There has been much in the press in recent years about the looming post antibiotic era, and rightly so, the overuse and misuse of antibiotics has led the rapid evolution of bacteria that are resistant to multiple antibiotics.
To that end a report by the National Institute of Allergy and Infectious Diseases called for an expansion of antimicrobial strategies.
One of those strategies is the use of viruses that specifically target bacteria. Known as bacteriophages they were first studied more than a century ago but were largely forgotten with the advent of antibiotics.
Big questions remain and much research still needs to be done, but this century old discovery could well form a new arsenal against a constantly evolving problem.
Here the The Scientist Magazine takes a look at the history, the current state of the technology and its possible benefits.
