still a few year off, obviously

Scientists from Nanyang Technological University (NTU) have re-engineered a common bacterium, turning it into a “suicide bomber” against a superbug which is naturally resistant to a wide range of antibiotics.

For the first time, scientists are able to modify a harmless strain of Escherichia coli (also known as E. coli) found naturally in the human digestive system to seek out and kill other dangerous bacteria.

The targeted superbug, known as Pseudomonas aeruginosa, is a bacterium which causes infections, such as upper respiratory tract infection, gastrointestinal tract infection and urinary tract infection.

The biochemically engineered E. coli, upon detection of the other bacterium, will generate “killing molecules” within them, and will self-destruct, releasing the molecules to kill the aeruginosa. These “killing molecules” are deadly for the superbug, but harmless to the human body.
