Taking a leaf out of a microbe’s book
A species of marine bacteria, called Vibrio alginolyticus, possesses a natural ability to seek out food as quickly as possible, which could inspire novel human therapies using Escherichia coli, suggests an international research team lead by the University of Edinburgh, UK. The study found that the ocean microbes that travel fastest change direction most often, so that they could target the nutrients they need more precisely. They also found that the closer V. alginolyticus were to the food, the faster they swam. The scientists believe that E. coli could be engineered to include the genes that give V. alginolyticus such abilities, which can then be used to deliver drugs precisely.
