Scientists have developed the first genetically modified (GM) chicken, engineered to prevent the spread of the H5N1 avian influenza virus, and in the process have sparked a renewed debate about the development of biotechnology.
UK scientists have created the world's first genetically modified chickens that do not spread bird flu.
Writing in Science journal, the team says their work demonstrates it is possible to create a variety of GM farm animals resistant to viral diseases.
The research team inserted an artificial gene into chickens; this introduces a tiny part of the bird flu virus into chicken cells.
These birds become infected but render the virus harmless to other poultry.
The team believes that the genetic modification they have introduced is harmless to the chickens and to people who might eat the birds.
Professor Helen Sang of Edinburgh University told BBC News that genetic modification is potentially a much better way of protecting against diseases than vaccination because the GM technique works even if the virus mutates.
"It will protect a whole flock from avian influenza infection. This is really exciting because bird flu is a real challenge to poultry production and if it were introduced to poultry breeding it would protect our large scale production flocks from avian inlfuenza," said Professor Sang.
The team believes that the genetic modification they have introduced is harmless to the chickens and to people who might eat the birds.

A place where I get lunch told me pigs used to be red meat and were modified to the white meat to compete with chicken. So they been playen with the food for some time.
hope they put a label on it and let us know. thats too much genetic minipulation to work out a virus. they may have just made space for a new something to grow...
