UK study finds some species of seabirds are showing signs of developing immunity to avian influenza
The Country Smallholder
|December 2023
The eight-strong FluMap consortium, headed by the world-leading research team at the Animal Plant Health Agency (APHA), has developed laboratory tools that can dissect the immune response in birds that have been exposed to avian influenza viruses in their lifetime.
-
Preliminary investigations in a small sample size of some species of seabird, including Northern gannets and Shag, revealed specific immunity to H5N1 showing exposure and recovery in a proportion of birds. However, avian influenza viruses are prone to change and so antibody levels will likely decline over time with next year's offspring not guaranteed to be immune suggesting there are no great population-level benefits yet.
Scientists hope to look at the effect of antibodies on infection, to better predict the emergence of new viruses with different protein combinations in the future, allowing experts to stay one step ahead to safeguard animal and human health, given 60% of new human diseases originate in animals.
