Scientists Create Deadlier TB Strain By Accident

Makarand writes "BBC News is reporting that Scientists at the University of California (Berkeley, U.S.) accidentally created a hyper-virulent form of the Tuberculosis bacterium while trying to alter its genetic structure to make it less deadly. The mutant form of the super-bug could multiply more quickly and also had the unexpected effect of undermining the body's own immune response against Tuberculosis."
