Bird flu case has caused serious losses to many poultry owners and be bothered with vaccinations affairs. But with genetic engineering technique, scientists has successfully developed a chicken that don’t not spread bird flu.
Scientists have developed a method to limit the spread of bird flu with the help of genetically modified chickens that do not spread bird flu.
Rooster chicken called GM (Genetically Modified) chicken has an additional DNA which inserted into the genome thus produce a molecule size bait that inhibit the replication of influenza virus and prevent transmission to the entire flock of chicken.
Scientists believe that this breakthrough could eventually lead to the creation of the GM poultry, swine and other GM livestock so it resistant to various infectious diseases. Scientists also said that this breakthrough could help reduce the risk of virus transmission to humans.
While many consumers are scared and anti-GM crops, scientists believe that these GM chickens that immune to various infections can be accepted for reasons of concern about transmission of infectious diseases in humans.
According to Dr Laurence Tiley, Senior Lecturer in Molecular Virology from the University of Cambridge, resistance to the disease is clearly a huge benefit for animal welfare and public health.
GM chickens are created by adding a synthetic DNA fragment into the chromosome, which causes chickens to produce short RNA, the genetic molecule that is used by influenza virus. These pieces of RNA act as decoys by locking to the enzyme used by the bird flu virus to copies itself.
Dr Tiley hopes this bait work against all bird flu strains and will complicate this virus to escape from the effects of bait.
“If you have a GM chickens that are resistant to the bird flu virus then in theory you are no longer need to bother with a vaccination,” said Dr Tiley.
Professor Helen Sang from The Roslin Institute at the University of Edinburgh, said that the results achieved so far are very encouraging. This study has been published in the journal of Science.
