OIE calls for increased surveillance of avian influenza

The World Organisation for Animal Health (OIE) is urging countries to maintain their surveillance efforts and to continue timely reporting of avian influenza, as outbreaks in poultry and wild birds intensify. Since the beginning of May 2021, outbreaks of high pathogenicity avian influenza (HPAI) have been confirmed in more than 40 countries from different regions […]

Influenza, Still a Major Threat – New International Report on Current Research

The STAR-IDAZ International Research Consortium on Animal Health has published an independent report, (available in the reports section of this website – here) to comprehensively review the research on animal influenza viruses, that has been published in the last five years, including studies on virology, pathogenicity, epidemiology, prevention and control. As well as reviewing recently […]

Improved poultry influenza vaccine provides rapid protection

A vaccine developed by researchers at The Pirbright Institute triggers a rapid immune response which protects chickens against signs of disease and reduces virus shedding. The researchers say the vaccine would also be easier and less costly to produce than the traditional influenza vaccines made in chicken eggs. Many poultry influenza vaccines protect birds from […]

Avian influenza: genetic markers identified that could guide future surveillance

Researchers at The Pirbright Institute have identified the genetic markers on avian influenza viruses that could help the viruses to jump the species barrier and cause disease in people, in collaboration with other members of the One Health Poultry Hub. Co-investigators Professor Munir Iqbal and Dr Joshua Sealy worked with scientists at Imperial College London, […]

Adaptability of avian influenza viruses poses threat to poultry

New insights from a study of the 2016/2017 avian influenza outbreak in Eurasia show how highly pathogenic avian influenza viruses – which are likely to cause severe disease in chickens – can be transmitted from wild migrating bird populations to domestic flocks and back again. These viruses can readily exchange genetic material with other low […]

Avian influenza: recombinant antibodies reduce symptoms and virus shedding in chickens

Scientists at The Pirbright Institute have engineered synthetic antibody molecules that can be administered to poultry to reduce the symptoms of influenza, as well as decreasing the amount of virus they shed into the environment. These results suggest that there is potential for their use as immunotherapy treatments to reduce the burden of influenza in […]

Genetic engineering speeds up poultry vaccine development

Scientists at The Pirbright Institute have used genetic engineering to develop a vaccine that protects birds against both Marek’s disease and avian influenza. They say the process is faster and more efficient compared to previous methods, which will allow poultry vaccine producers to rapidly update vaccine strains in order to keep up with virus evolution. […]

Avian influenza: study identifies high risk poultry trading practices in Vietnam

Scientists at The Pirbright Institute have found that the transmission of avian influenza viruses in Vietnam is influenced by the structure of live poultry trading networks. Their work has identified the groups that are most likely to employ trade practices that impact the risk of infection in chickens, which could better inform vaccination strategies in […]

A single Influenza A virus protein can increase period of infection

Research led by scientists at The Pirbright Institute has shown how an Influenza A virus (IAV) accessory protein, PB1-F2, is able to shut down two pathways of the chicken immune response to increase the length of time the virus can be transmitted. The researchers say that the majority of avian IAV isolates are able to […]

Launch of the ‘One Health Poultry Hub’

The Royal Veterinary College (RVC) has announced the launch of the UKRI GCRF One Health Poultry Hub. The RVC is the lead organisation, with partners in Asia, Australia and Europe. Funded by the Global Challenges Research Fund (GCRF) of UK Research and Innovation (UKRI), this interdisciplinary Hub will address the need to meet rising demand […]
