Abstract
A total of 1007 samples (910 fecal droplets and 97 cloacal swabs) were collected from 14 species of migratory wild birds in most wetlands during 3 successive migration seasons from September to March (2015-2018) in Southern Egypt. The samples were propagated in embryonated chicken eggs and positive allantoic fluids by hemagglutination test were tested for Newcastle disease virus (NDV) and avian influenza virus (AIV) prevalence using RT-PCR and specific primers targeting the NDV fusion (F) and AIV matrix genes. Further subtyping of the AIV hemagglutinin (HA) and neuraminidase (NA) was conducted, and representative isolates were selected and sequenced for full F gene of NDVs and HA and NA genes of the AIV. Overall isolation rate of hemagglutinating viruses was 5.56% (56/1007), from them 5.36% (3/56) AIV, 85.71% (48/56) NDV and 8.93% (5/56) co-infection of NDV and AIV was detected. The sequences analysis of full F genes of 10 NDV isolates revealed that they have multi-basic amino acid motifs 111E/GRRQKR/F117 as velogenic strains with nucleotides and amino acids similarities of 96-100%. In addition, they phylogenetically clustered into groups and subgroups within genotype VII.1.1 and sub-genotype VIIj with a close relation to NDVs isolated from chickens in Egypt. The AIV H5N8 subtype was in clade 2.3.4.4b with a highly pathogenic nature and close relation to Egyptian domesticated H5N8 viruses rather than those from wild birds. The current data showed the contribution of migratory birds to the continuous circulation of virulent NDV and AIV H5N8 among domesticated chickens in Southern Egypt.

Abstract
Pigeon paramyxovirus type 1 (PPMV-1), a variant of Newcastle disease virus (NDV), causes severe Newcastle disease (ND) in pigeons. However, there is no PPMV-1 vaccine available worldwide. In this study, a strain of PPMV-1 was isolated from outbreaks in a vaccinated racing pigeon (Columbia livia) loft in China, namely, PPMV-1/pigeon/Gansu/China/02/2020 (GS02). Experimental infection with GS02 showed mortality rates of 100% and 87.50% in 4- and 12-week-old pigeons, respectively, suggesting that GS02 is virulent and more sensitive to young pigeons. The whole genome of GS02 determined the fusion (F) protein possessing virulence cleavage site 112RRQKRF117. Phylogenetic analysis indicated that GS02 was a subgenotype VI.2.1.1.2.2 (VIk) of Class II NDV and more closely related to the JS/06/20/Pi (MW271791) strain, but it was far from the genetic distance from the commercial vaccine chicken-origin La Sota strain. Using inactivated GS02 as a vaccine candidate and inactivated vaccine La Sota to immunize the pigeons, both of them provided complete protection against GS02 challenge. The GS02 vaccine candidate induced higher antibody titers than the La Sota vaccine, and cross-reactivity testing showed antigenically slight differences between GS02 and La Sota. These results indicated that the GS02 candidate could be a potential pigeon-derived vaccine for the prevention and control of PPMV-1 in pigeons.

Abstract
Pigeon paramyxovirus type 1 (PPMV-1) infection causes high morbidity in pigeons, resulting in a significant burden to the poultry industry. In this study, we isolated three PPMV-1 strains from diseased pigeons collected in Guangdong Province, South China, from June 2017 to April 2019. Genetic analysis revealed that these three PPMV-1 strains and most of the PPMV-1 strains isolated from China after 2011 were clustered into sub-genotype VI.2.1.1.2.2. Our Bayesian analysis revealed that the VI.2.1.1.2.2 viruses might have originated in Europe. Phylogeographic analyses revealed that East and South China might have played a key role in seeding the VI.2.1.1.2.2 PPMV-1 epidemic in China. To characterize the effect of age at infection on the outcome of PPMV-1 infection in pigeons, we investigated the pathogenesis and transmission of the pigeon/Guangdong/GZ08/2017 (GZ08) virus in 3-, 6-, and 12-week-old pigeons. Two of six 12-week-old pigeons inoculated with GZ08 survived, and all of the 3- and 6-week-pigeons inoculated with GZ08 died. Moreover, the GZ08 virus could be transmitted to 3-, 6-, and 12-week-old naïve contact pigeons. The lethality of the GZ08 virus through contact with 3-, 6-, and 12-week-old pigeons was 100%, 66.7%, and 0%, respectively, suggesting that the transmissibility of the GZ08 virus was stronger in young pigeons. These findings demonstrated that East and South China was the epicenter for dissemination of VI.2.1.1.2.2 PPMV-1, and age at infection has an impact on the outcome of PPMV-1 infection in pigeons.

Abstract
Newcastle disease is an important poultry disease that also affects Columbiform birds. The viruses adapted to pigeons and doves are referred to as pigeon paramyxoviruses 1 (PPMV-1). PPMV-1 are frequently isolated from pigeons worldwide and have the potential to cause disease in chickens. The complete genomes of 18 PPMV-1 isolated in China during 2012–2018 were sequenced by next-generation sequencing (NGS). Comprehensive phylogenetic analyses showed that five of the viruses belong to sub-genotype VI1.2.1.1.2.1 and 13 isolates belong to sub-genotype VI.2.1.1.2.2. The results demonstrate that these sub-genotypes have been predominant in China during the last decade. The viruses of these sub-genotypes have been independently maintained and continuously evolved for over 20 years, and differ significantly from those causing outbreaks worldwide during the 1980s to 2010s. The viral reservoir remains unknown and possibilities of the viruses being maintained in both pigeon farms and wild bird populations are viable. In vivo characterization of the isolates’ pathogenicity estimated mean death times between 62 and 114 h and intracerebral pathogenicity indices between 0.00 and 0.63. Cross-reactivity testing showed minor antigenic differences between the studied viruses and the genotype II LaSota vaccine. These data will facilitate PPMV-1 epidemiology studies, vaccine development, and control of Newcastle disease in pigeons and poultry.

Abstract
Newcastle disease virus (NDV) is a major threat to the poultry industry worldwide, with a diversity of genotypes associated with severe economic losses in all poultry sectors. Class II genotype VII NDV are predominant in the Middle East and Asia, despite intensive vaccination programs using conventional live and inactivated NDV vaccines. In Egypt, the disease is continuously spreading, causing severe economical losses in the poultry industry. In this study; the protective efficacy of a commercial, inactivated recombinant genotype VII NDV–matched vaccine (KBNP-C4152R2L strain) against challenge with the velogenic NDV strain (Chicken/USC/Egypt/2015) was evaluated in commercial layers. Two vaccination regimes were used; live NDV genotype II (LaSota) vaccine on days 10, 18, and 120, with either the inactivated NDV genotype II regime or inactivated NDV genotype VII–matched vaccine regime on days 14, 42, and 120. The 2 regimes were challenged at the peak of egg production on week 26. Protection by the 2 regimes was evaluated after experimental infection, based on mortality rate, clinical signs, gross lesions, virus shedding, seroconversion, and egg production schedule. The results show that these 2 vaccination regimes protected commercial layer chickens against mortality, but some birds showed mild clinical signs and reduced egg production temporarily. However, the combination of live NDV genotype II and recombinant inactivated genotype VII vaccines provided better protection against virus shedding (20% and 0% vs. 60% and 40%) as assessed in tracheal swabs and (20% and 0% vs. 20% and 20%) in cloacal swabs collected at 3 and 5 D post challenge (dpc), respectively. In addition, egg production levels in birds receiving the inactivated NDV genotype VII–matched vaccine regime and in those given inactivated genotype II vaccines were 76.6, 79, 82, and 87.4% and 77.7, 72.5, 69, and 82.5% at 7, 14, 21, and 28 dpc, respectively. The results of this study indicate that recombinant genotype-matched inactivated vaccine along with a live attenuated vaccine can reduce virus shedding and improve egg production in commercial layers challenged with a velogenic genotype VII virus under field conditions. This regime may ensure a proper control strategy in layers.

Abstract
This study was conducted to characterize the immunological parameters of chickens vaccinated with two formulated inactivated vaccines, water in oil (WO) and water in oil in water (WOW), prepared from velogenic Newcastle disease virus (vNDV) genotype VIIj isolated from outbreak among vaccinated chickens. Six groups (G1-G6) of commercial broiler chickens were established (n = 20). The G1-G3 were received homologous (WO and WOW) and heterologous (LaSota) inactivated vaccines, respectively. The G4 was vaccinated with live heterologous (LaSota) vaccine, while G5 and G6 were kept as control positive and control negative non-vaccinated groups. The antibody titers were measured against vNDV and LaSota antigens using hemagglutination inhibition (HI) test, the cytokine gene expressions of IFNγ, IL1β, IL4, IL6, IL8, and IL18 were quantified using real-time RT-PCR, and the virus shedding was titrated on chicken embryo fibroblast cells after challenging by vNDV. The classical clinical signs and 100% mortality were observed only in G5 after vNDV challenging. The highest HI titers were detected in G1, G2, and G3 using NDV/168 antigen with no significant differences among them. These groups showed higher HI titer than G4 (2-4log2). Cytokine gene expression of IFNγ, IL1, IL6, IL8, and IL18 were significantly downregulated in vaccinated chickens with upregulation of IL4 than non-vaccinated challenge group. Viral shedding titers were significantly (0.0001, p ≤ 0.001) reduced in all samples form vaccinated chickens. In conclusion, the prepared vaccines produced highly efficient immunological responses and could be used for controlling the NDV infection.

Abstract
The avian infectious disease, Newcastle disease (ND), caused by Newcastle disease virus (NDV) can cause severe economic losses to poultry whether vaccinated or not in many countries. In this study, a strain of NDV isolated from an outbreak in China was subjected to biological, phylogenetic and genetic characterization. The results showed that the mean death time (MDT) was 52.4 h and the intracerebral pathogenicity indices (ICPI) value was 1.95. In addition, amino acid sequencing result showed that it had a sequence 112R-R-Q-R-R↓F117 at fusion protein cleaving site (FPCS) indicating a velogenic strain. And its genome length is 15,192 nucleotide (nt) with the conserved complementary 3' leader and 5' trailer regions encoding six genes, 3'-NP-P-M-F-HN-L-5'. Based on phylogenetic analyses for hyper-variable region and complete genome of F gene, the strain studied here can be clustered into genotype IX, Class II, which has little evolution distance with strains of genotype III, being considered as a transitional strain in the evolution history of NDV. The rescue of infectious cDNA is proceeded in 9-day-old embryonated SPF chicken eggs. Despite the death of the first generation, the allantoic fluid harvested from the first generation lost its pathogenicity after passage. And we found the phenomenon happened due to the antibody appearing in the allantoic fluid. These findings offer our understanding of circulating strains of NDV in China and lay scientific foundations for making more efficient vaccines for Newcastle disease.

Abstract
Simple Summary Newcastle disease is an acute fatal disease of poultry. All broiler chickens and 8/15 pigeons were killed when infected intramuscularly (IM), while 7/10 chickens and only 1/15 pigeons were killed when infected intranasally (IN) with the virus in an experimental setting. Chickens in contact with infected pigeons developed severe respiratory, digestive and nervous signs. The mortality rates in chickens in contact with IM and IN infected pigeons were 2/5 and 3/5, respectively. Chickens in contact with IM infected pigeons had higher viral shedding titres than those in contact with IN infected pigeons. Free-range pigeons are considered an efficient carrier and transmitter of NDV-VIId to commercial broiler chickens raised in open houses. Abstract Newcastle disease is an acute fatal disease of poultry. The aim of this study was to determine the dynamics of the transmission of avian avulavirus (velogenic viscerotropic Newcastle disease-genotype VIId) from either intramuscularly (IM)- or intranasally (IN) infected 8-week-old Egyptian Baladi pigeons in contact with commercial Arbor Acres broiler chickens (4 weeks of age). The mortality of IM infected chickens and pigeons was 10/10 for chickens and 8/15 for pigeons, while the mortality of IN infected chickens and pigeons was 7/10 for chickens and only 1/15 for pigeons. The concentration of viral shedding in the oropharynx was higher than that in the cloaca for both IN and IM infected pigeons. Pigeons infected IN continued shedding the virus from the oropharynx from the 4th day post-infection (dpi) up to the 16th dpi, while IM infected pigeons stopped oropharyngeal shedding at the 11th dpi. Chickens in contact with infected pigeons developed severe respiratory, digestive and nervous signs. The mortality rates in chickens in contact with IM and IN infected pigeons were 2/5 and 3/5, respectively. Chickens in contact with IM infected pigeons showed higher viral shedding titres in both the oropharynx and cloaca than chickens in contact with pigeons infected IN. In conclusion, free-range pigeons are considered an efficient carrier and transmitter of NDV-VIId compared to commercial broiler chickens raised in open houses.

Arch Virol 2018; 163:2971-2984.

Abstract
Pigeon paramyxovirus type 1 (PPMV-1) infection is enzootic in pigeon flocks and poses a potential risk to the poultry industry in China. To gain insight into the biological characteristics and transmission routes of circulating PPMV-1 in pigeons, 13 PPMV-1 isolates from domestic pigeons isolated during 2011-2015 in Guangxi province, China, were characterized using a pathogenicity assessment and phylogenetic analysis. All PPMV-1 isolates were mesogenic or lentogenic strains and had a mean death time (MDT) in 9-day-old SPF chicken embryos and a intracerebral pathogenicity index (ICPI) values of 54-154 h and 0.00-0.90, respectively. Analysis of the F and HN gene sequences of the PPMV-1 isolates and the Newcastle Disease (ND) vaccine strain La Sota, revealed that the nucleotide sequence similarity of the F and HN genes were all < 85% between the PPMV-1 isolates and La Sota, significantly lower than those > 98% among the PPMV-1 isolates. The amino acids sequence of the F protein at the cleavage site of the 13 PPMV-1 isolates was 112RRQKR↓F117, characteristic of virulent Newcastle disease virus (NDV). All 13 isolates were classified as sublineage 4b by phylogenetic analysis and evolutionary distances, based on the F gene sequences. It was also found that the 13 isolates were divided into two novel sub-groups of sublineage 4b, sub-sublineages 4biig and 4biih. Since these two novel sub-sublineages had two different geographic sources, we speculated that they represent two different transmission routes of PPMV-1 in China. Phylogenetic analysis of these isolates will help to elucidate the sources of the transmission and evolution of PPMV-1 and may help to control PPMV-1 infection in the pigeon industry in China.

Abstract
A rock pigeon (Columba livia) caught in Akihabara, Tokyo, showed
neurological symptoms, such as head tilt and circling. Pathological examinations revealed
abundant Sarcocystic cysts in the skeletal muscle and myocardium with mild myositis, and
numerous schizonts and sarcocysts with severe multifocal granulomatous T-lymphocytic
infiltration in the central nervous system. A Sarcocystis
calchasi-specific gene was detected in the muscle and brain. This case indicates
S. calchasi was distributed in Japan and caused severe encephalitis to
rock pigeons.
