Researchers at Imperial College London and the University of Nottingham have found a novel way of killing harmful bacteria [bbc.com] that cause infection — setting predator bacteria loose to eat the harmful ones.
Experiments showed a dose of Bdellovibrio bacteriovorus acted like a "living antibiotic" to help clear an otherwise lethal infection.
The animal studies, published in Current Biology [cell.com], suggested there would be no side effects.
[...] Dr Michael Chew, from the Wellcome Trust medical research body, said: "It may be unusual to use a bacterium to get rid of another, but in the light of the looming threat from drug-resistant infections the potential of beneficial bacteria-animal interactions should not be overlooked.
"We are increasingly relying on last-line antibiotics, and this innovative study demonstrates how predatory bacteria could be an important additional tool to drugs in the fight against resistance."
