New research uncovers poultry resistant to AI

Some chickens are almost completely resistant to a serious strain of avian influenza, new research has shown. The study, carried out at the Pirbright Institute, found birds that carried the strain of avian influenza but were genetically resistant to the disease only shed the virus through their respiratory tract and for a limited period of time. The researchers discovered that this was the only relevant means of spreading the virus and that resistant birds were therefore completely unable to ini
