While it doesn’t seem to be wiping out any populations yet, a gene known as NDM-1 (New Delhi metallo-beta-lactamase) has been identified in the New Delhi water supply and classified as a superbug.
The gene’s danger lies in its capacity to make many other bacteria resistant to almost all antibiotics, making them the actual superbugs. Indian health officials have disputed NDM-1’s origin in India, but not the fact that it exists in the New Delhi water supply. The British study which identified the gene also cautioned people against seeking surgery in India, much to the displeasure of the same Indian health officials. The study’s authors also expressed a concern that NDM-1 had the capability to spread throughout the world.
