Washington: Scientists have developed a new biosensor that can detect antibiotic resistance in bacteria.This new technology is a preliminary step in identifying and fighting superbugs, a major public health concern that has led to more deaths than AIDS in the United States in recent years. The technology is the result of collaboration between Dr. Vitaly Vodyanoy at Auburn University and the Keesler Air Force Base with funding from the United States Air Force.Louis Pasteur and Robert Koch first characterized antibiosis, the ability for a chemical to kill bacterial cells, in 1877. Since then, the medical and biochemical communities have made great advances in the treatment of bacterial infections. These advances have helped reduce childhood mortality and have contributed to the population growth of the 20th Century. However, natural selection has allowed antibiotic resistant bacteria to flourish and propagate, and continued exposure has lead to the evolution of "superbugs" that are resistant to multiple types of antibiotics.
