Phages, towards a targeted alternative to antibiotics

With the rapid development of antibiotics in the 1930s, phage therapy -- using viruses known as bacteriophages or phages to tackle bacterial infections -- fell into oblivion. But as the current rise in antibiotic resistance is making it increasingly difficult to treat bacterial infections, phage therapy is once again sparking interest among physicians and scientists -- although it remains complex in practice because of the great diversity and specificity of phages.
