Yet eventually these salmon can escape into the wild and cause unpredictable ecological disruption. The DNA of a virus can pass through even the gut of mice and find its way into every kind of cell, creating genetic disturbances including cancer, a disease that more than thirty years of medical research has been unable to find the cure. A gene can replicate indefinitely, spread and combine. We have no means to stop this process but must let it pass on in its invisible ways. When a massive load of virus genes combines with wild relatives it can result in creating super viruses that can lead to deadly diseases.
Vectors used in genetic engineering can infect a wide range of species.
It's a bad science and a bad business making dangerous alliance. Along with ecological disasters, the year 1997 can be rightly named a year of the holocaust of farm animals. Outbreaks of infectious diseases among farm animals all over the world has caused researchers to worry that we are due for another global epidemic, primarily owing to the over use of antibiotics. Two strains of E. coli as well as Staphylococcus bacteria now contaminate meat, poultry and diary products. Genetic engineering can greatly compound this problem.
