‘Living medicine’ helps make toxic ammonia breakthrough

Using genetically modified bugs to prolong life was 'fanciful' until recently, says scientist

A "living medicine" made from genetically modified bugs has prolonged the lives of animals with severe metabolic disease in a landmark test of the treatment.

Researchers created the medicine by making a common strain of bacteria mop up excess ammonia in the body. High levels can be fatal for people with liver damage and rare genetic disorders.
