Mutant H9N2 avian influenza viruses show enhanced zoonotic potential

Research led by The Pirbright Institute has shown that mutant influenza A(H9N2) viruses isolated from Pakistan are able to escape immune responses and adapt to infect humans. This could result in reduced vaccine efficiency in poultry and the possibility of human outbreaks. The researchers report in Emerging Infectious Diseases the discovery of small changes to […]

Recombinant viral vector for poultry vaccination

Researchers at The Pirbright Institute have developed a new recombinant viral vector-based vaccine that is effective against both Marek’s disease (MD) and infectious bursal disease (IBD). Their study is published in npj Vaccines. Many poultry vaccines currently use a modified herpesvirus of turkeys (HVT) to induce protection. Although these vaccines are effective when used alone, […]

Pandemic potential of H9N2 avian influenza viruses studied

Researchers have identified the molecular mechanisms that enable H9N2 viruses – the most common type of avian influenza virus – to infect humans, helping improve risk assessments for its potential to cause pandemic. Although H9N2 viruses are considered less pathogenic than some types of avian influenza virus, they still cause significant losses for the poultry […]
