LONDON (Reuters) – British scientists are developing genetically engineered chickens designed to fully withstand the flu with a new approach to preventing a deadly pandemic in humans.
"The first generation of modified chickens will hatch later this year at the Roslyn Institute of Edinburgh University in Scotland," said Wendy Parkley, Professor of Virology at Imperial College. of London and co-chair of the project.
The DNA has been modified for birds with the help of a new gene modification technique called Cresper.
In this case, the "adjustments" are made to remove some of the protein that the influenza virus usually supports, making the chicken completely resistant to the flu.
Barkley said the idea was to produce poultry that could not catch the flu and was "a barrier between wild birds and humans".
Global experts in health and infectious diseases consider the risk of a human influenza pandemic as one of their main concerns.
The Spanish flu pandemic of 1918 killed about 50 million people.
The biggest fear right now is that a deadly strain of bird flu is passing from humans to wild birds, and then turns into an airborne epidemic that can easily be transmitted between humans.
"If we can prevent the flu virus from passing wild birds to chickens, we will stop the pandemic that is the source," said Barkley.
Poultry producers' concerns about public acceptance have been a major impediment to this approach.
"People are eating foods from farm animals that have undergone changes over decades of traditional hybridization," she said. "But they could be worried about the consumption of genetically modified foods".
