parvovirus (GPV) or Muscovy duck parvovirus (MDPV), a major structural protein, can induce neutralizing antibodies in geese and ducks, but monoclonal antibodies (MAbs) against VP3 protein has never been characterized. Results Three hybridoma cell lines secreting anti-GPV VP3 MAbs were obtained and designated 4A8, 4E2, and 2D5. Immunoglobulin subclass tests differentiated them as IgG2b (4A8 and 4E2) and IgG2a (2D5). Dot blotting assays showed that three MAbs reacted with His-VP3 protein in a conformation-independent manner. A competitive binding assay indicated that the MAbs delineated two epitopes, A and B of VP3. Immunofluorescence assay showed that MAbs 4A8, 4E2, and 2D5 could specifically bind to goose embryo fibroblast cells (GEF) or duck fibroblast cells (DEF) infected with GPV and MDPV. Dot blotting also showed that the MAbs recognized both nature GPV and MDPV antigen. Western blotting confirmed that the MAbs recognized VP3 proteins derived from purified GPV and MDPV particles. The MAbs 4A8 and 2D5 had universal reactivity to heterologous GPV and MDPV tested in an antigen-capture enzyme-linked immunosorbent assay. Conclusions Preparation and characterization of these the MAbs suggests that they may be useful for the development of a MAb-capture ELISA for rapid detection of both GPV and MDPV. Virus isolation and PCR are reliable for detecting GPV and MDPV infection, but these procedures are laborious, time-consuming, and requiring instruments. These diagnosis problems highlight the ongoing demand for rapid, reproducible, and automatic methods for the sensitive detection of both GPV and MDPV infection.

Quantitative analysis of waterfowl parvoviruses in geese and Muscovy ducks by real-time polymerase chain reaction: correlation between age, clinical symptoms and DNA copy number of waterfowl parvoviruses.

Abstract
Background Waterfowl parvoviruses cause serious loss in geese and ducks production. Goose parvovirus (GPV) is infectious for geese and ducks while Muscovy duck parvovirus (MDPV) infects Muscovy ducks only. So far, for these viruses' sensitive detection polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP) were applied. However, there was no molecular biology method for both waterfowl parvoviruses detection and quantification which could unify the laboratory procedures. The level of GPV and MDPV replication and distribution plays a significant role in the parvoviral infection progress and is strictly correlated to clinical symptoms. Meanwhile, experiments conducted previously on GPV distribution in geese, performed as animal trial, did not involve epidemiological data from the disease field cases. The study on the correlation between age, clinical symptoms and viral DNA copy number may be benefitable in understanding the GPV and MDPV infection. Such data may also aid in determination of the stage and severity of the infection with parvoviruses. Therefore the aim of this study was to develop quantitative real-time PCR for parallel detection of GPV and MDPV in geese and Muscovy ducks and to determine the correlation between the age of the infected birds, clinical symptoms and DNA copy number for the estimation of the disease stage or severity. Results In order to develop quantitative real-time PCR the viral material was collected from 13 farms of geese and 3 farms of Muscovy ducks. The designed primers and Taqman probe for real-time PCR were complementary to GPV and MDPV inverted terminal repeats region. The pITR plasmid was constructed, purified and used to prepare dilutions for standard curve preparation and DNA quantification. The applied method detected both GPV and MDPV in all the examined samples extracted from the heart and liver of the infected birds. The conducted correlation tests have shown relationship between age, clinical symptoms during parvoviral infection and the DNA copy number of these pathogens. The method allowed for a sensitive detection of GPV and MDPV even in 1-week old infected goslings or 2-week old ducklings before observation of any disease symptoms. Conclusions The developed method was found to be a valuable tool for the unification of laboratory procedures and both parvoviruses parallel detection and quantification. The conducted analysis revealed significant correlation between the age of the infected birds, the observed clinical symptoms and DNA copy number of GPV and MDPV in the examined organs. The obtained data may aid in better understanding of the pathogenesis and epidemiology of Derzsy's disease and 3-w disease as well as estimation of the infection's severity and stage of the disease.

Abstract
Recombinant parvovirus VP2 (rVP2) was formulated with different types of adjuvant, including aluminum adjuvant and CpG oligodeoxynucleotides (ODNs), and the immunological responses after vaccination in ducks were examined. In comparison with the control group, production of rVP2-specific antibodies, expression of cytokines in peripheral blood mononuclear cells (PBMC) stimulated by rVP2, and percentage of CD4(+)/CD8(+) cells in PBMC were significantly increased in ducks immunized with rVP2 formulated with CpG ODNs containing 3 copies of GACGTT motif. CpG ODNs with GACGTT motifs might be used to improve the efficacy of vaccines for ducks.

Abstract
The aim of this study was the assessment of the genetic variance of Derzy's disease (GPV) strains isolated from cases occurring in Poland. The nucleotide and predicted aminoacid sequences of VP2 and VP3 surface proteins of the Polish GPV strains were compared with other strains previously isolated in Hungary, France, Germany, China and Taiwan. The observed genetic variance of the aminoacid sequence within the group of Polish strains was low and reached 5% of the overall analysed sequence. Considerable differences in aminoacid sequence were found in the case of Polish field GPV strains and Muscovy duck parvovirus strain MDPV FM which was also analysed in this study. The conducted investigations confirmed the presupposition that Polish GPV strains and strains previously isolated in Hungary and France share a common origin.

Abstract
The VP3-encoding gene of goose parvovirus (GPV) Ep22 strain was cloned and expressed in Escherichia coli. The GPV VP3-encoding gene was 1605 bp in length, and it encoded a 534 amino acid protein with a predicted molecular mass of 59.9 kDa. The VP3 fusion protein expressed in E. coli was detected by goose and Muscovy duck anti-parvovirus polyclonal sera. In addition, an ELISA (VP3-ELISA) using the VP3 protein as the coating antigen for the detection of antibodies to GPV in geese and antibodies to Muscovy duck parvovirus (MDPV) in Muscovy ducks was developed. Compared to the virus neutralization test, the specificity and sensitivity of the VP3-ELISA was 90.2% and 95.2% for goose sera and 91.8% and 96.7% for Muscovy duck sera, respectively. The VP3-ELISA did not react with the anti-sera to other goose or duck pathogens, indicating that this protein is specific for the reorganization of goose or duck anti-parvovirus antibodies. Cross-reactivity between immunoglobulin G antibodies from geese and Muscovy ducks was also tested, and the results reflected the phylogenetic distance between these two birds when using the ELISA. In conclusion, the VP3-ELISA is a sensitive and specific method for detecting antibodies against GPV or MDPV.

Abstract
BACKGROUND Goose parvovirus (GPV) is a Dependovirus associated with latent infection and mortality in geese. Currently, it severely affects geese production worldwide. The objective of this study was to develop a fluorescent quantitative real-time polymerase chain reaction (PCR) (FQ-PCR) assay for fast and accurate quantification of GPV DNA in infected goslings, which can aid in the understanding of the regular distribution pattern and the nosogenesis of GPV in vivo. RESULTS The detection limit of the assay was 2.8 x 10(1) standard DNA copies, with a sensitivity of 3 logs higher than that of the conventional gel-based PCR assay targeting the same gene. The real-time PCR was reproducible, as shown by satisfactory low intraassay and interassay coefficients of variation. CONCLUSION The high sensitivity, specificity, simplicity, and reproducibility of the GPV fluorogenic PCR assay, combined with a high throughput, make this method suitable for a broad spectrum of GPV etiology-related applications.

Between 1997 and 1999 several cases of a new disease in Muscovy ducks were reported in Pennsylvania, USA. The cases were characterized by locomotor dysfunction, weakness, recumbency, 40 to 60% morbidity and 10 to 40% mortality. The most characteristic microscopic lesions were moderate to severe degenerative rhabodomyopathy. In order to characterize the aetiological agent, virus isolation was attempted from the spleen, liver, heart, skeletal muscle and intestine by inoculation of 14-day-old Muscovy duck embryos with tissue homogenates. Deaths occurred on the second egg passage and parvoviruses were isolated by serial passage of allantoic fluid from dead embryos and then in Muscovy duck embryo fibroblast (MDEF) cultures. Parvovirus particles were observed in allantoic fluids and supernatants of MDEF cultures by transmission electron microscopy. Two genomic fragments, comprising 1108 nucleotides of the right open reading frame that codes for the structural viral proteins 1, 2 and 3, were amplified by polymerase chain reaction from one of the isolates, Muscovy duck parvovirus (MDPV)/PSU-31010. Comparison of this fragment with available sequences of other MDPV and related goose parvovirus (GPV) isolates showed that it had only 84.5% sequence identity with other MDPV isolates and 84.6% identity with the GPV isolates. This region shares over 99% identity among previously sequenced MDPV isolates and 95% identity among the related GPV isolates. This suggests that MDPV/PSU-31010 is divergent from all other sequenced MDPV and GPV isolates, and may represent a new group of avian parvoviruses.

Abstract
While there are a number of methods available for detection of antibodies against waterfowl parvoviruses, none is able to differentiate responses against the capsid and non-structural proteins. To enable this, the capsid and non-structural proteins of goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV) were expressed in Escherichia coli. These proteins were purified and used as antigens in western blotting assays of antibodies against GPV and MDPV. The results showed that 94.7% of the goose and 90.0% of the duck sera collected from the field contained antibodies against GPV or MDPV. Moreover, these sera could be classified into distinct groups based on differences in patterns of western blot reactivity. These different patterns might indicate different stages in infection. Western blotting assays of sera collected from experimentally infected ducks showed that antibodies against the non-structural protein appeared first after infection, followed by antibodies against the capsid protein. It was concluded that the recombinant capsid and non-structural proteins might serve as useful antigens for assays for antibodies against GPV and MDPV. Moreover, because these assays could discriminate between antibodies against the non-structural protein and those against the capsid protein, they may be useful in differentiating vaccinated from infected birds when recombinant capsid protein is used as the vaccine.

Abstract
To understand the genetic variations between the field strains of waterfowl parvoviruses and their attenuated derivatives, we analyzed the complete nucleotide sequences of the viral protein 1 (VP1) genes of nine field strains and two vaccine strains of waterfowl parvoviruses. Sequence comparison of the VP1 proteins showed that these viruses could be divided into goose parvovirus (GPV) related and Muscovy duck parvovirus (MDPV) related groups. The amino acid difference between GPV- and MDPV-related groups ranged from 13.1% to 15.8%, and the most variable region resided in the N terminus of VP2. The vaccine strains of GPV and MDPV exhibited only 1.2% and 0.3% difference in amino acid when compared with their parental field strains, and most of these differences resided in residues 497-575 of VP1, suggesting that these residues might be important for the attenuation of GPV and MDPV. When the GPV strains isolated in 1982 (the strain 82-0308) and in 2001 (the strain 01-1001) were compared, only 0.3% difference in amino acid was found, while MDPV strains isolated in 1990 (the strain 90-0219) and 1997 (the strain 97-0104) showed only 0.4% difference in amino acid. The result indicates that the genome of waterfowl parvovirus had remained highly stable in the field.

Abstract
Production of large quantities of recombinant adeno-associated virus (AAV) is difficult and not cost-effective. To overcome this problem, we have explored the feasibility of creating a recombinant AAV encoding a 6xHis tag on the VP3 capsid protein. We generated a plasmid vector containing a six-His (6xHis)-tagged AAV VP3. A second plasmid vector was generated that contained the full-length AAV capsid capable of producing VP1 and VP2, but not VP3 due to a mutation at position 2809 that encodes the start codon for VP3. These plasmids, necessary for production of AAV, were transfected into 293 cells to generate a 6xHis-tagged VP3mutant recombinant AAV. The 6xHis-tagged VP3 did not affect the formation of AAV virus, and the physical properties of the 6xHis-modified AAV were equivalent to those of wild-type particles. The 6xHis-tagged AAV did not affect the production titer of recombinant AAV and could be used to purify the recombinant AAV using an Ni-nitrilotriacetic acid column. Addition of the 6xHis tag did not alter the viral tropism compared to wild-type AAV. These observations demonstrate the feasibility of producing high-titer AAV containing a 6xHis-tagged AAV VP3 capsid protein and to utilize the 6xHis-tagged VP3 capsid to achieve high-affinity purification of this recombinant AAV.
