LONDON (Reuters) – British scientists are developing genetically modified chickens and are designed to fully withstand the flu thanks to a new approach aimed at preventing a deadly pandemic in humans.
Wendy Parkley, professor of virology at Imperial College London and co-chair of the project, said that the first generation of modified chickens would hatch later this year at the Roslyn Institute of the University of Toronto. Edinburgh, Scotland.
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 flu virus usually depends on, 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 being passed from humans through wild birds to an airborne epidemic that can easily be passed between humans.
"If we can prevent the flu virus from passing wild birds to chickens, we will stop the outbreak 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 (…) but they may worry about the consumption of the animals. genetically modified foods, "she said.
