“…There are 13 described AAvV serotypes (AAvV‐1 to ‐13) based on neuraminidase inhibition tests and hemagglutination inhibition (HI), and eight another putative serotypes have been recently isolated (AAvV‐14 to ‐21) (Jeong et al., ; Lee et al., ; Neira et al., ; Thampaisarn et al., ; Thomazelli et al., ; Yamamoto, Ito, & Ito, ). While very limited information is known about the biological and molecular characteristics of AAvV‐2 to ‐21, extensive study has been mainly conducted on AAvV‐1 (Newcastle disease virus, NDV) (Cardenas‐Garcia et al., ; Umali, Ito, Katoh, & Ito, ).…”

Up to now only nine whole genome sequences of avian avulavirus 6 (AAvV-6) had been documented in the world since the first discovery of AAvV-6 (AAvV-6/duck/HongKong/18/199/77) at a domestic duck in 1977 from Hong Kong of China. Very limited information is known about the regularities of transmission, genetic and biological characteristics of AAvV-6 because of the lower isolation rate and mild losses for poultry industry. To better further explore the relationships among above factors, an AAvV-6 epidemiological surveillance of domestic poultry and wild birds in six provinces of China suspected of sites of inter-species transmission and being intercontinental flyways during the year 2013-2017 was conducted. Therefore, 9,872 faecal samples from wild birds and 1,642 cloacal and tracheal swab samples from clinically healthy poultry of live bird market (LBM) were collected respectively. However, only one novel hemagglutination-negative AAvV-6 isolate (AAvV-6/mallard/Hubei/2015) was isolated from a fresh faecal sample obtained from mallard at a wetland of Hubei province. Sequencing and phylogenetic analyses of this AAvV-6 isolate (AAvV-6/mallard/Hubei/2015) indicated that this isolate grouping to genotype I were epidemiological intercontinentally linked with viruses from the wild birds in Europe and America. Meanwhile, at least two genotypes (I and II) are existed within serotype AAvV-6. In additional, this novel hemagglutination-negative AAvV-6 isolate in chicken embryos restored its hemagglutination when pre-treated with trypsin. These findings, together with data from other AAvV-6, suggest potential epidemiological intercontinental spreads among AAvV-6 transmission by wild migratory birds, and reveal potential threats to wild birds and domestic poultry worldwide.

“…In 2008, a study showed APMV‐8 seroprevalence of 48% in commercial chicken in the United States (Warke et al., ). Recently, APMV‐8 was isolated form tundra swan from Shimane, Japan (Umali et al., ). Complete genome sequence of APMV‐8 strain Delaware and pintail/Wakuya/20/78 was found 15 342 nts long (Paldurai et al., ).…”

“…Interestingly, it has been shown that double‐crested cormorant is an important reservoir of APMVs in the wild bird population (Cross et al., ). Recently, prevalence of APMVs in migratory water fowl has been reported from Japan suggesting the species’ specific pattern of APMVs (Umali et al., ). Similarly, pigeons and mallards have been suggested to be the reservoir of APMVs (Tian et al., ; Teske et al., ; Tolf et al., ).…”

Avian paramyxoviruses (APMVs) have been reported from a wide variety of avian species around the world. Avian paramyxoviruses are economically significant because of the huge mortality and morbidity associated with it. Twelve different serotypes of APMV have been reported till date. Avian paramyxoviruses belong to the family Paramyxoviridae under genus Avulavirus. Newcastle disease virus (APMV-1) is the most characterized members among the APMV serotypes. Complete genome sequence of all twelve APMV serotypes has been published recently. In recent years, APMV-1 has attracted the virologists for its oncolytic activity and its use as a vaccine vector for both animals and humans. The recombinant APMV-based vaccine offers a pertinent choice for the construction of live attenuated vaccine due to its minimum recombination frequency, modular nature of transcription and lack of DNA phase during its replication. Although insufficient data are available regarding other APMV serotypes, our understanding about the APMV biology is expanding rapidly because of the availability of modern molecular biology tools and high-throughput complete genome sequencing.

“…To avoid interference by maternal NDV antibodies with vaccine vector performance, we created a chimeric virus ( ch NDV FHN PMV8 H5 ) by substituting the envelope glycoproteins hemagglutinin-neuraminidase (HN) and fusion protein (F) of NDV by those of APMV-8 and expressing H5 of HPAIV [ 13 ]. APMV-8 was chosen as donor of HN and F because of its apathogenicity for poultry [ 14 ], description of only weak cross-reactivity between APMV-1 and APMV-8 [ 15 , 16 ] and low prevalence [ 17 – 19 ]. Vaccination with this chimeric vector HPAIV-H5-vaccine resulted in efficient protection against HPAIV H5N1 infection in chickens with NDV specific maternal antibodies (MDA) [ 1 ].…”

BackgroundProtection against infection by Newcastle disease virus (NDV), also designated as avian paramyxovirus subtype-1 (APMV-1), is mediated by immune responses to the two surface glycoproteins, hemagglutinin-neuraminidase (HN) and fusion (F) protein. Thus, a chimeric APMV-1 based vaccine that encodes APMV-8 HN- and F-proteins and expresses the hemagglutinin of avian influenza virus (AIV) H5N1, is able to protect against HPAIV H5N1 but fails to protect against NDV [PLoS One8:e72530, 2013]. However, it is unclear whether avirulent APMV-subtypes, like APMV-8 can induce subtype-specific immunity and protect from a homologous challenge.FindingsAPMV-8 infections of 3- and 6-weeks-old specific pathogen free (SPF)-chickens did not induce any clinical signs but was associated with virus shedding for up to 6 days. Viral replication was only detected in oropharyngeal- and never in cloacal swabs. Upon reinfection with homologous APMV-8, viral shedding was restricted to day 2 and in contrast to naive SPF-chickens, only RNA but no infectious virus was recovered. No protection was induced against virulent NDV challenge, although morbidity and mortality was delayed in APMV-8 primed chickens. This lack of protection is in line with a lack of reactivity of APMV-8 specific sera to APMV-1 HN-protein: Neither by hemagglutin-inhibition (HI) test nor immunoblot analyses, cross-reactivity was detected, despite reactivity to internal proteins.ConclusionsImmune responses mounted during asymptomatic APMV-8 infection limit secondary infection against homologues reinfection and facilitates a delay in the onset of disease in a subtype independent manner but is unable to protect against Newcastle disease, a heterologous APMV-subtype.Electronic supplementary materialThe online version of this article (doi:10.1186/1743-422X-11-179) contains supplementary material, which is available to authorized users.
