In a major advance against drug-resistant pathogens, researchers from Monash University and The Alfred Hospital engineered bespoke bacteriophage cocktails targeting multidrug-resistant bacterial strains such as Enterobacter cloacae. These therapies harness viruses specific to the bacteria, offering precision treatment options in the antimicrobial resistance crisis. Studies published in Nature Microbiology reveal how these phage products provide an effective alternative to traditional antibiotics, potentially transforming infectious disease management.
