“…Moreover, Anseriformes and Charadriiformes were assumed to be the most likely to introduce the virus, and therefore should be the focus of active surveillance, to indentify virus before it spills over to other species. (Dundon et al, 2012) summarized genetic data generated in Europe between 2006 and 2011 giving some recommendations for surveillance improvement and harmonization. The project results provided important information about the genetic make-up of HPAI H5N1 virus and other viruses isolated in Europe, and underlined the key role of movements of infected wild birds along multiple migratory routes in generating new chimeric viruses.…”

An extensive literature review was performed to provide insights on the effect of biosecurity and control measures on the risk of introduction and spread of avian influenza in the domestic poultry sector, whether there are gaps in surveillance on wild birds, and to investigate the trigger thresholds for early detection activities through passive surveillance. A total of 1390 articles were retrieved from on-line databases, including Thomson-Reuters Web of Knowledge, PubMed, Ovid and Medline. After removing duplicates 788 studies were screened, and 194 papers were fully read to evaluate whether they could provide reliable information. Twenty-seven papers were considered relevant for assessing the effect of biosecurity and control measures, 7 were included in the assessment of early detection thresholds, and 66 provided information on surveillance gaps in wild birds. Due to the different types of studies included in the review, it resulted impossible to make direct comparison between the results obtained in the articles, as many of them did not report quantitative assessments of the effects of interest. Instead of a formal comparison between studies, the results were reported to provide recommendations on the research questions, also supplying evidences obtained through quantitative analysis and mathematical modeling. Nevertheless it was possible to assess the likely effects of control measures such as pre-emptive culling of farms nearby infected premises, ring vaccination and compartmentalization. Insights on early detection measures provided useful information to reconsider the passive surveillance thresholds to be accounted for to avoid the undetected circulation of avian influenza. The reporting of surveillance on wild birds allowed to identify species to be integrated within the commonly considered target species, and procedures to optimize activities by focusing on defined areas and temporal periods, in the context of a fine tuned Risk Based Surveillance plan. © IZSVe, 2016Key words: avian influenza, biosecurity, surveillance, early detection, introduction, spread Disclaimer: The present document has been produced and adopted by the bodies identified above as authors.

“…Poultry, especially chicken, is a major source of protein, and there is a large demand for enhanced production of poultry products due to the growth of the global human population ( 1 , 2 ). However, infectious diseases caused by viruses such as avian influenza virus (AIV) and Newcastle disease virus (NDV) threaten the poultry industry and food safety by infecting and spreading diseases in a huge number of poultry flocks, resulting in enormous economic losses ( 3 ). AIV frequently changes its antigenic properties via genetic mutations and reassortment, which makes it more difficult to develop effective preventative methods including vaccines ( 4 ).…”

Modification of surface glycan by expression of beta-1,4-N-acetyl-galactosaminyltransferase (B4GALNT2) confers resistance to multiple viruses infection in chicken fibroblast cell

IntroductionInfectious viruses in poultry, such as avian influenza virus (AIV) and Newcastle disease virus (NDV), are one of the most major threats to the poultry industry, resulting in enormous economic losses. AIVs and NDVs preferentially recognize α-2,3-linked sialic acid to bind to target cells. The human beta-1,4-N-acetyl-galactosaminyltransferase 2 (B4GALNT2) modifies α-2,3-linked sialic acid-containing glycan by transferring N-acetylgalactosamine to the sub-terminal galactose of the glycan, thus playing a pivotal role in preventing viruses from binding to cell surfaces. However, chickens lack a homolog of the B4GALNT2 gene.MethodsHere, we precisely tagged the human B4GALNT2 gene downstream of the chicken GAPDH so that the engineered cells constitutively express the human B4GALNT2. We performed a lectin binding assay to analyze the modification of α-2,3-linked sialic acid-containing glycan by human B4GALNT2. Additionally, we infected the cells with AIV and NDV and compared cell survivability, viral gene transcription, and viral titer using the WST-1 assay, RT-qPCR and TCID50 assay, respectively.ResultsWe validated human B4GALNT2 successfully modified α-2,3-linked sialic acid-containing glycan in chicken DF-1 cells. Following viral infection, we showed that human B4GALNT2 reduced infection of two AIV subtypes and NDV at 12-, 24-, and 36-hours post-infection. Moreover, cells expressing human B4GALNT2 showed significantly higher cell survivability compared to wild-type DF-1 cells, and viral gene expression was significantly reduced in the cells expressing human B4GALNT2.DiscussionCollectively, these results suggest that artificially expressing human B4GALNT2 in chicken is a promising strategy to acquire broad resistance against infectious viruses with a preference for α-2,3-linked sialic acids such as AIV and NDV.

“…It is known that birds of the Anseriformes order are the reservoir of lentogenic NDV in nature ( 1 ). Thousands of cases of isolation of lentogenic strains from wild birds during monitoring for influenza virus have been described, but the origin and reservoir of velogenic NDV in nature are still unknown ( 2 ). From 1975 to 2010 there were several outbreaks of NDV among the local population of cormorants in North America ( 3 ).…”

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.
