Abstract
Here, we performed molecular and pathogenic characterization of a Newcastle disease virus (NDV) isolate from pigeons in Bangladesh. Molecular phylogenetic analysis based on the complete fusion gene sequences classified the three study isolates into genotype XXI (sub-genotype XXI.1.2) together with recent NDV isolates obtained from pigeons in Pakistan (2014-2018). The Bayesian Markov Chain Monte Carlo analysis revealed that the ancestor of Bangladeshi pigeon NDVs and the viruses from sub-genotype XXI.1.2 existed in the late 1990s. Pathogenicity testing using mean embryo death time pathotyped the viruses as mesogenic, while all isolates carried multiple basic amino acid residues at the fusion protein cleavage site. Experimental infection of chickens and pigeons revealed no or minimum clinical signs in chickens, while a relatively high morbidity (70%) and mortality (60%) were observed in pigeons. The infected pigeons showed extensive and systemic lesions including hemorrhagic and/or vascular changes in the conjunctiva, respiratory and digestive system and brain, and atrophy in the spleen, while only mild congestion in the lungs was noticed in the inoculated chickens. Histologically, consolidation in the lungs with collapsed alveoli and edema around the blood vessels, hemorrhages in the trachea, severe hemorrhages and congestion, focal aggregation of mononuclear cells, and single hepatocellular necrosis in the liver, severe congestion, multifocal tubular degeneration, and necrosis, as well as mononuclear cell infiltration in the renal parenchyma, encephalomalacia with severe neuronal necrosis with neuronophagia were noticed in the brain in infected pigeons. In contrast, only slight congestion was found in lungs of the infected chickens. qRT-PCR revealed the replication of the virus in both pigeons and chickens; however, higher viral RNA loads were observed in oropharyngeal and cloacal swabs, respiratory tissues, and spleen of infected pigeons than the chickens. In conclusion, genotype XXI.1.2 NDVs are circulating in the pigeon population of Bangladesh since 1990s, produce high mortality in pigeons with pneumonia, hepatocellular necrosis, renal tubular degeneration, and neuronal necrosis in pigeons, and may infect chickens without overt signs of clinical disease and are likely to shed viruses via the oral or cloacal routes.

Viruses 2021; 13:v13081520. [PMID: 34452385 PMCID: PMC8402815 DOI: 10.3390/v13081520] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/16/2021] [Accepted: 07/29/2021] [Indexed: 01/23/2023] Open
Abstract
Newcastle disease virus (NDV) is a significant pathogen of poultry; however, variants also affect other species, including pigeons. While NDV is endemic in Bangladesh, and poultry isolates have been recently characterized, information about viruses infecting pigeons is limited. Worldwide, pigeon-derived isolates are commonly of low to moderate virulence for chickens. Here, we studied a pigeon-derived NDV isolated in Bangladesh in 2010. To molecularly characterize the isolate, we sequenced its complete fusion gene and performed a comprehensive phylogenetic analysis. We further studied the biological properties of the virus by estimating mean death time (MDT) and by experimentally infecting 5-week-old naïve Sonali chickens. The studied virus clustered in sub-genotype XXI.1.2 with NDV from pigeons from Pakistan isolated during 2014–2018. Deduced amino acid sequence analysis showed a polybasic fusion protein cleavage site motif, typical for virulent NDV. The performed in vivo pathogenicity testing showed a MDT of 40.8 h, and along with previously established intracerebral pathogenicity index of 1.51, these indicated a velogenic pathotype for chickens, which is not typical for pigeon-derived viruses. The experimental infection of chickens resulted in marked neurological signs and high mortality starting at 7 days post infection (dpi). Mild congestion in the thymus and necrosis in the spleen were observed at an advanced stage of infection. Microscopically, lymphoid depletion in the thymus, spleen, and bursa of Fabricius were found at 5 dpi, which progressed to severe in the following days. Mild to moderate proliferation of glial cells was noticed in the brain starting at 2 dpi, which gradually progressed with time, leading to focal nodular aggregation. This study reports the velogenic nature for domestic chickens of a pigeon-derived NDV isolate of sub-genotype XXI.1.2. Our findings show that not all pigeon-derived viruses are of low virulence for chickens and highlight the importance of biologically evaluating the pathogenicity of NDV isolated from pigeons.

Abstract
The characteristics and risk factors of pigeon paramyxovirus type 1 (PPMV-1) infection in humans are poorly known. We performed virological, pathological, and epidemiological analyses of a Dutch case, and compared the results with those of a US case. Both infections occurred in transplant patients under immunosuppressive therapy and caused fatal respiratory failure. Both virus isolates clustered with PPMV-1, which has pigeons and doves as reservoir. Experimentally inoculated pigeons became infected and transmitted the virus to naive pigeons. Both patients were likely infected by contact with infected pigeons or doves. Given the large populations of feral pigeons with PPMV-1 infection in cities, increasing urbanization, and a higher proportion of immunocompromised individuals, the risk of severe human PPMV-1 infections may increase. We recommend testing for avian paramyxovirus type 1, including PPMV-1, in respiratory disease cases where common respiratory pathogens cannot be identified.

Phylogenetic assessment reveals continuous evolution and circulation of pigeon-derived virulent avian avulaviruses 1 in Eastern Europe, Asia, and Africa. BMC Vet Res 2017; 13:291.

Abstract
Background The remarkable diversity and mobility of Newcastle disease viruses (NDV) includes virulent viruses of genotype VI. These viruses are often referred to as pigeon paramyxoviruses 1 because they are normally isolated and cause clinical disease in birds from the Columbidae family. Genotype VI viruses occasionally infect, and may also cause clinical disease in poultry. Thus, the evolution, current spread and detection of these viruses are relevant to avian health. Results Here, we describe the isolation and genomic characterization of six Egyptian (2015), four Pakistani (2015), and two Ukrainian (2007, 2013) recent pigeon-derived NDV isolates of sub-genotype VIg. These viruses are closely related to isolates from Kazakhstan, Nigeria and Russia. In addition, eight genetically related NDV isolates from Pakistan (2014–2016) that define a new sub-genotype (VIm) are described. All of these viruses, and the ancestral Bulgarian (n = 2) and South Korean (n = 2) viruses described here, have predicted virulent cleavage sites of the fusion protein, and those selected for further characterization have intracerebral pathogenicity index assay values characteristic of NDV of genotype VI (1.31 to 1.48). A validated matrix gene real-time RT-PCR (rRT-PCR) NDV test detect all tested isolates. However, the validated rRT-PCR test that is normally used to identify the virulent fusion gene fails to detect the Egyptian and Ukrainian viruses due to mismatches in primers and probe. A new rapid rRT-PCR test to determine the presence of virulent cleavage sites for viruses from sub-genotypes VIg was developed and evaluated on these and other viruses. Conclusions We describe the almost simultaneous circulation and continuous evolution of genotype VI Newcastle disease viruses in distant locations, suggesting epidemiological connections among three continents. As pigeons are not migratory, this study suggests the need to understand the possible role of human activity in the dispersal of these viruses. Complete genomic characterization identified previously unrecognized genetic diversity that contributes to diagnostic failure and will facilitate future evolutionary studies. These results highlight the importance of conducting active surveillance on pigeons worldwide and the need to update existent rapid diagnostic protocols to detect emerging viral variants and help manage the disease in affected regions.

Pigeon paramyxovirus type 1 variants with polybasic F protein cleavage site but strikingly different pathogenicity. Virus Genes 2014; 49:502-6. [PMID: 25228150 DOI: 10.1007/s11262-014-1111-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2014] [Accepted: 08/22/2014] [Indexed: 10/24/2022]
Abstract
Newcastle disease viruses (NDV) isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) are mostly of mesogenic pathotype and characterized by a polybasic amino acid sequence motif at the fusion protein (F) cleavage site. This feature also applies to isolate R75/98 from Germany. Its genome consists of 15,192 nucleotides and it specifies an intracerebral pathogenicity index (ICPI) of 1.1, as is typical for mesogenic NDV. Recombinant R75/98 (rR75/98) derived by reverse genetics also possesses a polybasic F protein cleavage site but exhibits ICPI of 0.28, indicating a lentogenic virus. While ten virus passages of rR75/98 on embryonated chicken eggs did not result in any alteration of virus characteristics, virus which had been re-isolated from the brain of an intracerebrally inoculated chicken showed an increase in virulence, characterized by an ICPI of 0.93. Comparison of whole genome sequences of rR75/98 and re-isolated rR75/98 (RrR75/98) demonstrated only two amino acid differences, one in the F protein (N472 K) and one in the polymerase protein (K2168R). This result indicates that only very few amino acid alterations are sufficient to modulate virus virulence in the presence of a polybasic amino acid sequence at the proteolytic F protein cleavage site.

Abstract
Genotype VI-paramyxovirus (GVI-PMV1) is a major cause of epidemic Newcastle-like disease in Columbiformes. This genotype of avian paramyxovirus type 1 has diversified rapidly since its introduction into the US in 1982 resulting in two extant lineages, which have different population growth properties. Although some GVI-PMV1s replicate poorly in chickens, it is possible that variants with different replicative or pathogenic potential in chickens exist among the genetically-diverse GVI-PMV1s strains. To determine if variants of Columbiform GVI-PMV1 with different phylogenetic affiliations have distinct phenotypic properties in chickens, we investigated the replicative properties of 10 naturally circulating pigeon-derived isolates representing four subgroups of GVI-PMV1 in primary chicken lung epithelial cells and in chicken embryos. Our data demonstrate that GVI-PMV1 variants have different infection phenotypes in their chicken source host and that properties reflect subgroup affiliation. These subgroup replicative properties are consistent with observed dynamics of viral population growth.

Abstract
The pathogenicity and genetic characterizations of six Newcastle disease virus (NDV) isolates obtained from chicken farms in six different regions in Iran were carried out using conventional and molecular techniques. Based on the pathogenicity indices (MDT, ICPI, and IVPI), all of these isolates were found to be velogenic (highly virulent) strains. A sequence analysis of the full-length mRNA encoding the fusion glycoprotein precursor (F0) of the NDV's fusion proteins F1 and F2 in these six isolates showed the presence of point mutations in form of nucleic acid substitutions at positions 82((C→T)), 83((T→C)), 736((A→G)), and 1,633((G→A)). However, the nucleic acid residues at positions 330-347 of the precursor F0 gene, corresponding to the cleavage site of the F0 protein, were found to have remained conserved among the six NDV isolates. A phylogenetic comparison between the six Iranian isolates and the NDVs whose F0 gene sequences were previously deposited in GenBank Database showed that all of the newly characterized Iranian NDV isolates belonged to genotype VII.

Abstract
Newcastle disease (ND) is one of the most lethal diseases of poultry worldwide. It is caused by an avian paramyxovirus 1 that has high genomic diversity. In the framework of an international surveillance program launched in 2007, several thousand samples from domestic and wild birds in Africa were collected and analyzed. ND viruses (NDV) were detected and isolated in apparently healthy fowls and wild birds. However, two thirds of the isolates collected in this study were classified as virulent strains of NDV based on the molecular analysis of the fusion protein and experimental in vivo challenges with two representative isolates. Phylogenetic analysis based on the F and HN genes showed that isolates recovered from poultry in Mali and Ethiopia form new groups, herein proposed as genotypes XIV and sub-genotype VIf with reference to the new nomenclature described by Diel's group. In Madagascar, the circulation of NDV strains of genotype XI, originally reported elsewhere, is also confirmed. Full genome sequencing of five African isolates was generated and an extensive phylogeny reconstruction was carried out based on the nucleotide sequences. The evolutionary distances between groups and the specific amino acid signatures of each cluster allowed us to refine the genotype nomenclature.

Abstract
Wild birds are considered as a natural reservoir of Newcastle disease virus (NDV). However, there is no information about genotype IX NDV from wild birds, especially from Columbiformes. In this study, two genotype IX NDV viruses were isolated from wild birds. One was from Eurasian Blackbird, while the other was from Spotted-necked dove. After purification by plaque technique, complete genomes of both viruses were sequenced. Phylogenetic analysis of partial fusion (F) gene and complete genome indicated both strains belonged to genotype IX. Based on intracerebral pathogenicity index (ICPI), the virus from Eurasian Blackbird was velogenic virus, while the strain from Spotted-necked dove was lentogenic virus. However, both strains showed one of velogenic cleavage sites. In addition, the strain from Eurasian Blackbird showed greater replication ability and generated larger fusion foci in vitro than that of strain from Spotted-necked dove. Comparing all the corresponding protein sequences of both strains, there were only 9 different amino acid residues between them. Furthermore, after analysis of these differences, the information about lentogenic NDV with multi-basic cleavage site was presented.

Abstract
Eight strains of pigeon paramyxovirus type 1 (PPMV-1) were isolated and identified in this study, from diseased pigeon flocks suspected to be infected with PPMV-1 in China between 2010 and 2012. These PPMV-1 isolates were purified using specific-pathogen-free (SPF) chicken embryo cells before full-length genomic sequencing. The complete genome of these isolates contained 15,192 nucleotides, similar to those of Newcastle disease virus (NDV) strains in genotypes V-XI, with the gene order 3'-NP-P-M-F-HN-L-5'. A six-nucleotide insertion was found to be located in the 5' non-coding region of the nucleoprotein gene in our eight PPMV-1 strains when compared with those of genotypes I, II, III, IV and V. The cleavage site of the fusion protein was (112)RRQKRF(117), a feature generally associated with virulent NDV strains. The structural proteins were in accordance with those of other PPMV-1 strains, with the exception of the W protein of pigeon/CHINA/LJL/100605. The length of the W protein was 227 amino acids, in common with PPMV-1 strains, whereas that of pigeon/CHINA/LJL/100605 was only 181 amino acids. Phylogenetic analysis, based on the genomic sequences and sequences of the fusion gene, revealed that our eight isolates should be classified as class II genotype VIb NDVs. To our knowledge, this is the first report to show that the strain pigeon/CHINA/LLN/110713 is similar to strains isolated abroad, but it was isolated in China, which implies that it may have been introduced to China from overseas. Differences between the Chinese and foreign strains were identified in three regions (nucleotide positions 1632-2229, 3023-3310 and 6103-6439). In addition, the values of ICPI and MDT demonstrated that PPMV-1 isolates were mesogenic or lentogenic, and virulence studies showed that these PPMV-1 strains were non-pathogenic in chickens, but they induced the generation of antibodies in vivo.

Abstract
Since 2006, the members of the molecular epidemiological working group of the European "EPIZONE" network of excellence have been generating sequence data on avian influenza and avian paramyxoviruses from both European and African sources in an attempt to more fully understand the circulation and impact of these viruses. This review presents a timely update on the epidemiological situation of these viruses based on sequence data generated during the lifetime of this project in addition to data produced by other groups during the same period. Based on this information and putting it all into a European context, recommendations for continued surveillance of these important viruses within Europe are presented.

Abstract
Some pigeon paramyxovirus type 1 (PPMV-1) strains exhibit low virulence in chickens, despite their fusion (F) protein's multi-basic cleavage site. To elucidate the molecular basis of the low pathogenicity of these strains, we constructed an infectious full-length cDNA clone of PPMV-1 strain AV324. This strain is non-virulent for chickens, although its F protein contains the typical virulence motif (112)RRKKRF(117). By using reverse genetics, we exchanged the F genes of AV324 and a virulent Newcastle disease virus (NDV) strain (Herts) and evaluated the recovered chimeric viruses for their pathogenicity in 1-day-old chickens and in embryonated eggs. Our results show that the F protein of AV324, and probably those of similar PPMV-1 strains, are functionally not different from those of virulent NDV strains and that the difference in pathogenicity must be determined by other factors.

Abstract
Forty-four Newcastle disease virus (NDV) strains, obtained between 2002 and 2007 from different poultry species in Nigeria, Niger, Burkina Faso and Cameroon, were phylogenetically analysed based on partial F sequences. Lineage 2 viruses were genetically identical or similar to the locally used LaSota vaccine strain and were mostly detected in commercial farms. Lineage 1, 3 and 4 strains were only sporadically found, and their origin was less clear. Twenty-one strains from backyard farms and live bird markets formed three new clusters within lineage 5, tentatively named 5f, 5g and 5h. All of these strains were predicted to be virulent based on their F protein cleavage site sequence. Minimal genetic distances between new and previously established sublineages ranged from 9.4 to 15.9%, and minimal distances between the new sublineages were 11.5 to 17.3%. Their high genetic diversity and their presence in three different Sub-Saharan countries suggest that these new sublineages represent the NDV variants indigenous to West Africa.
