Technical Summary
There is no single mechanism adopted by viruses to establish a persistent infection, and the propensity for persistence can vary between closely related viral serotypes. Therefore, studying the natural hosts has enormous advantages over model species for dissecting the detailed molecular processes and pathways involved. The suite of biological mechanisms leading to persistence can be complex and the outcome of infection can vary depending on minor variation in the virus, host or indeed other environmental influences. Consequently insights into the entire process of viral pathogenesis leading to persistence is crucial to both identify targets for disease control and in making sure that any interventions are not likely to exacerbate disease. These studies build on the established, integrated and systems approach to animal infection studies that is a unique strength of the work undertaken at Pirbright. The studies in this topic is particularly closely linked to the ‘recognition and control of virus infections’ topic where the host innate and adaptive immune responses have failed to clear an infection.
Marek’s disease virus (MDV) has developed multiple mechanisms for evading clearance by the host for and persisting. Avian hosts have adapted by initiating a balanced immune response that does not cause untoward tissue damage, but restricts virus replication to tolerable levels. Understanding this dynamic equilibrium is challenging, but very important to develop innovative intervention control strategies. African buffalo can become persistently infected with foot and mouth disease virus (FMDV) creating a virus reservoir that influences viral evolution and transmission to cattle. Understanding the process of persistence will be an important component of any future eradication programme in Africa and could identify opportunities to control this disease in cattle. Porcine respiratory and reproductive syndrome virus (PRRSV) strains are poor inducers of type I interferon (IFN) both in vitro and in vivo. PRRSV antagonises the production of type I IFN by infected cells in order to facilitate viral replication and persistence. Indeed, replication of the virus in porcine alveolar macrophages can be controlled by IFN-a treatment.

| Description | The key findings from the studies on persistent infections of three viruses viz. Marek's disease virus (MDV) in poultry, porcine respiratory and reproductive syndrome virus (PRRSV) in pigs, and foot and mouth disease virus (FMDV) in ruminants: 1. MDV latency in tumour cell lines is maintained by epigenetic mechanisms: During latency, MDV expresses a limited set of genes which are kept transcriptionally active with boundaries maintained using specific insulator sequences. We have determined global changes in the methylation of the viral/host promoters by determining the first chicken global DNA methylome of oncogenic virus-transformed cells. 2. CRISPR/Cas9-based in situ gene editing for examining the determinants of MDV persistence: We have developed CRISPR/Cas9-based gene editing tools in MDV-transformed cell lines. We demonstrated that the MDV-encoded oncogene Meq is essential for transformation. Over 300 host dependency factors required for cellular proliferation and the maintenance of the transformed phenotype have been identified using chicken GeCKO library screening of MDV tumour cell line. Gene pathway analysis showed a significant mitochondrial signature. Further analysis using several known mitochondrial inhibitors suggests that mitochondrial function is critical for the continued cellular proliferation. A CRISPR activation system was established to activate latent viral genes in MDV cell lines and demonstrated that activation of pp38/pp24 expression triggers lytic replication. Host factors essential for growth of Avian Leukosis virus subgroup A and J have also been identified using CRISPR library screening and being validated. The identified host genes critical for transformation or viral growth will be useful as targets to interfere with the neoplastic process. 3. COX-2-PGE2 pathway in MDV persistence: Activation of COX-2-PGE2 pathway, essential for MDV replication, can modulate both innate and adaptive immunity against MDV replication, influencing latency. We generated significant new knowledge on the role of metabolism in replication and spread of avian alphaherpesviruses in avian cells. We demonstrated in chickens that inhibition of the COX-2 -PGE2 pathway prevented MDV-induced immunosuppression. 4. Examining the role of T cells in resistance/susceptibility to MDV: We demonstrated that IFN-? producing memory T cells correlate with protection against MD, and vaccination increases both effector and memory T cell IFN-? responses in both genetically resistant and susceptible chicken lines. We identified three immunodominant CD4+ T cell epitopes, which are restricted to MHC B19 (MD-resistant) or B21 (MD-susceptible) haplotypes within PP38 antigen of MDV. Analysis of T cell responses in naïve and vaccinated chickens following infection with a virulent virus provided insight into differential T cell responses in genetically resistant and susceptible chicken lines. Analysis of virus-specific T cell response after infection demonstrated associations between resistance to the disease and (1) magnitude of IFN-gamma producing memory T cell response in naïve birds; (2) greater magnitude of IFN-gamma producing effector T cell responses in vaccinated chickens, (3) a skew of response towards Th2 response and expression of higher lymphocyte-lysis related genes; (4) T cell cytotoxicity impairment in naïve birds regardless of their genetic background. The results provided some information on why vaccinal immunity fails to inhibit persistent infection, while provide protection against the disease. We also analysed the role of gamma-delta T cells and demonstrated that adoptive transfer of these cells reduced viral replication in the lungs and tumour incidence in MDV-challenged chickens. 5. PRRSV non-structural proteins show multiple interactions with host proteins: Using yeast-two-hybrid screens with PRRSV-1 NSP1 and a porcine alveolar macrophage library, we have identified interacting proteins associated with IFN signalling, the NF-?B pathway, ubiquitination, and nuclear transport, suggesting their roles in pathogenesis and persistence of PRRSV. We established a PRRSV reverse genetics system to generate recombinant low and high virulence strains, that will enable functional characterisation of viral proteins in gene-swapping experiments. 6. Follicular dendritic cells in the germinal centre are important in FMDV persistence and immune responses in a mouse model: The importance of FDCs in FMDV persistence was demonstrated as virus decreased significantly when FDC were depleted with recombinant lymphotoxin beta receptor immunoglobulin fusion protein (LTßR-Ig). Moreover, LTß-deficient mice that lacked FDC and normal intact splenic marginal zone, failed to trap and retain FMDV in the germinal centres, failed to generate neutralising antibodies to FMDV and showed impaired FMDV-specific antibody responses. 7. African buffaloes are not a major source of new FMDV variants: We have shown that despite an accumulation of low frequency sequence variants over time, there is no evidence of significant antigenic variation, suggesting that carrier buffalo are unlikely to be a major source of new variants which may infect livestock. We showed that antibody escape does not contribute to persistent infections in buffaloes. Using a combination of transmission experiments, field studies and mathematical modelling, we demonstrated how carrier animals enable FMDV to persist in small buffalo populations. |
| Exploitation Route | 1. MDV immune responses and metabolism: Our studies demonstrating IFN-?-producing T cells as a correlate for protection against MD can be exploited for vaccine development, to assess flock susceptibility and inform interventions for MD control. T cell assays can be used to study responses to other infections and vaccines in chickens. Identification of the COX-2/PGE2 pathway in MD pathogenesis could be explored in developing novel control methods, e.g., COX-2 inhibitor drugs. 2. CRISPR/Cas9-based gene editing for studying MDV biology: Identification of the host factors required for maintaining the transformed phenotype of MDV cell lines gives the opportunity for the study of critical viral and host genes involved in features such as virus-host interactions, neoplastic transformation, and virus latency. The identified genes could also serve as targets for inducing de novo genetic resistance using gene editing approaches. 3. Our PRRSV reverse genetics system was essential in us securing four externally funded projects (three funded by pharmaceutical companies), which aim to produce more effective PRRSV vaccines through genetic modifications. 4. Identification of the role of FDCs in persistence of FMDV in mouse model: These studies will help in the design of vaccines to induce long-term immunity and understand the role of "carrier" animals in the maintenance and spread of infection in wildlife and livestock populations. |

| Title | A ligation and restriction enzyme independent cloning technique: an alternative to conventional methods for cloning hard-to-clone gene segments in the influenza reverse genetics system |
| Description | we developed an easy and efficient ligation and restriction enzyme independent (LREI) cloning method for cloning influenza gene segments into pHW2000 vector. The method involves amplification of megaprimers followed by PCR amplification of megaprimers using a bait plasmid, DpnI digestion and transformation. ligation and restriction enzyme independent (LREI) cloning method represents an alternative strategy for cloning influenza gene segments that have internal restriction sites for the enzymes used in reverse genetics. Further, the problem of genetic instability in bacteria can be alleviated by growing recombinant bacterial cultures at a lower temperature. This technique can be applied to clone any influenza gene segment using universal primers, which would help in the rapid generation of influenza viruses and facilitate influenza research and vaccine development. |

| Title | Establishment of an efficient CRISPR/Cas9 gRNA library screening to identify the host factors required for maintaining the transformed phenotype of MDV tumour cell lines |
| Description | Herpesviruses are large dsDNA viruses that cause widespread, lifelong latent infections in different hosts, through multiple virus-host interactions to create a delicate balance between the virus and the host. CRISPR/Cas9-based gene editing is emerging as a powerful tool to investigate the precise determinants of latency in a number of herpesvirus infections. Marek's disease virus (MDV-1) is a lymphotropic a-herpesvirus associated with latent infections and malignant CD4+ T-cell lymphomas in chicken. MDV-1 has a two-phase life cycle, consisting of a lytic and a latent phase, the latter closely associated with the oncogenesis of the virus, yet the underlying molecular mechanisms of cell transformation remain unclear. Better understanding of the factors that maintain the latency of the virus will provide insights into novel intervention strategies to interfere with the neoplastic process. We have used a high throughput genome-wide CRISPR/Cas9 gene knockout strategy, combined with next generation sequencing to identify the genes critical for maintenance of the transformed phenotype. 339 host genes have been identified being essential for maintaining the transformed phenotype of MDV cell line. |

| Impact | Establishment of the pipeline of CRISPR library screening in chicken cell lines has given the opportunity for the identification factors associated with disease pathogenesis and neoplastic transformation.

| Title | Establishment of an efficient CRISPR/Cas9-based screening pipeline for herpesviruses to study the gene function and streamline the vector platform for recombinant vaccine development |
| Description | The development of both cosmid DNA and Bacterial artificial chromosome (BAC) technologies has greatly facilitated the introduction of mutations into the viral genomes of herpesviruses to study gene functions. However, cloning of viral genomes as BAC plasmid and subsequent mutagenesis is inefficient, time-consuming and may introduce mutations by repeated passages. Following our success in efficient CRISPR/Cas9 editing of the MDV genome in both replicating virus and MDV transformed cell lines and of HVT genome for the recombinant vaccine development, we have developed an efficient CRISPR/Cas9-based screening pipeline for herpesviruses to identify the essential/non-essential genes for study of the gene function and streamline the vector platform for recombinant vaccine development. |

| Impact | Identification of essential and non-essential genes of herpesviruses provided opportunities to study gene function in vitro and in vivo. Knocking out the non-essential genes in the HVT vector can enhance HVT replication in vivo enabling recombinant HVT-based vaccines to induce stronger immune responses. |

Immuno-fluorescence microscopy (IFM) was used to investigate internalisation of FMDV and immune complexed (IC) FMDV at 1-6 hours post infection (hpi) and also to investigate the uptake pathways utilised by non-cell culture and cell culture adapted FMDV in the presence of different pharmacological inhibitors. Western blot, IFM and quantitative RT-PCR was used to analyse viral replication at 0-6, 8, 16 and 24 hpi. Plaque assays were used to investigate the yields of live virus produced in moDC at 0, 4, 8 and 24 hpi. Flow cytometry was used to investigate the changes in IL-12 and IL-10 secretion following FMDV infection at 2, 4 and 6 hpi. MxCAT ELISA was used to investigate the secretion of IFN at different times post infection. |

| Title | Lateral flow detection of avian leukosis viruses and Reticuloendotheliosis virus |
| Description | The system for detecting ALV/REV based on CRISPR-Cas13a, a SHERLOCK reaction system consists of specific RPA primers for amplifying target nucleic acid fragments, Cas13a protein, crRNA, and Lateral flow chromatography test strip for visualized display of results. The assay started with pre-amplification of either a DNA or RNA target input. Amplified targets are then converted to RNA via T7 transcription and detected by Cas13-crRNA complexes, which activate and cleave fluorescent RNA reporters based on its collateral cleavage nature. The result can be visualized using colorimetric lateral flow reaction. The test is rapid, sensitive and specific for detection of ALV/REV at 37°C. The product can commercialized with a great clinical application prospects. |

| Title | The establishment of an efficient pipeline for in situ CRISPR editing of the Marek's disease virus (MDV) genome in lymphoma-derived cell lines |
| Description | The lymphoblastoid cell lines (LCLs) derived from MD lymphomas have served as valuable resources to study virus-host molecular interactions in transformed cells. However, detailed investigations into the functional role of different viral and host determinants in these cells have been difficult due to the lack of tools for in situ manipulation of viral/host genomes in MDV-transformed cell lines. Our recent success in efficient CRISPR/Cas9 editing of the MDV genome in LCLs has demonstrated the potential for targeted editing to dissect the regulatory pathways involved in latency, transformation, reactivation and lytic switch. |

| Title | FMDV LIMS and webtools |
| Description | The Integrative Biology and Bioinformatics (IBB) group has been supplying state-of-the-art bioinformatics tools to the World Reference Labs for the Foot-and-Mouth Disease Virus. All tools revolve around a database of genomic sequences and metadata for FMDV samples. Some tools allow members of the lab to enter, process and annotate new data into the database, generating several kinds of reports. Other web-based tools (the "FMDV Toolbox") allow external users to query the database in several ways. Bioinformatics workflows are hosted on the IBB cluster, and have been implemented as REST web services so as to be decoupled from the web interface. The web interface is currently being redeveloped with the help of a specialised company. |

| Title | Method to predict vaccine matching in-silico |
| Description | Every time a novel viral strain emerges, it is essential to know whether existing vaccines are effective against it. Several lab techniques are available in order to do so, the most widespread one arguably being VNT (virus neutralisation test). However VNT is expensive, difficult to implement and not very reproducible due to batch effects. Being able to reliably predict VNT-derived antibody titres with the computer would be a game changer in the field. We have developed an in-silico model based on machine learning that is able to effectively predict VNT outcomes out of sequencing data. We have shown that the method performs well for FMDV and also, apparently, for influenza. |

| Title | South-African buffalo FMDV sequences |
| Description | We have sequenced FMDV buffalo samples originated from a EEID project entitled: Persistence of a Highly Contagious Pathogen: Ecological and Evolutionary Mechanisms in Foot-And-Mouth Disease Virus. This project aims to understand why a highly contagious pathogen such as FMDV, which induces a rapid host immunity and depletes the supply of susceptible host, is able to persist in isolated buffalo populations and thus avoid auto-extinction. The centre piece of the project is a cohort study which involves an established FMDV-positive breeding herd of ca. 70 buffalo in a 900-hectare enclosure surrounded by double game fencing housing buffalo in isolation from other herds in the Kruger National Park (South Africa). The entire herd is being monitored for three years (animals are sampled every 2 months (serum, tonsil swabs, probang) to trace FMDV transmission events, allowing us to define FMD infection dynamics across the susceptible calf cohorts and amongst adults. So far, FMDV genomes from 101 samples have been deep sequenced by illumina. Samples from the last year captures are currently being analysed and virus is currently being isolated. The second experiment is an experimental study, which involves a group of naïve buffalo experimentally infected with either a SAT-1, SAT-2 or SAT-3 virus. The infected buffalo were then allowed to mingle with susceptible animals and transmission of FMDV to naïve animals was monitored during the acute infection but also from persistently infected animals. So far, FMDV genomes from 48 samples obtained at days 2, 30 and 160 of the experiment have been deep sequenced. |

| Impact | The samples sequenced come from South Africa, which is an LMIC, While FMDV infection in cattle is very well studied, the mechanisms of persistence in buffalo, which is thought to be the natural reservoir of the infection, are not well understood. Such understanding would be essential to inform better policies to understand and manage FMDV, which is an economically important scourge of cloven hooved animals in LMICs. All the sequences will be made available on the Transboundary Portal which is being developed at Pirbright. |
| Title | Viral assembly pipeline |
| Description | The Integrative Biology and Bioinformatics group has developed a data analysis pipeline to obtain sensitive and robust viral assemblies out of high-throughput sequencing data. In spite of the relatively short genomic length of most viruses, assembling of viral sequences can be challenging due to several reasons, such as: low amount of material in the sample, which might require amplification, introducing biases, and/or generates low-quality sequences; uneven coverage due to low-quality material or the genomic material of the virus being RNA; the viral nucleic acid being almost lost in the background of nucleic acid of the host. Our pipeline overcomes most of those problems, and is even able to detect different viral strains being present together in the same sample. It can also be used on metagenomic environmental samples. |

| Title | Viral variant calling pipeline |
| Description | The Integrative Biology and Bioinformatics group has developed a data analysis pipeline to obtain sensitive and robust variant calling for viral sequences out of high-throughput sequencing data. In spite of the relatively short genomic length of most viruses, calling variant for viral sequences can be challenging due to several reasons, such as: low amount of material in the sample, which might require amplification, introducing biases, and/or generates low-quality sequences; very high genome coverage, which slows down most existing variant callers; the presence of a potentially very high number of different haplotypes for RNA viruses, which is an unusual scenario in variant calling. Our fast and sensitive Bayesian pipeline overcomes most of those problems. |

| Title | Zimbabwe FMDV sequences |
| Description | Foot-and-mouth disease virus (FMDV) causes an acute vesicular disease in domestic cloven-hooved animals. However, in the African buffalo (Syncerus caffer) clinical disease is rarely observed and following infection virus is persistently carried in the oesophageal-pharyngeal area of the upper respiratory tract. During the 1990s oesophageal-pharyngeal scrapings were collected from free-living African buffalo in multiple herds in six different geographic areas of Zimbabwe. We sequenced over 140 FMD viruses each belonging to one of the Southern African Territories (SAT) serotypes (SAT 1, SAT 2 and SAT 3) from primary bovine thyroid cells. |
| Type Of Material | Database/Collection of data |
| Year Produced | 2018 |
| Provided To Others? | No |
| Impact | This dataset has been generated from samples collected in Zimbabwe, which is a low-income country. Those viral sequences will be essential to help elucidating the nature of persistent FMDV infection in African buffalo, which is supposed to be the main virus reservoir in vivo. As the samples track viral infection and evolution over several years and across a number of different herds in different national parks and conservatories, the dataset will also inform better animal management and conservation. A better understanding of FMDV persistence would also be essential to mitigate the economic burden generated by the disease, which is a scourge of cloven-hoofed animals in LMICs. All the sequences will be made available through the Transboundary Pathogen portal that is being developed at Pirbright. |

| Organisation | Animal and Plant Health Agency |
| Country | United Kingdom |
| Sector | Public |
| PI Contribution | This project brought together eight leading scientific organizations in the UK to develop strategies for mitigating bird flu. Its main objective is to devise tools that bridge significant knowledge gaps concerning the virus's prevalence in wild birds and the factors leading to its emergence in poultry. We are exploring molecular determinants potentially related to changes in virus virulence, antigenicity, cross-species transmission, and the capacity to infect humans. |
| Collaborator Contribution | The partners provided field samples and sequence data of viruses isolated from disease outbreaks. This data was used to identify molecular determinants linked to virus phenotype changes. |
| Impact | At the frontline, ethnographic surveys were designed and implemented to understand farmers perceptions of farm biosecurity. Studies highlighted the need for an improved understanding of key biosecurity risk points and the implementation of effective biosecurity practices. Outputs showed that high quality facilities and management systems can be undermined by weaknesses in procedural compliance. As such, targeted farm worker education could help mitigate against future incursions which will be addressed in the follow-on research programme, FLUTRAILMAP. Recent work indicates that farm-to-farm spread is rare and that the virus is not spread long distances as an aerosol. Linked to biosecurity, virulence for poultry and the potential role of airborne spread of the virus was evaluated. Active sampling on infected premises across different hosts supported the experimental evaluation of pathogenesis and transmission (FLUMAP: Pathogenesis) by demonstrating that this virus is not spread long distances by the aerosol route (FLUMAP: Aerosol). Further, studies demonstrated that different bird species represent different risk levels for excretion of infectious material and potential transmission routes (FLUMAP: Gannets; FLUMAP: Environment; Pheasants). Ultimately, experimental, field and genetic data supported a lack of aerosol spread between premises. In support of this, genetic analysis of over 800 full bird flu virus genomes demonstrated that farm-to-farm spread was very rare with independent incursions from wild birds driving infection in poultry (FLUMAP: Genetics; Phylodynamics). Several genetic characteristics were identified that expanded our knowledge, explaining the explosive success of the current H5N1 bird flu viruses to spread fast and infect a greater range of bird species including a shift of infection dynamics to affect seabirds (FLUMAP: Infection dynamics) and via long distance and transatlantic spread (Transatlantic). These traits have contributed to the current H5N1 viruses having increased fitness across multiple species. Contemporary H5N1 viruses have enhanced fitness to infect, transmit and persist in birds, but remain of low risk to humans (FLUMAP: Characterization; Human Case). This project has defined a role for multiple virus genes which have switched and evolved over time to act together in a highly efficient manner. To better understand key species that may tolerate infection with this virus in the absence of clinical disease, sampling of hunter harvested wild birds was undertaken. Virus positive birds were detected in a small subset of Teal, Wigeon, and Pink-Footed Geese although carcasses were not available to evaluate the distribution of virus in these birds (Healthy birds). Further assessment of different avian species using this approach are planned. Gannet populations around the UK have been severely impacted by High Pathogenicity Avian Influenza (HPAI), at Bass Rock the number of occupied nest sites decreased by over 70%. Linked to the detection of the virus in apparently healthy birds, interrogating survival from infection, and in particular the role of antibodies in birds that may have been infected, but survived infection was a key interest (FLUMAP: Gannets). FLUMAP has enabled the development of a suite of laboratory tools that will enable us to dissect the immune response in birds that may have been exposed to multiple and different influenza viruses in their lifetime. Tools are now available to dissect antibody responses to each of the two different viral surface proteins (both individually and in tandem). How these two different viral coat proteins interact with each other and what optimal protein combinations mean with respect to stability of interaction has also been assessed. These tools will enable a better understanding of how different key surface proteins drive immune responses and what that means where viruses emerge containing different coat proteins. The periodic switching of the neuraminidase (NA) protein (i.e., N8 to N1) is an important factor in influencing the emergence of new strains and the tools developed in FLUMAP will enable the impact of these genetic reassortment events to be assessed. Whilst further outputs are realised from the FLUMAP project, the follow-on project, FLUTRAILMAP, will enable the application of these data to this continually emerging global situation and will enable better prevention and mitigation approaches to be defined. |

| PI Contribution | The highly pathogenic avian influenza virus H5N1 clade 2.3.4.4b is panzootic in birds. Its widespread geographical distribution, sheer numbers of infections and frequent incursions in mammals indicate it to be a virus with pandemic potential. We are working as a consortium to achieve a coordinated in-depth risk assessment of clade 2.3.4.4b viruses particularly zoonotic potential of the current clade 2.3.4.4b H5N1 viruses. |
| Collaborator Contribution | The collaborating partners are jointly providing data and samples necessary for evaluating the threat posed by H5N1 Clade 2.3.4.4b highly pathogenic avian influenza viruses (HPAIV) to human health. This effort aims to understand the risks, potential spillover routes into humans, the virus's capacity to adapt for human transmission, and the probable severity of human infections should they occur. We will meet these objectives through three interconnected work packages: (1) assessing the infection likelihood in non-human mammals that could serve as bridging species, (2) evaluating the risk of direct or adapted virus spillover infections in humans, and (3) examining the potential for Clade 2.3.4.4b H5N1 viruses to become transmissible among humans. |

| Results and Impact | Presented a talk as an invited speaker at the International Symposium on Poultry Health Challenges in Pakistan. Organized by the World Veterinary Poultry Association (WVPA-Pakistan Branch) at Serena Hotel Faisalabad, Pakistan. Poultry production continues to face several challenges caused by avian influenza, including: (1) virus evolution & antigenic diversity, (2) emergence of new virus variants, (3) co-circulation of multiple variants of same pathogen, (4) mixed infection of different viruses (immunosuppression), (5) maternally derived antibody interference, and (6) poor quality vaccines and sub-optimal vaccination practices. From these challenges, the topic of discussion and research drives optimal vaccination strategies to improve: (1) potency: a single dose to induce faster, stronger and durable immunity against multiple pathogens, (2) effectiveness: protect from clinical disease, reduced shedding and transmission, (3) affordability: cheap to produce and easy to deliver, (4) safety: no adverse impact to host or environment, (5) stability: retain efficacy for at least 1 year at indicated temperature, (6) DIVA: to allow differentiation between infected and vaccinated animals. Implementing new emerging vaccine approaches can: (1) enhance the efficacy, duration, and breadth of immunity, (2) reduce production losses, (3) improve cost-effectiveness, (4) improve productivity and economy, (5) improve animal welfare, and (6) reduce prevalence of viruses and protect public health (reduced virus prevalence = reduced zoonosis). |

| Results and Impact | Nearly two years on, the COVID-19 pandemic is still dominating the news and continues to cause concern for populations across the globe. However, UK poultry and wild bird populations are currently facing their own health threat. We are not the only ones that have faced lockdowns because of spreading viruses, UK poultry and captive birds have also faced a similar situation to protect them from avian influenza. Scientists at The Pirbright Institute are working to increase understanding of how genetic changes in influenza A viruses can impact disease spread, host responses to infection and the pathology associated with the disease. What is the avian influenza virus? Avian influenza viruses are Influenza A viruses that circulate and transmit amongst birds. The disease is what we commonly know as 'bird flu'. Influenza A viruses can infect a range of hosts, including humans and two subtypes H1N1 and H3N2 circulate as seasonal flu each winter in the UK. Avian influenza viruses are different to those that can infect humans in that they cannot easily infect humans and must change and adapt to do so. Aquatic birds are a natural reservoir for avian influenza viruses, these birds typically experience fewer clinical symptoms but can spread disease to domestic birds, particularly in the migratory season, between October and March. Avian influenza viruses are categorised as either highly pathogenic (HPAI) or low pathogenic (LPAI) and this categorisation is linked to the severity of disease in chickens. HPAI has a high mortality rate which can be up to 100%, other symptoms can include swelling of the head, death of cells in the comb and wattle, red discolouration of legs and feet and diarrhoea. HPAI causes disease in more organs than just those in the respiratory or gastrointestinal tracts like LPAI, which mostly presents as respiratory symptoms such as a snick (like a sneeze), a rattle in the chest (known as rales) and discharge from the eyes and nose. What is causing bird flu outbreaks in domestic birds now? We are currently in the normal migratory season of wild birds. In the spring and summer months, these birds spend their time breeding and raising their young in North-eastern Asia where they mix with other bird species which enables virus transmission and mutation. Then, when they migrate for the autumn and winter months, they shed virus in their faeces along the way. One of the migratory paths is across Northern Europe and this includes the UK. This year, in the UK, the first avian influenza outbreak was on 15 October and was discovered in captive aquatic birds. To date (17 December 2021) there have been 50 outbreaks in England, 1 in Wales and 2 in Scotland, this has resulted in over half a million birds being destroyed to control the spread of disease. Are there more outbreaks this year compared to other years? The number of outbreaks this year has been the most extensive ever. There have been over 50 outbreaks in the UK, compared to 26 outbreaks last year. Although it is hard to pin down the reason for this high number, we know it is not linked to the COVID-19 pandemic. The UK's response to the spread of avian influenza has been rapid, and from 29 November birds were required to be housed inside with additional biosecurity measures put in place such as foot dips and disinfecting clothing. Testing and surveillance of wild birds have shown that there is a high prevalence of the virus in these birds currently, and this is contributing to the spread of disease to farm and domestic bird populations. A more detailed look at the genetic make-up of these viruses shows that they are different to those from previous years. This is predicted to be as a result of the virus infecting multiple birds across a range of species, and this provides the perfect opportunity for the virus to evolve. Analysis of these genetic changes does not raise any alarm bells for increased transmission to humans, but they are likely impacting the spread and severity of disease in birds. What should we do if we find a dead bird or are concerned about bird health? If the public finds dead waterfowl birds they are encouraged not to touch them but to report them to Defra using the appropriate phone number that can be found on the website, also any other wild birds found dead in numbers of five or greater should be reported. What is Pirbright doing to tackle this virus? Researchers at Pirbright are attempting to enhance the control and detection of avian influenza in poultry populations as well as extend our basic knowledge about the virus in avian and mammalian hosts. The research groups led by Professor Munir Iqbal and Dr Holy Shelton are investigating how avian influenza virus strains originated from wild birds can rapidly adapt to cause disease outbreaks in poultry and gain the potential to infect humans. In addition, Professor Munir Iqbal is developing improved poultry vaccines that prevent virus replication and spread. These vaccines are particularly useful in countries where avian influenza is regularly found in the domestic poultry and the control and prevention of spread isn't easy, such as in the UK. |

| Primary Audience | Public/other audiences |
| Results and Impact | Following the news brief of our research outcomes for the general public and media was published on The Pirbright Institute and widely distributed through social media platforms including Facebook, Twitter, Linkedin. Pirbright scientists have discovered that infection with two strains of avian flu can lead to the emergence of a new virus strain with the potential to jump from birds to humans. Human cases of avian influenza are extremely rare but can occur if a person comes into very close contact with an infected or dead bird. The study shows that avian influenza virus strains H9N2 and H7N9 can share genetic information to create an H9N9 strain with the potential to cause more severe disease in poultry and pose a threat to human health. Avian influenza, also known as 'bird flu', is a type of influenza that spreads among birds. The UK faces a seasonal increase in the risk of avian influenza outbreaks which are associated with the migration patterns of wild birds. Avian influenza is found across the globe, and in countries where multiple strains circulate it is important to monitor the emergence of new strains. Low virulence H9N2 and H7N9 circulate in poultry in Asia but do not cause severe disease. However, they are known to swap genetic information which can result in the emergence of an H9N9 strain, which can cause severe disease. In collaboration with the Animal and Plant Health Agency (APHA), researchers at Pirbright discovered that the H9N9 strain was able to multiply significantly better in poultry cells, indicating the potential to cause more severe disease. They also discovered that it had a higher replication rate in human cells and could bind to these cells better than H9N2. The H9N9 strain can infect and transmit between ferrets highlighting the potential to cause disease in humans. The study, published in the Journal of Virology, shows that strains already circulating in poultry populations can exchange genetic material, leading to the creation of new strains. This increases the risk of the virus jumping from avian hosts to humans and other mammals. The study concludes that H7N9 and H9N2 viruses circulating in the same regions pose a pandemic threat, which demonstrates the need for constant monitoring for the emergence of new virus strains. Professor Munir Iqbal, Head of the Avian Influenza Group at Pirbright said: "This is the first study to show that infection with circulating H9N2 and H7N9 influenza viruses could create new virus strains such as H9N9 that cause more disease in poultry and pose a greater risk to human health. If a host is infected with two different strains, there is always a chance that they will swap genetic material to create a new strain. When this happens, it could lead to many outcomes, for example, the virus becoming more or less able to cause disease in a host, or a virus acquiring the ability to jump between hosts. This leads to viruses that primarily cause disease in animals having the ability to infect humans, which is what we have observed in this study. More research is needed to determine which avian flu viruses could combine and pose a threat to poultry and human health." This study was supported by grants funded by the UK Research and Innovation Biotechnology and Biological Sciences Research Council under Newton Fund UK-China-Philippines-Thailand Swine and Poultry Research Initiative and Zoonoses and Emerging Livestock Systems (ZELS) with grants from FCDO and Dstl. The work was also funded by the GCRF One Health Poultry Hub and Defra (UK, including the Devolved Administrations of Scotland and Wales). |

In the UK, every day now, two or three new premises have been testing positive for bird flu. If they do, their flocks are culled and over 50 million birds culled in Europe this year and a similar number in North America. There is a need for an improved disease control strategies against these viruses. just culling of infected and at risk will not reduce viruses prevalence and spread, because virus in circulating in wild birds. |

| Results and Impact | Internal seminar presented at The Pirbright Institute, sharing the achievements and current ongoing research being performed within the Avian Influenza Virus and Newcastle Disease Virus Group to other colleagues throughout the site. Poultry production continues to face several challenges caused by avian influenza, including: (1) virus evolution & antigenic diversity, (2) emergence of new virus variants, (3) co-circulation of multiple variants of same pathogen, (4) mixed infection of different viruses (immunosuppression), (5) maternally derived antibody interference, and (6) poor quality vaccines and sub-optimal vaccination practices. From these challenges, the topic of discussion and research drives optimal vaccination strategies to improve: (1) potency: a single dose to induce faster, stronger and durable immunity against multiple pathogens, (2) effectiveness: protect from clinical disease, reduced shedding and transmission, (3) affordability: cheap to produce and easy to deliver, (4) safety: no adverse impact to host or environment, (5) stability: retain efficacy for at least 1 year at indicated temperature, (6) DIVA: to allow differentiation between infected and vaccinated animals. Implementing new emerging vaccine approaches can: (1) enhance the efficacy, duration, and breadth of immunity, (2) reduce production losses, (3) improve cost-effectiveness, (4) improve productivity and economy, (5) improve animal welfare, and (6) reduce prevalence of viruses and protect public health (reduced virus prevalence = reduced zoonosis). |

| Results and Impact | A news story was published to increase the awareness of Zoonotic diseases and their impact on public health, food security, the economy and the environment. This was publicised at The Pirbright Institute webpage and One Health Poultry Health webpage and distributed wildly on social media including Facebook, Twitter, In Share. On World Zoonoses Day, Pirbright's Professor Munir Iqbal and Dr Joshua Sealy consider 600 years of developing technology to fight infectious diseases: The history of human and animal immunisation against infectious disease begins with the Chinese practice of variolation in the fifteenth century. Here, infectious material was taken from one patient and inoculated into a non-infected patient to initiate a mild but protective infection. Roughly 200 years later, Edward Jenner transformed the field of immunology by developing the world's first vaccine which involved immunising patients against smallpox using the closely related cowpox. Fast-forward another 200 years and the application of vaccines had transformed. On 6 July 1885, now celebrated as World Zoonoses Day, Louis Pasteur successfully administered the first vaccine against rabies - and within decades myriad other diseases had also been tackled effectively, including diphtheria, tetanus, anthrax, cholera, plague, typhoid, tuberculosis, measles, mumps, rubella, and polio. Many of these pathogens had been infecting humans for years, and continue to do so where vaccines are not deployed. Now, in the 21st century, vaccine research is undergoing another seismic shift. In 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the virus that causes COVID-19), emerged in humans which is believed to have originated in animals (known as zoonoses). It has since developed into the devastating COVID-19 pandemic and in doing so it triggered an urgent need to develop vaccines to control a virus that represents a growing problem at the human-animal interface. Pathogen evolution: Broadly speaking, humans have a naïve immune system to the many pathogens that exclusively circulate within animal reservoirs, including livestock. Most pathogens have evolved to infect specific animal species, which means that a significant barrier exists that prevents animal pathogens from causing disease in humans. However, a portion of these pathogens, including influenza viruses and coronaviruses, have the capacity to evolve such that they can overcome these barriers and be successful, especially as there is no prior immunity in the human population. This extraordinary ability to evolve also means that these pathogens have the potential to overcome vaccines. The application of vaccines and vaccine technology must progress to meet the challenge of zoonotic viruses. Vaccine variety: An impressive diversity of vaccine technologies is currently employed or in development to combat pathogens circulating in humans and animals. A vaccine needs to be effective at eliminating or reducing disease, but the diversity of pathogens means vaccines sometimes need to be equally diverse and must cater to specific challenges. Traditional inactivated pathogen vaccines are generated by 'killing' a pathogen so that it can be safely administered for immunisation. Subunit vaccines are vaccines that comprise only a fragment of the target pathogen which can be administered to generate an immune response exclusively to that fragment. Both technologies elicit protective antibody responses and have been successful for an exceptionally long time against a variety of pathogens. However, an antibody response does not provide sufficient protection against all pathogens that continually change their shapes to evade vaccines. Live attenuated vaccines typically use infectious pathogens that are modified to prevent them from causing disease but can still trigger an immune response similar to their naturally occurring counterparts. These vaccines are useful because as well as an antibody response, they can induce a cellular immune response, which targets conserved parts of the pathogens that remain the same across different strains. This means live attenuated vaccines are more effective at protecting against mutations that could allow the pathogen to escape vaccine immunity and they provide better protection against multiple pathogen strains. New vaccine technology: Viral vector vaccines are vaccines that comprise the 'backbone' of a virus that doesn't cause disease in the host animal, which expresses a piece of the target pathogen that induces an immune response. Most licensed viral vector vaccines are in use in animals, with only a single vectored vaccine (against the Ebola virus) being licensed for humans prior to the SARS-CoV-2 pandemic. Viral vector vaccines evoke a strong immune response that is specific to the pathogen, making it effective and long-lasting. DNA/RNA vaccines contain genetic material that codes for a piece of a pathogen, which the host cells process to elicit an immune response. Several mRNA vaccines are in use against SARS-CoV-2 and they are cost-effective, safe, and produced using chemicals synthetically and not from cell culture systems. As such, we now have the capacity to carefully select the target of our vaccines and the nature of the desired immune response. The importance of vaccines was brought into focus once again with the SARS-CoV-2 pandemic - and, going forward, the need for our growing arsenal of vaccines will only increase with the needs of humanity. Nutrition: As the human population increases so do its need for nutrition. A major source of human nutrition is animal-derived; thus, the population of farmed animals increases. Wild habitats are encroached upon to provide for the increasing population of farmed animals, and this facilitates interaction between farmed and wild animals. Consequently, we develop a tractable route for zoonotic diseases to enter the human population. Finally, the need for human nutrition is also met through the acquisition of wild animals. There is evidence to suggest that the West African Ebola virus epidemic was preceded by the capture of wild animals for human consumption. Likewise, SARS-CoV-2 is believed to have originated in wild animals. Zoonotic diseases clearly have far-reaching impacts. Humans and animals directly suffer pathogen-related sickness and death, and global economies incur significant losses. The current SARS-CoV-2 pandemic is a clear example of this - while avian influenza and several other emerging and re-emerging viruses carrying zoonotic infection potential circulating in farmed and wild birds are a constant reminder that the next pandemic could be around the corner. Written by Professor Munir Iqbal and Dr Joshua Sealy, members of the Avian Influenza Virus group at Pirbright. |

| Results and Impact | This discussion was due to current enormous global spread of bird flu and widespread poultry outbreak has generated unprecedented opportunities for the virus to jump to humans and potentially even mutate to better spread between people. Since the Live bird markets have been identified as key factors in the spread, persistence and evolution of avian influenza viruses,. Therefore, there is an increased risk to public at the live birds markets and how these risks can be reduced to increase food safety, security and public health. |
