Abstract
Avian paramyxoviruses (APMVs) are often carried by wild waterfowl, and the wild waterfowl may play an important role in the maintenance and spread of these viruses. In this study, we investigated APMVs in the population of migratory wild waterfowl from 2015 to 2021 in Korea and analyzed their genetic characteristics. Fourteen viruses were isolated and subsequently identified as APMV-1 (n = 13) and APMV-13 (n = 1). Phylogenetic analysis of the full fusion gene of 13 APMV-1 isolates showed that 10 APMV-1 isolates belonged to the class II sub-genotype I.2, which was epidemiologically linked to viruses from the Eurasian continent, and 3 viruses belonged to class I, which linked to viruses from the USA. The APMV-13 isolates from wild geese in this study were highly homology to the virus isolated from China. Sequence analysis of 14 isolates showed that all isolates had a typical lentogenic motif at the cleavage site. In summary, we identified the wild species likely to be infected with APMV and our data suggest possible intercontinental transmission of APMV by wild waterfowl. Our current study also provides the first evidence for the presence of class I of APMV-1 and APMV-13 in wild waterfowl surveyed in Korea.

Abstract
Newcastle disease (ND) is a notifiable disease affecting chickens and other avian species caused by virulent strains of Avian paramyxovirus type 1 (APMV-1). While outbreaks of ND can have devastating consequences, avirulent strains of APMV-1 generally cause subclinical infections or mild disease. However, viruses can cause different levels of disease in different species and virulence can evolve following cross-species transmission events. This report describes the detection of three cases of avirulent APMV-1 infection in Great Britain (GB). Case 1 emerged from the 'testing to exclude' scheme in chickens in Shropshire while cases 2 and 3 were made directly from notifiable avian disease investigations in chicken broilers in Herefordshire and on premises in Wiltshire containing ducks and mixed species, respectively). Class II/genotype I.1.1 APMV-1 from case 1 shared 99.94% identity to the Queensland V4 strain of APMV-1. Class II/genotype II APMV-1 was detected from case 2 while the class II/genotype I.2 virus from case 3 aligned closely with strains isolated from Anseriformes. Exclusion of ND through rapid detection of avirulent APMV-1 is important where clinical signs caused by avirulent or virulent APMV-1s could be ambiguous. Understanding the diversity of APMV-1s circulating in GB is critical to understanding disease threat from these adaptable viruses.

Abstract
Newcastle disease virus (NDV) infects a wide range of bird species worldwide and is of importance to the poultry industry. Although certain virus genotypes are clearly associated with wild bird species, the role of those species in the movement of viruses and the migratory routes they follow is still unclear. In this study, we performed a phylogenetic analysis of nineteen NDV sequences that were identified among 21,924 samples collected from wild and synanthropic birds from different regions of Ukraine from 2006 to 2015 and compared them with isolates from other continents. In synanthropic birds, NDV strains of genotype II, VI, VII, and XXI of class II were detected. The fusion gene sequences of these strains were similar to strains detected in birds from different geographical regions of Europe and Asia. However, it is noteworthy to mention the isolation of vaccine viruses from synanthropic birds, suggesting the possibility of their role in viral transmission from vaccinated poultry to wild birds, which may lead to the further spreading of vaccine viruses into other regions during wild bird migration. Moreover, here we present the first publicly available complete NDV F gene from a crow (genus Corvus). Additionally, our phylogenetic results indicated a possible connection of Ukrainian NDV isolates with genotype XXI strains circulating in Kazakhstan. Among strains from wild birds, NDVs of genotype 1 of class I and genotype I of class II were detected. The phylogenetic analysis highlighted the possible exchange of these NDV strains between wild waterfowl from the Azov-Black Sea region of Ukraine and waterfowl from different continents, including Europe, Asia, and Africa.

Abstract
Newcastle disease caused by highly pathogenic viruses of avian paramyxovirus serotype-1 (APMV-1) is a highly contagious poultry disease. Although a large-scale epidemic of Newcastle disease had occurred in Japan between the 1950s and the 2000s, there have been no outbreaks anywhere since 2010. In addition, there are no reports of epidemiological surveys of APMV-1 in wild birds in Japan in the last 10 years. We conducted the first epidemiological survey of APMV-1 in the Izumi plain, Kagoshima prefecture of southern Japan from the winter of 2018 to 2022. A total of 15 APMV-1 strains were isolated, and isolation rates from roosting water and duck fecal samples were 2.51% and 0.10%, respectively. These results indicate that the isolation method from environmental water may be useful for efficient surveillance of APMV-1 in wild birds. Furthermore, this is the first report on the success of APMV-1 isolation from environmental water samples. Genetic analysis of the Fusion (F) gene showed that all APMV-1 isolates were closely related to virus strains circulating among waterfowl in Far East Asian countries. All isolates have avirulent motifs in their cleavage site of F genes, all of which were presumed to be low pathogenic viruses in poultry. However, pathogenicity test using embryonated chicken eggs demonstrated that some isolates killed all chicken embryos regardless of viral doses inoculated (102 -106 50% egg infectious dose). These results indicated that APMV-1 strains, which are potentially pathogenic to chickens, are continuously brought into the Izumi plain by migrating wild birds.

Abstract
Newcastle disease virus (NDV), the causative agent that generally causes severe disease in poultry, continues to mutate and has thus evolved into 21 genotypes. We previously isolated a velogenic genotype III NDV JS/7/05/Ch that evolved from the vaccine strain Mukteswar, accompanying by amino acid mutations in Hemagglutinin-Neuraminidase (HN). Here, we sought to investigate the role of the mutant HN protein in NDV virulence. The HN genes of Mukteswar and JS/7/05/Ch were replaced reciprocally via reverse genetics, yielding two recombinant viruses rJS/MHN and rMu/JHN, respectively. rMu/JHN, in which the endogenous HN protein was replaced with the HN protein of JS/7/05/Ch, had a higher intravenous pathogenicity index (IVPI) value in chickens. Moreover, dual aa mutations (A494D and E495K from JS/7/05/Ch-type HN) were introduced into the HN protein of Mukteswar to generate the recombinant virus rMukHN494+495JS. This virus showed an equivalent IVPI value to that of rJS/7/05/Ch (generated from parental JS/7/05/Ch via reverse genetics). In vitro and in vivo assays further showed that A494D and E495K in HN induced antigenic changes, a higher replication level and a more intense inflammatory response. Taken together, these findings indicate that aa mutations in HN are crucial for the virulence of the genotype III Newcastle disease (ND) vaccine strain after intravenous inoculation. Our study further highlights that close surveillance is needed to monitor the genetic variation of ND vaccine strains.

Surveillance of Class I Newcastle Disease Virus at Live Bird Markets in China and Identification of Variants with Increased Virulence and Replication Capacity. J Virol 2022; 96:e0024122.

Abstract
In this study, 232 class I Newcastle disease viruses (NDVs) were identified from multiple bird species at nationwide live bird markets (LBMs) from 2017 to 2019 in China. Phylogenetic analysis indicated that all 232 isolates were clustered into genotype 1.1.2 of class I on the basis of the fusion (F) gene sequences, which were distinct from the genotypes identified in other countries. Most of the isolates (212/232) were shown to have the typical F gene molecular characteristics of class I NDVs, while a few (20/232) contained mutations at the site of the conventional start codon of the F gene, which resulted in open reading frames (ORFs) altered in length. The isolates with ACG, CTA, and ATA mutations showed different levels of increased virulence and replication capacity, suggesting that these viruses may be transitional types during the evolution of class I NDVs from avirulent to virulent. Further evaluation of biological characteristics with recombinant viruses obtained by reverse genetics demonstrated that the ATG located at genomic positions 4523 to 4525 was the authentic start codon in the F gene of class I NDV, and the specific ATA mutations which contributed to the expression of F protein on the surface of infected cells were the key determinants of increased replication capacity and virulence. Interestingly, the mutation at the corresponding site of genotype II LaSota of class II had no effects on the virulence and replication capacity in chickens. Our results suggest that the alteration of virulence and replication capacity caused by specific mutations in the F gene could be a specific characteristic of class I NDVs and indicate the possibility of the emergence of virulent NDVs due to the persistent circulation of class I NDVs. IMPORTANCE The available information on the distribution, genetic diversity, evolution, and biological characteristics of class I Newcastle disease viruses (NDVs) in domestic poultry is currently very limited. Here, identification of class I NDVs at nationwide live bird markets (LBMs) in China was performed and representative isolates were characterized. A widespread distribution of genotype 1.1.2 of class I NDVs was found in multiple bird species at LBMs in China. Though most isolates demonstrated typical molecular characteristics of class I NDVs, a few that contained specific mutations at the site of the conventional start codon of the fusion gene with increased virulence and replication capacity were identified for the first time. Our findings indicate that the virulence of class I NDVs could have evolved, and the widespread transmission and circulation of class I NDVs may represent a potential threat for disease outbreaks in poultry.

Abstract
The risk-based active surveillance for Newcastle disease virus (NDV) was carried out in China from 2011 to 2020. A total of 110,018 swabs were collected from 28 provinces. 2,389 class I NDVs were isolated and identified by RT-PCR and sequencing. The average annual positivity rate of class I NDVs from 2011 to 2020 was 2.17%. In the last 10 years, the positivity rate was highest in 2011 (4.76%), and has since decreased. Most viruses were isolated from chickens, while others were collected from ducks, geese and pigeons, as well as from the environment. The positivity rates for class I NDVs in poultry ranged from 0.55% to 2.40%. The viruses were isolated from 373 sampling sites in 24 provinces, mainly in East, Central, South and Southwest China. The positivity rates of NDVs in wholesale markets (51.58%) and retail markets (42.83%) were much higher than those in poultry farms (7.14%) and slaughterhouses (3.85%). Phylogenetic analyses showed that most isolates belonged to sub-genotype 1.1.2, while only 22 viruses belonged to sub-genotype 1.2, indicating the viruses in sub-genotype 1.1.2 were the predominant strains in China. The F and HN genes of six strains in the two sub-genotypes were sequenced and analyzed. The cleavage sites of F protein in the six viruses were 112ERQER/L117, 112ERQGR/L117 or 112GRQERL117, which were typical of low virulence NDV. Several mutations were identified in the functional domains of F and HN proteins, including fusion peptide, heptad repeat region, transmembrane domains and neutralizing epitopes. This study revealed the distribution, genetic and phylogenetic characteristics of class I NDVs in China, and could help us to better understand the epidemiological context of class I NDVs in China.

Abstract
Newcastle disease (ND), caused by Newcastle disease virus (NDV), is a contagious disease that affects a variety of domestic and wild avian species. Though ND is vaccine-preventable, it is a persistent threat to poultry industry across the globe. The disease represents a leading cause of morbidity and mortality in chickens. To better understand the epidemiology of NDV among commercial and backyard chickens of Odisha, where chicken farming is being prioritized to assist with poverty alleviation, a cross-sectional study was conducted in two distinct seasons during 2018. Choanal swabs (n = 1361) from live birds (commercial layers, broilers, and backyard chicken) and tracheal tissues from dead birds (n = 10) were collected and tested by real-time reverse transcription polymerase chain reaction (RT-PCR) for the presence of matrix (M) and fusion (F) genes of NDV. Risk factors at the flock and individual bird levels (health status, ND vaccination status, geographical zone, management system, and housing) were assessed using multivariable logistic regression analyses. Of the 1371 samples tested, 160 were positive for M gene amplification indicating an overall apparent prevalence of 11.7% (95% CI 10.1–13.5%). Circulation of virulent NDV strains was also evident with apparent prevalence of 8.1% (13/160; 95% CI: 4.8–13.4%). In addition, commercial birds had significantly higher odds (75%) of being infected with NDV as compared to backyard poultry (p = 0.01). This study helps fill a knowledge gap in the prevalence and distribution of NDV in apparently healthy birds in eastern India, and provides a framework for future longitudinal research of NDV risk and mitigation in targeted geographies—a step forward for effective control of ND in Odisha.

Abstract
Although verogenic Newcastle disease viruses (NDVs) generally cause subclinical infection in waterfowls such as ducks, NDVs with high virulence in waterfowl have been sporadically reported.
We previously reported that the NDV d5a20b strain, which is obtained by serial passaging of the velogenic 9a5b strain in domestic ducks, showed increased virulence in ducks (Hidaka
et al., 2021). The d5a20b strain had 11 amino acid substitutions in its P/V, M, F, HN, and L proteins as compared to 9a5b. In the present study, we generated a series of
recombinant (r) NDVs with these amino acid substitutions to identify the molecular basis of virulence of NDV in ducks, and evaluated their influences on virulence and in
vitro viral properties. Each of the single amino acid substitutions in either the F protein I142M or the M protein Q44R contributed to the enhancement of intracerebral and
intranasal pathogenicity in domestic ducks. The cell-cell fusion activity of the virus with F I142M was five times higher than that of the parental r9a5b. The virus with M Q44R rapidly
replicated in duck embryo fibroblasts. Additionally, the rM+F+HN strain, which has the same amino acid sequences as d5a20b in M, F, and HN proteins, showed the highest level of virulence and
replication efficiency among the generated recombinant viruses, nearly comparable to rd5a20b. These results suggest that multiple factors are involved in the high growth ability of NDV in
duck cells, leading to increased virulence in vivo.

Abstract
Newcastle disease virus (NDV) causes Newcastle disease (ND) in poultry. The ND is a highly contagious disease, which is endemic in several countries despite regular vaccination with live or killed vaccines. Studies on NDV in India are mostly targeted toward its detection and characterization from disease outbreaks. A surveillance study was undertaken to determine NDV prevalence throughout the state of Haryana from March 2018 to March 2020 using a stratified sampling scheme. The state was divided into three different zones and a total of 4,001 choanal swab samples were collected from backyard poultry, commercial broilers, and layers. These samples were tested for the M gene of NDV using real-time RT-PCR. Of the 4,001 samples tested, 392 were positive (9.8% apparent prevalence; 95% CI: 8.9–10.8%) for the M gene. Of these 392 M gene positive samples, 35 (8.9%; 95% CI: 6.4–12.3%) were found to be positive based on F gene real-time RT-PCR. Circulation of NDV in commercial and backyard poultry highlights the importance of surveillance studies even in apparently healthy flocks. The information generated in this study should contribute to better understanding of NDV epidemiology in India and may help formulate appropriate disease control strategies for commercial and backyard birds.

Molecular characterization of Toll-like receptor type-3 in mallard duck and its response to Newcastle disease virus infection. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:55786-55795.

Abstract
Toll-like receptors (TLRs), type I transmembrane pattern recognition receptors (PRRs), are composed of the extracellular domain that is implicated in the recognition of microbial products and initiates the innate and adaptive immune response. Previous reports on TLRs in birds showed significant levels of inter- and intraspecific genetic variation. Little is known about the structure and function of the avian immune system, especially waterfowl species. This work aimed to identify and clone Anas platyrhynchos (mallard duck) TLR-3 (dTLR-3) and its expression level following challenge with velogenic Newcastle disease virus (NDV) as a model for waterfowl species. The mallard duck TLR-3 full-length cDNA sequence had been cloned, which consisted of 2457 nucleotides. The translated amino acid sequence showed identity degree as 97% with Muscovy duck, 95% with geese, 89% with helmeted guineafowls, 88% with the chickens TLR-3 gene, 82% with turkey TLR-3, and 79% with zebra finch, while it showed 54% with human one; the analysis data suggested that the new sequence is probably homologous to vertebrates' TLR-3. The predicted protein encoded by the duck dTLR-3 mRNA sequence is composed of 819 amino acids. Analysis of the deduced amino acid sequence indicated that dTLR-3 has typical structural features and contains the main components of proteins in the TLR family. The dTLR-3 expressed in almost all examined tissues of mallard duck following quantitative real-time polymerase chain reaction (qPCR) analysis and using B-actin as a housekeeping gene. To check the functionality of the receptor and its role in viral infection, we evaluate the expression level in different tissues and its changes following NDV infection. The results showed significant (P < 0.05) upregulated in the brain at 24 h (1.84-fold), reached a peak at 48 h (4.82-fold), and recovered to normal levels at 72 h post-infection. These results indicate a complete and functional dTLR-3 that is orthologous to other vertebrate receptors with its potential role in early response against viral infection in mallard duck species.

Abstract
For decades, Newcastle disease (ND) has long been recognized as a frontline viral disease that constrains poultry production throughout Africa. The need to update on the epidemiology of the disease is rife, due to the increasing importance of poultry farming. In addition, poultry farming serves as the top animal food source globally. However, in Africa, the greater population of poultry is reared under traditional and conventional husbandry methods. This hugely impedes the ability of management practices to be correctly embraced in limiting or excluding viral pathogens in the poultry production chain. We conducted this review to consolidate recently published studies in the field and provide an overview of the disease. We reviewed original studies conducted on ND, the current taxonomic classification of the virus, clinical signs of the disease, and laboratory diagnostic methods available for virus detection and typing. This review additionally examined the control methods currently used, including available or circulating vaccines, vaccinations, recent vaccine findings, and the main variants of the virus present in West Africa. More specifically, we present a review of the current status and available information on the disease in Côte d’Ivoire. The lack of up-to-date and relevant information on the current prevalence, socio-economic impact, and ethnoveterinary medicine used against ND is probably the main limitation for appropriate and effective decision-making for better control of this disease in Côte d’Ivoire.

Abstract
Uganda is a Newcastle disease (ND) endemic country where the disease is controlled by vaccination using live LaSota (genotype II) and I2 (genotype I) vaccine strains. Resurgent outbreak episodes call for an urgent need to understand the antigenic diversity of circulating wild Avian Avulavirus serotype-1 (AAvV-1) strains. High mutation rates and the continuous emergence of genetic and antigenic variants that evade immunity make non-segmented RNA viruses difficult to control. Antigenic and functional analysis of the key viral surface proteins is a crucial step in understanding the antigen diversity between vaccine lineages and the endemic wild ND viruses in Uganda and designing ND peptide vaccines. In this study, we used computational analysis, phylogenetic characterization, and structural modeling to detect evolutionary forces affecting the predicted immune-dominant fusion (F) and hemagglutinin-neuraminidase (HN) proteins of AAvV-1 isolates from waterfowl and poultry in Uganda compared with that in LaSota vaccine strain. Our findings indicate that mutational amino acid variations at the F protein in LaSota strain, 25 poultry wild-type and 30 waterfowl wild-type isolates were distributed at regions including the functional domains of B-cell epitopes or N-glycosylation sites, cleavage site, fusion site that account for strain variations. Similarly, conserved regions of HN protein in 25 Ugandan domestic fowl isolates and the representative vaccine strain varied at the flanking regions and potential linear B-cell epitope. The fusion sites, signal peptides, cleavage sites, transmembrane domains, potential B-cell epitopes, and other specific regions of the two protein types in vaccine and wild viruses varied considerably at structure by effective online epitope prediction programs. Cleavage site of the waterfowl isolates had a typical avirulent motif of 111GGRQGR'L117 with the exception of one isolate which showed a virulent motif of 111GGRQKR'F117. All the poultry isolates showed the 111GRRQKR'F117 motif corresponding to virulent strains. Amino acid sequence variations in both HN and F proteins of AAvV-1 isolates from poultry, waterfowl, and vaccine strain were distributed over the length of the proteins with no detectable pattern, but using the experimentally derived 3D structure data revealed key-mapped mutations on the surfaces of the predicted conformational epitopes encompassing the experimental major neutralizing epitopes. The phylogenic tree constructed using the full F gene and partial F gene sequences of the isolates from poultry and waterfowl respectively, showed that Ugandan ND aquatic bird and poultry isolates share some functional amino acids in F sequences yet do remain unique at structure and the B-cell epitopes. Recombination analyses showed that the C-terminus and the rest of the F gene in poultry isolates originated from prevalent velogenic strains. Altogether, these could provide rationale for antigenic diversity in wild ND isolates of Uganda compared with the current ND vaccine strains.

Abstract
Velogenic Newcastle disease virus (NDV) strains, which show high mortality in chickens, generally do not cause severe disease in waterfowl such as ducks. To elucidate the difference in the pathogenic mechanisms of NDV between chickens and ducks, a chicken-derived velogenic strain (9a5b) was passaged in domestic ducks five times in their air sacs, followed by 20 times in their brains. Eventually, 9a5b acquired higher intracerebral and intranasal pathogenicity in ducks. The intracerebral pathogenicity index (ICPI) value increased from 1.10 to 1.88. All one-week-old ducks intranasally inoculated with the passaged virus (d5a20b) died by 5 days post-inoculation, whereas 70% of the ducks inoculated with parental 9a5b survived for 8 days. The d5a20b strain replicated in broader systemic tissues in ducks compared with the 9a5b strain. The velogenic profile of 9a5b in chickens was maintained after passaging in ducks. The d5a20b suppressed IFN-β gene expression in duck embryo fibroblasts and replicated more rapidly than 9a5b. A total of 11 amino acid substitutions were found in the P, V, M, F, HN, and L proteins of d5a20b. These results suggest that chicken-derived velogenic NDVs have the potential to become virulent in both chickens and ducks during circulation in domesticated waterfowl populations. RESEARCH HIGHLIGHTSChicken-derived NDV acquired high pathogenicity in ducks with serial passaging.The passaged NDV showed intracerebral and intranasal pathogenicity in ducks.The passaged NDV efficiently replicated in systemic tissues in ducks.Of 11 amino acid substitutions some or all are likely involved in pathogenicity.

Abstract
Newcastle disease virus (NDV) is distributed worldwide and has caused significant losses to the poultry industry. Almost all virulent NDV strains belong to class II, among which genotype VII is the predominant genotype in China. However, the molecular evolution and phylodynamics of class II genotype VII NDV strains in China remained largely unknown. In this study, we identified 13 virulent NDV including 11 genotype VII strains and 2 genotype IX strains, from clinical samples during 1997 to 2019. Combined NDV sequences submitted to GenBank, we investigate evolution, and transmission dynamics of class II NDVs in China, especially genotype VII strains. Our results revealed that East and South China have the most genotypic diversity of class II NDV, and East China might be the origin of genotype VII NDVs in China. In addition, genotype VII NDVs in China are presumably transmitted by chickens, as the virus was most prevalent in chickens. Furthermore, codon usage analysis revealed that the F genes of genotype VII NDVs have stronger adaptation in chickens, and six amino acids in this gene are found under positive selection via selection model analysis. Collectively, our results revealed the genetic diversity and evolutionary dynamics of genotype VII NDVs in China, providing important insights into the epidemiology of these viruses in China.

Abstract
Newcastle disease virus (NDV), the pathogen of Newcastle disease, has caused significant losses to the poultry industry worldwide. However, owing to its avirulence, class I NDVs have not been studied as much as class II NDVs. We aimed to epidemiologically monitor the spread of class I NDVs in China. We isolated 104 class I NDV strains from poultry in live poultry markets (LPMs) of Guangdong Province, south China, between January 2016 and December 2018. Genetic analysis revealed that all 104 isolates and most of the strains isolated from China were clustered into genotype 1.1.2 of class I NDVs. Bayesian analysis revealed that, although the United States may be the source, east and south China may be the epicentres of class I NDVs in China. In addition, in China, class I NDVs are presumably transmitted by chickens and domestic ducks as the virus is mostly prevalent in these birds. These novel findings demonstrated that class I NDVs are prevalent in south China, and it is important to perform routine surveillance and limit the numbers of different birds in different areas of LPMs to decrease the risk of intra- and interspecies transmission of NDVs.

Abstract
Newcastle disease is a kind of avian infectious disease caused by Newcastle disease virus (NDV). The virulence of NDV is dependent mainly on the fusion (F) protein and hemagglutinin-neuraminidase (HN) protein. The genomes of 2 viruses, NDV-Blackbird and NDV-Dove, are 99.9% similar, while NDV-Blackbird is a velogenic virus, and NDV-Dove is a lentogenic virus. Further analysis revealed that the F proteins of the 2 strains were identical, and only 5 amino acid sites on the HN proteins were inconsistent. Five different HN mutant plasmids were constructed and analyzed in this study. The results showed that the mutation F110L caused a significant increase in fusion-promotion activity caused by an increase in neuraminidase activity. Because of the increase in receptor-binding activity caused by G116R, there was a significant increase in fusion-promotion activity. The mutation G54S resulted in a slight decrease in the fusion-promotion activity caused by a slight decrease in receptor-binding activity. The slight increase in the fusion-promotion activity caused by A469V was associated with a significant increase in neuraminidase activity. Therefore, the amino acids L110 and R116 played a key role in determining the virulence difference between NDV-Blackbird and NDV-Dove, which could lay a foundation for illuminating the virulence differences of NDV strains, as well as the development of attenuated vaccines.

Abstract
Newcastle disease virus (NDV) causes severe economic losses through severe morbidity and mortality and poses a significant threat to the global poultry industry. Significant efforts have been made to develop novel vaccines and therapeutics; however, the interaction of NDV with the host is not yet fully understood. Interferons (IFNs), an integral component of innate immune signaling, act as the first line of defense against invading viruses. Compared with the mammalian repertoire of IFNs, limited information is available on the antiviral potential of IFNs in chickens. Here, we expressed chicken IFN-γ (chIFN-γ) using a baculovirus expression vector system, characterized its antiviral potential against NDV, and determined its antiviral potential. Priming of chicken embryo fibroblasts with chIFN-γ elicited an antiviral environment in primary cells, which was mainly due to interferon-stimulated genes (ISGs). A genome-wide transcriptomics approach was used to elucidate the possible signaling pathways associated with IFN-γ-induced immune responses. RNA-sequencing (RNA-seq) data revealed significant induction of ISG-associated pathways, activated temporal expression of ISGs, antiviral mediators, and transcriptional regulators in a cascade of antiviral responses. Collectively, we found that IFN-γ significantly elicited an antiviral response against NDV infection. These data provide a foundation for chIFN-γ-mediated antiviral responses and underpin functional annotation of these important chIFN-γ-induced antiviral influencers.

Abstract
This chapter describes the development of recombinant oncolytic measles viruses (MeV) that selectively enter and destroy tumor cells. The envelope of MeV is a favorable targeting substrate because receptor attachment and membrane fusion functions are separated on two proteins: the hemagglutinin (H) that binds receptors, and the fusion (F) protein that fuses the viral envelope with the cell membrane. The cell entry process, which depends on receptor recognition and occurs at the plasma membrane at neutral pH, results in the delivery of encapsidated genomes to the cytoplasm, where they replicate. Towards improving cancer specificity of oncolytic MeV, two types of cell entry targeting have been achieved. First, entry has been redirected through cancer-specific cell surface proteins. This was done by displaying specificity domains on H while also ablating binding to its natural receptors. Second, activation of the F protein was made dependent on secreted cancer proteases, while also interfering with F cleavage/activation by a ubiquitous intracellular protease. This chapter describes how entry-targeted MeV are produced: In short, gene cassettes with modified H or F coding regions are generated, and then introduced into the viral genome available on plasmid DNA. Such full-length genome plasmids are transfected in cell lines expressing, stably or transiently, the three viral proteins necessary for genome replication. Infectious centers form among these "rescue" cells, which allow isolation of clonal recombinant viruses. These are amplified, characterized in vitro, and then evaluated for their oncolytic activity in appropriate preclinical animal models.

Abstract
Abstract
Avian avulavirus type 1 (AAvV-1) belongs to the family Paramyxoviridae, genus Avulavirus. Even though belonging to a single serotype, there is great genetic variability between these viruses. On the basis of the available complete fusion (F) gene and whole genome sequences and using the genotype classification system, AAvV-1 viruses are divided in two major groups: class I and class II. Class I viruses are predominantly avirulent viruses and majority of the isolations come from waterfowl and domestic poultry from live bird markets in USA and China although isolations from wild birds are reported globally. In our study we used classical, molecular and phylogenetic tools to characterize an AAvV-1 isolated from a mute swan in Macedonia. Based on the complete F gene sequence, we have concluded that the virus designated as AAvV-1/mute swan/Macedonia/546/2012 (KP123431) belongs to the class I of AAvV-1 with an avirulent cleavage site motif 112ERQER*L117. The virus could not be assigned to any of the four currently existing subgenotypes (1a, 1b, 1c or 1d) of the single genotype 1 of class I viruses. Two distant viruses, isolated from goose in Alaska in 1991 and from goose in Ohio in 1987, shared the highest nucleotide sequence identity of the complete F gene with the isolate in our study: 92.7% and 92.8%, respectively. This is the first report of isolation of class I AAvV-1 in Southeastern Europe. The asymptomatic nature and the underreporting of sequences from the class I viruses impede the understanding of the molecular epidemiology and evolution of this group of viruses.

Abstract
Although Newcastle disease virus (NDV) has a worldwide distribution, some NDV genotypes have more regional geographical ranges within continents. In this study, we isolated a subgenotype XIIb NDV strain, Goose/CH/GD/E115/2017 (E115), from geese in Guangdong province, Southern China, in 2017. Phylogenetic analysis showed that E115 and six other NDVs from geese in China were grouped under subgenotype XIIb and were distinct from subgenotype XIIa, isolated from chickens in South Africa, and subgenotype XIId, isolated from chickens in Vietnam. To better understand the pathogenicity and transmission of the subgenotype XIIb NDVs from geese in Guangdong province, we inoculated chickens and geese with 106 EID50 of the E115 virus. Eight hours after inoculation, three naïve chickens and three naïve geese were co-housed with the infected chickens or geese to assess intraspecific and interspecific horizontal transmission of the E115 virus. The E115 virus induced significant clinical signs without mortality in chickens, while it was not pathogenic to geese. Intraspecific and interspecific horizontal transmission of the E115 virus was observed among chickens and geese via direct contact. Furthermore, although the current vaccines provided complete protection against disease in chickens after challenging them with the E115 virus, the virus could also be transmitted from vaccinated chickens to naïve contact chickens. Collectively, our findings highlight the need for avoiding the mixing of different bird species to reduce cross-species transmission and for surveillance of NDV in waterfowl.

Abstract
BACKGROUND Avian avulavirus (commonly known as avian paramyxovirus-1 or APMV-1) can cause disease of varying severity in both domestic and wild birds. Understanding how viruses move among hosts and geography would be useful for informing prevention and control efforts. A Bayesian statistical framework was employed to estimate the evolutionary history of 1602 complete fusion gene APMV-1 sequences collected from 1970 to 2016 in order to infer viral transmission between avian host orders and diffusion among geographic regions. Ancestral states were estimated with a non-reversible continuous-time Markov chain model, allowing transition rates between discrete states to be calculated. The evolutionary analyses were stratified by APMV-1 classes I (n = 198) and II (n = 1404), and only those sequences collected between 2006 and 2016 were allowed to contribute host and location information to the viral migration networks. RESULTS While the current data was unable to assess impact of host domestication status on APMV-1 diffusion, these analyses supported the sharing of APMV-1 among divergent host taxa. The highest supported transition rate for both classes existed from domestic chickens to Anseriformes (class I:6.18 transitions/year, 95% highest posterior density (HPD) 0.31-20.02, Bayes factor (BF) = 367.2; class II:2.88 transitions/year, 95%HPD 1.9-4.06, BF = 34,582.9). Further, among class II viruses, domestic chickens also acted as a source for Columbiformes (BF = 34,582.9), other Galliformes (BF = 34,582.9), and Psittaciformes (BF = 34,582.9). Columbiformes was also a highly supported source to Anseriformes (BF = 322.0) and domestic chickens (BF = 402.6). Additionally, our results provide support for the diffusion of viruses among continents and regions, but no interhemispheric viral exchange between 2006 and 2016. Among class II viruses, the highest transition rates were estimated from South Asia to the Middle East (1.21 transitions/year; 95%HPD 0.36-2.45; BF = 67,107.8), from Europe to East Asia (1.17 transitions/year; 95%HPD 0.12-2.61; BF = 436.2) and from Europe to Africa (1.06 transitions/year, 95%HPD 0.07-2.51; BF = 169.3). CONCLUSIONS While migration appears to occur infrequently, geographic movement may be important in determining viral diversification and population structure. In contrast, inter-order transmission of APMV-1 may occur readily, but most events are transient with few lineages persisting in novel hosts.

Abstract
In this study, 2 wild-type Newcastle disease viruses (NDVs), designated as CK/GX/65/15 and CK/GX/26/15, were isolated from asymptomatic chickens in Guangxi province, China. They were identified as lentogenic NDV with mean death time (MDT) above 90 and intracerebral pathogenicity index (ICPI) below 0.7. The results of complete genome sequence analysis show that the 2 NDV strains are members of class I genotype 3 with the length 15,198 nt, which followed the "rule of six" and the order 3'-NP-P-M-F-HN-L-5'. In addition, 8 amino acid substitutions were identified in the functional domains of fusion protein (F) of CK/GX/65/15 and 9 in CK/GX/26/15, whose amino acid sequences of F protein cleavage site are 112E-R-Q-E-R-L117. The isolates were found to be apathogenic in specific pathogen free (SPF) chickens and ducks without morbidity or mortality. Furthermore, the protection study shows that isolates can provide the same effective protection against a major NDV virulent strain in China (class II genotype VII) as the commercial vaccine LaSota. Moreover, vaccination with isolates reduced number of chickens shedding virus compared to those vaccinated with LaSota. In conclusion, 2 wild-type NDV strains exhibited fine protection efficacy against genotype VII NDV in poultry and can be considered as candidate vaccines against NDV.

Abstract
INTRODUCTION Previously unknown paramyxovirus strains were isolated from wild birds in 2013-2014 in Kazakhstan and subsequently identified as representatives of the novel Avian avulavirus 20 species. The aims and tasks were molecular genetic characterization of novel avulaviruses and investigation of their phylogenetic relationships. MATERIAL AND METHODS Embryonated chicken eggs were inoculated with cloacal and tracheal swabs from wild birds with subsequent virus isolation. The complete nucleotide sequences of viral genomes were obtained by massive parallel sequencing with subsequent bioinformatics processing. RESULTS By initial infection of chicken embryos with samples from 179 wild birds belonging to the Anatidae, Laridae, Scolopacidae and Charadriidae families, 19 hemagglutinating agents were isolated, and five of them were identified as representatives of new viral species. The study of their sequenced genomes revealed their similarity in size, but there was a significant genetic variability within the species. 2,640 nucleotide substitutions were identified and 273 of them were nonsynonymous, influencing the protein structure of viruses. It was shown that isolates Avian avulavirus 20/black-headed gull/Balkhash/5844/2013 and Avian avulavirus 20 /great black-headed gull/Atyrau/5541/2013 were 86% and 95% respectively identical to the previously described reference strain, indicating a significant evolutionary divergence within species. DISCUSSION The authors suggest the existence of two independent lineages - the Caspian, represented by the reference strain Aktau/5976 and Atyrau/5541, as well as the second, geographically significantly distant Balkhash lineage. CONCLUSION The study confirms the role of the birds of the Laridae family as the main reservoir of Avian avulavirus 20 in the avifauna that plays a key role in maintaining viruses of the genus Avulavirus in the biosphere and is a potential natural source for the emergence of new viral variants. Continuous surveillance of them in the wild is one of the most important tasks in ensuring the safety of the poultry industry.

Abstract
Avian avulaviruses serotype 1 (abbreviated as APMV-1 for the historical name avian paramyxovirus 1) are capable of infecting a wide spectrum of avian species with variable clinical symptoms and outcomes. Ease of transmission has allowed the virus to spread worldwide with varying degrees of virulence depending upon the virus strain and host species. The emergence of new virulent genotypes from global epizootics, and the year-to-year genomic changes in low and high virulence APMV-1 imply that distinct genotypes of APMV-1 are simultaneously evolving at different geographic locations across the globe. This vast genomic diversity may be favoured by large variety of avian species susceptibility to APMV-1 infection, and by the availability of highly mobile wild birds. It has long been considered that waterfowls are not sensitive to APMV-1 and are unable to show any clinical signs, however, outbreaks from the 90's contradict these concepts. The APMV-1 isolates are increasingly reported from the waterfowl. Waterfowl have strong innate immune responses, which minimize the impact of virus infection, however, are unable to prevent the viral shedding. Numerous APMV-1 are carried by domestic waterfowl intermingling with terrestrial poultry. Therefore, commercial ducks and geese should be vaccinated against APMV-1 to minimize the virus shedding and for the prevention the transmission. Genetic diversity within APMV-1 demonstrates the need for continual monitoring of viral evolution and periodic updates of vaccine seed-strains to achieve efficient control and eradication of APMV-1 in waterfowls.

Abstract
Given the global evolutionary dynamics of Newcastle disease viruses (NDVs), it is imperative to continue extensive surveillance, routine monitoring and characterization of isolates originating from natural reservoirs (waterfowls). In this report, we isolated and characterized two virulent NDV strains from clinically healthy mallard (Anas platyrhynchos). Both isolates had a genome of 15,192 nucleotides encoding six genes in an order of 3´-NP-P-M-F-HN-L-5´. The biological characteristics (mean death time: 49.5-50 hr, EID50108.5 ml-1) and presence of a typical cleavage site in the fusion (F) protein (112R-R-Q-K-R↓F117) confirmed the velogenic nature of these isolates. Phylogenetic analysis classified both isolates as members of genotype VII within class-II. Furthermore, based upon the hypervariable region of the F gene (375 nt), isolates showed clustering within sub-genotype VIIi. Similarity index and parallel comparison revealed a higher nucleotide divergence from commonly used vaccine strains; LaSota (21%) and Mukteswar (17%). A comparative residues analysis with representative strains of different genotypes, including vaccine strains, revealed a number of substitutions at important structural and functional domains within the F and hemagglutinin-neuraminidase (HN) proteins. Together, the results highlight consistent evolution among circulating NDVs supporting extensive surveillance of the virus in waterfowl to better elucidate epidemiology, evolutionary relationships and their impacts on commercial and backyard poultry.

Abstract
Newcastle disease, caused by infection with virulent strains of Newcastle disease virus (NDV), poses a risk for the poultry industry. The virulence of NDV is mainly determined by the cleavage site of F protein. Lentogenic NDV can become velogenic after passages in SPF chicken brain and air sac based on some strains isolated from water birds, because the proportion of virulent-related strains gradually increases. In contrast, this proportion remains unchanged if NDV is passaged via 10-day-old SPF chicken embryos. This information suggests that environmental conditions rather than mutation affect NDV fitness in quasispecies. However, it is unknown how the environment selects virulent-related strains from a viral population. In this study, velogenic and lentogenic NDV marked by green or red fluorescence were used to establish persistent infection (PI) in BHK-21 cells. Monitoring viruses by different methods, we found that, without competition, persistently infected cells harbored lentogenic and velogenic NDV strains similarly in terms of viral release, viral spread and the period of persistent viral infection. In contrast, under competitive co-infection, velogenic NDV became dominant in quasispecies from the fifth passage of PI cells, which resulted in the progressive disappearance of the lentogenic NDV strain. This domination was concomitant with a short-term reduction in the superinfection exclusion and supernatant interference in PI cells resulting in a velogenic virus rebound. We concluded that virulent-related F protein cleavage site facilitates the spread and replication of NDV in conditions under which cells do not secret trypsin-like proteases and do not inhibit free virus infection, resulting in a gradual increase in virulent strains in quasispecies with the number of passages.

Spillover of Newcastle disease viruses from poultry to wild birds in Guangdong province, southern China. INFECTION GENETICS AND EVOLUTION 2017; 55:199-204.

Abstract
Despite intensive vaccination programs in many countries, including China, Newcastle disease has been reported sporadically and is still a significant threat to the poultry industry in China. Newcastle disease virus (NDV) is infectious for at least 250 bird species, but the role of wild birds in virus epidemiology remains largely unknown. Fourteen NDV isolates were obtained from 2040 samples collected from wild birds or the environment in Guangdong province, southern China, from 2013 to 2015. The isolation rate was the highest in the period of wintering and lowest during the periods of spring migration, nesting, and postnesting. A maximum clade credibility phylogenetic analysis revealed that at least four genotypes circulate in southern China: three class II genotypes (II, VI, and IX) and one class I (1b). We also demonstrated that most isolates from wild birds were highly similar to isolates from poultry, and two isolates were linked to viruses from wild birds in northern China. These data suggested that wild birds could disseminate NDV and poultry-derived viruses may spillover to wild birds. Accordingly, vaccine development and poultry management strategies should be considered to prevent future NDV outbreaks, particularly given the strength of the poultry industry in developing countries, such as China.

Abstract
In this study, we investigated the pathogenesis of Newcastle disease virus (NDV) in the chicken kidney. Twenty-six 32-day-old specific pathogen-free chickens were intranasally inoculated with the 9a5b NDV mutant isolate. Kidney tissue samples, collected at 6 and 12 hours postinoculation (hpi) and 1, 2, 3, 5, and 10 days postinoculation (dpi), were analyzed by histopathology, immunohistochemistry (IHC), reverse transcription polymerase chain reaction (RT-PCR), and virus titration. Histopathologically, tubulointerstitial nephritis was detected in the renal cortex and predominantly in the medulla. Nephrotropism of 9a5b NDV was confirmed by IHC, RT-PCR, and virus isolation. Massive degenerative changes and infiltration of CD3-immunopositive cells accompanied replication of the 9a5b NDV isolate in chicken kidneys. In conclusion, pathological changes that were caused by NDV in chicken kidneys were similar to those caused by avian influenza virus, infectious bronchitis virus, and avian nephritis virus, and this highlights the importance of including NDV in the differential diagnosis of kidney disease in chickens.

Abstract
One class I Newcastle disease virus (NDV), designated as duck/Guangxi/1261/2015 (GX1261), was isolated from asymptomatic ducks in live bird markets (LBM) from southern China during the national active surveillance for NDVs in 2015. The complete genome length of GX1261 isolate was 15,198 nucleotides with the gene order of 3'-NP-P-M-F-HN-L-5'. The motif at the cleavage site of F protein was 112ERQER/L117, which was typical of low virulence NDV. Several mutations were identified in the functional domains of F and HN proteins, including fusion peptide, heptad repeat region, transmembrane domains and neutralizing epitopes. Phylogenetic analysis based on the complete F gene revealed that the isolate was clustered into sub-genotype 1c in class I, and showed a high level of similarity with the strains isolated from waterfowl in the United States of America. This is the first report of this kind of virus in the mainland of China. These results demonstrated that GX1261-like viruses might exist in asymptomatic waterfowl, and remain undetected or unidentified. Thus, more investigation needs to be done in order to identify the source of the virus. This study revealed the genetic and phylogenetic characteristics of GX1261 isolate and could help us to better understand the epidemiological context of class I NDV in China.

Abstract
Newcastle disease virus (NDV) encodes a highly phosphorylated P protein; however, the phosphorylation sites have not been identified, and the relationship between phosphorylation and protein function is still unclear. In this study, we bioinformatically predicted 26 amino acid residues in the P protein as potential phosphorylation sites. Furthermore, we treated infected cells with kinase inhibitors to investigate NDV propagation and found that protein kinase C (PKC) is involved in the NDV life cycle and that PKC-activated phosphorylation functions in NDV replication. Using an NDV minigenome assay, we found that expression of a reporter protein decreased when the minigenome system contained P mutants lacking T44, S48, T271, S373 and especially T111. The phosphorylation status of S48, T111, S125 and T271 was determined by Phos-tag SDS-PAGE analysis. Coimmunoprecipitation assays showed that the binding activity of NP and the P-T111A mutant was stronger than that of NP and the wild-type P, suggesting that P-T111 is involved in NP-P interaction. This study sheds light on the mechanism by which P protein phosphorylation affects NDV replication and transcription.

Abstract
Background Chickens and ducks are major hosts of Newcastle disease virus (NDV) with distinct responses to infection. However, whereas ducks are generally asymptomatic or exhibit only mild symptoms following NDV infection and are thus regarded as potential long-term reservoirs of the virus, chickens exhibit severe clinical lesions, transient infections and even death due to NDV infection. These differences may in part result from the host innate immune response to NDV infection. Methods To better understand the host innate immune response to NDV infection in avian species, by using the quantitative real-time polymerase chain reaction method we examined the messenger RNA expression levels of immune-related genes in chicken embryonic fibroblasts (CEFs) and duck embryonic fibroblasts (DEFs) when infected with NDV of different pathogenicities. Results Gene expression profiles showed that the expression of IL-1beta, TNF-α-like factor (LITAF) and interferon (IFN)-beta was upregulated in both CEFs and DEFs infected with SS-10 and NH-10 viruses or treated with polyinosinic:polycytidylic acid [poly(I:C)], as well as that expression levels were greater in CEFs than in DEFs. The expression of TLR3, TLR7, IL-6, IFN-alpha, IFN-gamma, MHC-I and MHC-II, except for IL-8, were also greater in CEFs than in DEFs in response to infection to both viruses or treatment with poly(I:C). However, unlike moderate virulent NH-10, highly virulent SS-10 induced greater pattern recognition receptors and cytokines, except for IFNs, in CEFs and DEFs. Conclusion Results show distinct expression patterns of cytokines, Toll-like receptors and IFNs associated with inflammatory immune responses to NDV between species and by virulence.

Kang Y, Xiang B, Yuan R, Zhao X, Feng M, Gao P, Li Y, Li Y, Ning Z, Ren T. Phylogenetic and Pathotypic Characterization of Newcastle Disease Viruses Circulating in South China and Transmission in Different Birds. Front Microbiol 2016; 7:119. [PMID: 26903997 PMCID: PMC4746259 DOI: 10.3389/fmicb.2016.00119] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2015] [Accepted: 01/22/2016] [Indexed: 12/14/2022] Open
Abstract
Although Newcastle disease virus (NDV) with high pathogenicity has frequently been isolated in poultry in China since 1948, the mode of its transmission among avian species remains largely unknown. Given that various wild bird species have been implicated as sources of transmission, in this study we genotypically and pathotypically characterized 23 NDV isolates collected from chickens, ducks, and pigeons in live bird markets (LBMs) in South China as part of an H7N9 surveillance program during December 2013–February 2014. To simulate the natural transmission of different kinds of animals in LBMs, we selected three representative NDVs—namely, GM, YF18, and GZ289—isolated from different birds to evaluate the pathogenicity and transmission of the indicated viruses in chickens, ducks, and pigeons. Furthermore, to investigate the replication and shedding of NDV in poultry, we inoculated the chickens, ducks, and pigeons with 106 EID50 of each virus via intraocular and intranasal routes. Eight hour after infection, the naïve contact groups were housed with those inoculated with each of the viruses as a means to monitor contact transmission. Our results indicated that genetically diverse viruses circulate in LBMs in South China's Guangdong Province and that NDV from different birds have different tissue tropisms and host ranges when transmitted in different birds. We therefore propose the continuous epidemiological surveillance of LBMs to support the prevention of the spread of these viruses in different birds, especially chickens, and highlight the need for studies of the virus–host relationship.

Abstract
Newcastle disease virus (NDV) V protein is considered as an effector for IFN antagonism, however, the mechanism remains unknown. In this study, the expression of STAT1 and phospho-STAT1 in cells infected with NDV or transfected with V protein-expressing plasmids were analyzed. Our results showed that NDV V protein targets phospho-STAT1 reduction in the cells depends on the stimulation of IFN-α. In addition, a V-deficient genotype VII recombinant NDV strain rZJ1-VS was constructed using reverse genetic technique to confirm the results. The rZJ1-VS lost the ability to reduce phospho-STAT1 and induced higher expression of IFN-responsive genes in infected cells. Furthermore, treatment with an ubiquitin E1 inhibitor PYR-41 demonstrated that phospho-STAT1 reduction was caused by degradation, but not de-phosphorylation. We conclude that NDV V protein targets phospho-STAT1 degradation to block IFN-α signaling, which adds novel knowledge to the strategies used by paramyxoviruses to evade IFN.

Circulation of avian paramyxoviruses in wild birds of Kazakhstan in 2002-2013. Virol J 2016; 13:23. [PMID: 26846092 PMCID: PMC4743248 DOI: 10.1186/s12985-016-0476-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Accepted: 01/25/2016] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Screening wild birds for avian paramyxoviruses is of increasing importance. 6913 samples of tracheal and cloacal swabs were collected during 2002-2013 and tested to study the prevalence of APMVs in wild avifauna of Kazakhstan. As a result, 45 isolates were obtained during this period and their ecological niches and genetic relationships were defined. METHODS Tracheal and cloacal samples from wild birds were collected using sterile swabs placed in viral transport medium and kept in liquid nitrogen until delivery to the laboratory. Samples were inoculated into 10-day-old embryonated chicken eggs and reverse transcription PCR (RT-PCR) assays were performed via a one-step protocol. The PCR products were sequenced and phylogenetic trees were constructed using the 'Neighbour Joining' method. RESULTS Six thousand nine hundred thirteen samples from 183 bird species were investigated and 45 isolates belonging to four different serotypes APMV-1, APMV-4, APMV-6 and APMV-8 were identified. All APMVs were isolated predominantly from birds belonging to Anatidae family (ducks and geese) and only one APMV-4 isolate was obtained from shorebird (Curlew) on the Caspian seashore. Genetic studies showed that the recovered APMV-1 strains had highest homology with European isolates. APMV-4 strains isolated in 2003, and APMV-6 and APMV-8 isolated in 2013 were 99 % identical to isolates from Far East. CONCLUSION This is the first reported characterization of avian paramyxoviruses from wild birds isolated in Kazakhstan. These data confirm the wide distribution of APMV-1, APMV-4 and APMV-6 in the Asian subcontinent. The obtained data contribute to the accumulation of knowledge on the genetic diversity and prevalence of APMVs in wild bird populations.

High Genetic Diversity of Newcastle Disease Virus in Wild and Domestic Birds in Northeastern China from 2013 to 2015 Reveals Potential Epidemic Trends. Appl Environ Microbiol 2015; 82:1530-1536. [PMID: 26712543 DOI: 10.1128/aem.03402-15] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Accepted: 12/16/2015] [Indexed: 11/20/2022] Open
Abstract
Newcastle disease (ND), caused by the virulent Newcastle disease virus (NDV), is one of the most important viral diseases of birds globally, but little is currently known regarding enzootic trends of NDV in northeastern China, especially for class I viruses. Thus, we performed a surveillance study for NDV in northeastern China from 2013 to 2015. A total 755 samples from wild and domestic birds in wetlands and live bird markets (LBMs) were collected, and 10 isolates of NDV were identified. Genetic and phylogenetic analyses showed that five isolates from LBMs belong to class I subgenotype 1b, two (one from wild birds and one from LBMs) belong to the vaccine-like class II genotype II, and three (all from wild birds) belong to class II subgenotype Ib. Interestingly, the five class I isolates had epidemiological connections with viruses from southern, eastern, and southeastern China. Our findings, together with recent prevalence trends of class I and virulent class II NDV in China, suggest possible virus transmission between wild and domestic birds and the potential for an NDV epidemic in the future.

Evolution of Newcastle Disease Virus Quasispecies Diversity and Enhanced Virulence after Passage through Chicken Air Sacs. J Virol 2015; 90:2052-63.

Abstract
UNLABELLED It has been reported that lentogenic Newcastle disease virus (NDV) isolates have the potential to become velogenic after their transmission and circulation in chickens, but the underlying mechanism is unclear. In this study, a highly velogenic NDV variant, JS10-A10, was generated from the duck-origin lentogenic isolate JS10 through 10 consecutive passages in chicken air sacs. The velogenic properties of this selected variant were determined using mean death time (MDT) assays, intracerebral pathogenicity index (ICPI), the intravenous pathogenicity index (IVPI), histopathology, and the analysis of host tissue tropism. In contrast, JS10 remained lentogenic after 20 serial passages in chicken eggs (JS10-E20). The JS10, JS10-A10, and JS10-E20 genomes were sequenced and found to be nearly identical, suggesting that both JS10-A10 and JS10-E20 were directly generated from JS10. To investigate the mechanism for virulence enhancement, the partial genome covering the F0 cleavage site of JS10 and its variants were analyzed using ultradeep pyrosequencing (UDPS) and the proportions of virulence-related genomes in the quasispecies were calculated. Velogenic NDV genomes accumulated as a function of JS10 passaging through chicken air sacs. Our data suggest that lentogenic NDV strains circulating among poultry might be a risk factor to future potential velogenic NDV outbreaks in chickens. IMPORTANCE An avirulent isolate, JS10, was passaged through chicken air sacs and embryos, and the pathogenicity of the variants was assessed. A virulent variant, JS10-A10, was generated from consecutive passage in air sacs. We developed a deep-sequencing approach to detect low-frequency viral variants across the NDV genome. We observed that virulence enhancement of JS10 was due to the selective accumulation of velogenic quasispecies and the concomitant disappearance of lentogenic quasispecies. Our results suggest that because it is difficult to avoid contact between natural waterfowl reservoirs and sensitive poultry operations, circulating lentogenic NDV strains may represent a potential reservoir for emergent velogenic NDV strains that could cause outbreaks in chickens.

Abstract
The aim of this study was to investigate the effect of Newcastle disease virus (NDV) on the chicken pancreas. A virulent 9a5b mutant NDV isolate was inoculated intranasally into 32-day-old specific pathogen-free white Leghorn chickens. The pancreas was examined grossly and fixed for histopathological, immunohistochemical and electron microscopical investigations. Inflammatory changes were observed in the peripancreatic tissue at the early stage of infection (12 h post infection) and became more prevalent towards the end of the experiment. Multifocal areas of necrotizing inflammation were detected in the exocrine portion of the pancreas by 5 days post infection (dpi) and became more severe at 10 dpi. The endocrine islets were generally preserved, but slight degenerative changes were observed at 10 dpi. Immunohistochemically, NDV-nucleoprotein (NDV-NP) signals were detected in the peripancreatic tissues (associated with macrophages and other lymphoid cells) by 1 dpi. In the exocrine portion of the pancreas, NDV-NP signals were detected at 5 dpi and increased in intensity and distribution by 10 dpi. NDV particles were confirmed in the cytoplasm of exocrine acinar cells by transmission electron microscopy. CD3-positive cells were observed in the peripancreatic tissues earlier than in the pancreatic tissue. Moreover, in comparison with control chickens, insulin immunoexpression was unchanged, except on the last day of the experiment, when it was slightly reduced. The 9a5b NDV infection induced an inflammatory reaction and viral replication in the peripancreatic tissues earlier than in the pancreatic tissue. Furthermore, necrosis affected mainly the exocrine portion of the pancreas, while the endocrine portion was generally unaffected.

Abstract
An avian paramyxovirus (APMV) isolated from goose feces (APMV/Shimane67) was
biologically, serologically and genetically characterized. APMV/Shimane67 showed typical
paramyxovirus morphology on electron microscopy. On hemagglutination inhibition test,
antiserum against APMV/Shimane67 revealed low reactivity with other APMV serotypes and
vice versa. The fusion (F) protein gene of APMV/Shimane67 contained
1,638 nucleotides in a single open reading frame encoding a protein of 545 amino acids.
The cleavage site of F protein contained a pair of single basic amino
acid (VRENR/L). The nucleotide and deduced amino acid sequences of the F gene
of APMV/Shimane67 had relatively low identities (42.9–62.7% and 28.9–67.3%, respectively)
with those of other APMVs. Phylogenetic analysis showed that APMV/Shimane67 was related to
NDV, APMV-9 and APMV-12, but was distinct from those APMV serotypes. These results suggest
that APMV/Shimane67 is a new APMV serotype, APMV-13.

Abstract
Newcastle disease virus (NDV) causes a highly contagious viral disease in poultry and wild birds, and it can cause significant economic loss worldwide. Eight viral strains were isolated by inoculating embryonated chicken eggs from the Poyang Lake region of China with swab samples. All eight of the NDV isolates were identified as class I genotype 3 strains, but they diverged notablely from class II viruses. Further analysis revealed that all eight NDV isolates were lentogenic strains containing the (112)ERQER↓L(117) motif at the F protein cleavage site. The strains were highly identical and were more species specific (chicken and waterfowl) than site specific (Nanchang and Duchang regions). The close phylogenetic proximity of these isolates indicates that viral transmission may happen between poultry and wild birds. Our study demonstrates that lentogenic class I NDVs exist in clinically healthy wild waterfowl and poultry within the Poyang Lake region. Active surveillance of these viruses to determine their evolution and origin is one of the most realistic strategies for preventing and controlling NDV outbreaks.

Abstract
To further understand the epidemiology of avian paramyxovirus serotype-1 (APMV-1) in
migratory waterfowls in Japan, we conducted the surveillance of this virus from feces
derived from the migratory waterfowls collected in 41 Japanese prefectures between October
2011 and March 2013. Six APMV-1 viruses were isolated from total 661 samples. All isolates
were identified as the avirulent (lentogenic) type on the basis of intracerebral
pathogenicity tests. Genetic analysis showed that these viruses possessed the deduced
amino acid sequence of 112GKQGR-L117 or
112ERQER-L117 at the cleavage site of the F0 protein, which was
identical to the motif in the avirulent type. Phylogenetic analysis based on the partial
fusion protein gene classified these APMV-1 isolates into 2 major genetic groups. Four
isolates were classified as class II genotype I, and they were genetically closely related
to strains isolated in Asian countries, including Japan. In contrast, two isolates were
classified as class I, and they were genetically closely related to strains mainly
isolated in the U.S.A.

Abstract
Background The strains of Newcastle disease virus (NDV) can be divided into two distinct clades: class I and class II. At present, limited molecular epidemiological data are available for the class I virus at live bird markets (LBMs). Knowing the genomic and antigenic characteristics of class I NDVs might provide important insights into the evolution dynamics of these viruses. In this study class I NDVs isolated from LBMs in Eastern China between 2008 and 2012 were characterized. Results We characterized 34 class I NDVs genetically and 15 of the 34 NDVs pathologically which originated from geese, chickens and ducks at live bird markets. Based on the older classification system, twelve of fourteen strains isolated from 2008 to 2010 belonged to sub-genotype 3b. However, the rest 22 strains formed a separate novel cluster in genotype 3, which was designated as sub-genotype 3c. When based on the new classification system, sub-genotype 3b was classified into sub-genotype 1a and the sub-genotype 3c was classified into sub-genotype 1b. Over 62% (21/34) of the viruses were chicken-origin and only 13 isolates were waterfowl-origin. The Cross-neutralization reactions between CK/JS/05/11, CK/JS/06/12 and the vaccine strain LaSota showed significant antigenic differences between them. Conclusions Currently, sub-genotype 3c (or 1b) NDVs are the most frequently isolated classI strains at LBMs in Eastern China., and the class I NDVs has transferred from waterfowls to chickens and circulated in chicken flocks extensively.

Detection of Newcastle disease virus minor genetic variants by modified single-stranded conformational polymorphism analysis. BIOMED RESEARCH INTERNATIONAL 2014; 2014:632347. [PMID: 24812625 PMCID: PMC4000945 DOI: 10.1155/2014/632347] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2013] [Accepted: 03/12/2014] [Indexed: 12/12/2022]
Abstract
Newcastle disease and Avian Influenza are considered to be the most dangerous fowl diseases which may cause huge economic losses. Newcastle disease is caused by the enveloped, and single-stranded RNA virus (NDV, APMV-1; belonging to Paramyxoviridae family), which can be further divided into sixteen different genotypes grouped into five pathotypes according to their pathogenicity. It has been reported that low pathogenic virus can greatly increase its pathogenicity even during a single passage. Additionally, due to the widespread use of live vaccines, a mixture of two or more different viruses in one sample can be detected. Hence, there is a great need for establishment of fast, inexpensive, sensitive, and relatively simple diagnostic method for multistrain and quasispecies detection of NDV infection. In this paper we describe a diagnostic method based on RT-PCR followed by a modified version of single-stranded conformational polymorphism analysis using short DNA fragments of gene encoding viral F protein. The method allows for rapid diagnosis of genetic variant emerging from previously stable population which may prevent the spread of the pathogenic viral variant.

Abstract
Relatively little is known about the distribution of avian paramyxoviruses
(APMVs) among wild birds in Japan. Surveillance of APMV in migratory waterfowl was
conducted in the San-in region of western Japan during winters of 2006 to 2012. A total of
16 avian paramyxoviruses consisting of 3 lentogenic Newcastle disease viruses (NDVs), 12
APMV-4 and 1 APMV-8 were isolated from 1,967 wild-bird fecal samples. The results show
that NDV and APMV-4 are relatively widely distributed among wild waterfowl that migrate to
Japan from northern regions. Phylogenetic analysis revealed that there was no genetic
relationship between the isolates from wild birds and domestic poultry in Japan. However,
surveillance of APMVs in wild waterfowl needs to be conducted due to the pathogenic
potential of these isolates in domestic poultry.

Abstract
Newcastle disease, induced by a type 1 Avian Paramyxovirus (APMV-1), is one of the most serious poultry diseases. APMV-1 are divided into two classes based on genetic analysis: class II strains have been recovered from wild or domestic birds and include virulent and avirulent isolates whereas class I strains have been mainly isolated from wild birds and are avirulent. Within class I, a new proposed genotype has recently been reported. The only full genome strain of this group is presently characterised from the point of view of codon usage with reference to class I and class II specificities. Class-specific residues were identified on HN and F proteins that are the two major proteins involved in cell attachment and pathogenicity. Comparison of protein patterns and codon usage for this newly identified APMV-1 strain indicates it is similar to class I viruses but contains a few characteristics close to the viruses of class II. Transmission of viruses from this recently identified divergent group from wild birds to domestic birds could have a major impact on the domestic poultry industry.
