"CHICAGO - Scientists in Britain have found they can partially protect chickens from bird flu infections by editing their genes, signaling a new potential strategy to reduce the spread of the deadly virus.
Highly pathogenic avian influenza, known as bird flu, has spread to new corners of the globe since 2022, wiping out millions of poultry birds and sending egg and turkey prices soaring.
Experts warn that mutations could potentially threaten a human pandemic, though the current strain has not caused significant disease in people.
Researchers said they used the gene-editing tool CRISPR to make specific changes to a gene called ANP32 that is essential to support flu viruses inside chickens' cells. CRISPR is a type of molecular "scissor" technology that scientists can use to edit DNA."
