[PMID: 37764199 PMCID: PMC10536639 DOI: 10.3390/microorganisms11092355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 09/13/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
There is growing interest in emerging viruses that can cause serious or lethal disease in humans and animals. The proliferation of cloacal virome studies, mainly focused on poultry and other domestic birds, reveals a wide variety of viruses, although their pathogenic significance is currently uncertain. Analysis of viruses detected in wild birds is complex and often biased towards waterfowl because of the obvious interest in avian influenza or other zoonotic viruses. Less is known about the viruses present in the order Passeriformes, which comprises approximately 60% of extant bird species. This review aims to compile the most significant contributions on the DNA/RNA viruses affecting passerines, from traditional and metagenomic studies. It highlights that most passerine species have never been sampled. Especially the RNA viruses from Flaviviridae, Orthomyxoviridae and Togaviridae are considered emerging because of increased incidence or avian mortality/morbidity, spread to new geographical areas or hosts and their zoonotic risk. Arguably poxvirus, and perhaps other virus groups, could also be considered "emerging viruses". However, many of these viruses have only recently been described in passerines using metagenomics and their role in the ecosystem is unknown. Finally, it is noteworthy that only one third of the viruses affecting passerines have been officially recognized.

Abstract
In August 2022 on a backyard farm in the Moscow region of Russia, mortality was observed among chickens, and all 45 birds of a particular farm died or were slaughtered after the onset of symptoms within a few days. Paramyxovirus was isolated from the diseased birds. Based on the nucleotide sequences of the F and NP gene fragments, it was determined that the virus belonged to subgenotype VII.1 AAvV-1 class II. The cleavage site of the F gene 109SGGRRQKRFIG119 and T in 546 and 555 position of the NP gene were typical for the velogenic type. The genetically closest NDV isolates were found in Iran. The mean time of death of 10-day-old chicken embryos upon infection with the minimal infectious dose was 52 h, which is typical for the velogenic pathotype. The virus caused 100% death of six-week-old chickens during oral infection as well as 100% mortality of all contact chickens, including those located in remote cages, which proves the ability of the virus to spread not only by the fecal-oral route but also by the aerosol route. That demonstrates a high level of pathogenicity and contagiousness of the isolated strain for chicken. However, mice intranasally infected with high doses of the virus did not die.

Abstract
Wild-caught Eurasian tree sparrows (Passer montanus) were experimentally inoculated with genotype VII velogenic Newcastle disease virus (NDV) APMV1/chicken/Japan/Fukuoka-1/2004 to investigate the susceptibility and pathogenesis of infected sparrows. Intranasal inoculation of two groups with high or low doses of the virus resulted in the mortality of some birds in both groups on days 7-15 postinoculation. Neurologic signs, ruffled feathers, labored breathing, emaciation, diarrhea, depression, and ataxia were observed in a few birds that eventually succumbed to death. The inoculation of the higher viral load resulted in higher mortality and hemagglutination inhibition antibody detection rates. Tree sparrows that survived the 18-day observation period after inoculation exhibited no apparent clinical signs. Histologic lesions in dead birds were observed in the nasal mucosa, orbital ganglion, and central nervous system, accompanied by NDV antigens detected by immunohistochemistry. Viral inclusion bodies were rarely observed in the cytoplasm of neurons. NDV was isolated from the oral swab and brain of dead birds but not from other organs, including the lung, heart, muscle, colon, and liver. In another experimental group, tree sparrows were intranasally inoculated with the virus and then examined 1-3 days later to examine the early pathogenesis of the disease. Inoculated birds exhibited inflammation of the nasal mucosa with viral antigens, and virus was isolated from some oral swab samples on days 2 and 3 postinoculation. The results of the present study suggest that tree sparrows are susceptible to velogenic NDV, and the infection could be fatal, although some birds can exhibit asymptomatic or mild infection. The unique pathogenesis regarding the neurologic signs and viral neurotropism of velogenic NDV was characteristic in infected tree sparrows.

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
Background Newcastle disease (ND) virus (NDV) is one of the major pathogens in poultry farms that causes severe economic damages to the poultry industry, especially broiler chicken and turkey farms. Despite the endemicity of ND and its many epidemics in the country, the nature of the Iranian strain of the Newcastle virus is still largely unknown. This study aimed to characterise and evaluate NDV isolates obtained from commercial poultry farms in Iran in 2019 through haemagglutinin‐neuraminidase (HN) gene sequencing. Method HN gene of each NDV isolate was amplified and sequenced using specific primers followed by phylogenetic analysis of full length of HN gene open reading frame and amino acid (aa) sequence of HN. Results Phylogenetic analysis of the HN gene showed that the virus is very closely related to genotypes VII and III. Analysis of HN gene nucleotide sequences showed that all isolates encode proteins with a length of 571 aa. Conclusion Results of the present study are useful for a better understanding of molecular epidemiology of indigenous NDV strains and determining important molecular differences between fields and commonly used vaccine strains related to main immunogenic proteins.

Abstract
Despite numerous disease prevention measures and control programs, Newcastle disease (ND) remains one of the most significant infections in poultry worldwide, especially in developing countries. It is known that wild birds, mainly of the Anseriformes order, are the main carrier of lentogenic (non-pathogenic) variants of Newcastle disease virus (NDV) in nature. But the question of the reservoir of velogenic (highly pathogenic) NDV in nature still remains open. In the 1970s, 1990s, and 2000s in North America during epizootics among cormorants, velogenic NDV strains were isolated. It was later concluded that cormorants play an important role in the maintenance and circulation of NDV in North America. New data have been obtained on the circulation of velogenic NDV strains in wild birds in Central Asia: VIIb and XIII genotype strains were isolated from cormorants for the first time in Kazakhstan. Interestingly, outbreaks of NDV registered in poultry in Central and Southern Asia were phylogenetically close to the viruses from cormorants that support the idea that cormorants can serve as the potential reservoir of velogenic NDV in developing countries of Asia. The seasonal migrations of cormorants may contribute to the distribution of the virus throughout Asia but more evidence must be obtained to confirm this hypothesis. There is increasing evidence of the introduction of NDV into the poultry farms from wild nature worldwide. This article continues the discussion on the likelihood of cormorants to serve as a reservoir and carrier of NDV on the Asian continent.

Abstract
Virulent strains of avian orthoavulavirus 1, historically known as Newcastle disease virus (NDV), are widespread and cause high levels of mortality in poultry worldwide. Wild birds may play an important role in the maintenance of Avian orthoavulavirus 1 in nature. Prior to 2014, most of the lentogenic NDV strains isolated from Central Asia were obtained from the avian order Anseriformes (ducks and geese). Wild birds were monitored from 2014-2016 to detect the circulation of NDV. A total of 1522 samples belonging to 73 avian species were examined, and 26 positive samples were identified. The isolates of Avian orthoavulavirus 1 belonged to three genotypes: viruses from doves (Columbiformes) and cormorants (Suliformes) were attributed to the velogenic genotypes VI and XIII, respectively, while the isolate from poultry belonged to lentogenic genotype I. The isolation of Avian orthoavulavirus 1 from doves may confirm their role as a reservoir of pigeon paramyxoviruses (antigenic variant of the genotype VI NDV) in nature and indicates the potential threat of introduction of velogenic strains into the poultry population. Our study describes an epizootic scenario in Kazakhstan among cormorants with mortality among juveniles of up to 3 wk of age and isolation of the NDV from apparently healthy birds. These observations may support the idea that cormorants are one of the potential reservoirs and victims of velogenic Avian orthoavulavirus 1 in Central Asia. The seasonal migrations of cormorants may partially contribute to viral dissemination throughout the continent; however, this hypothesis needs more evidence.
