In this groundbreaking study, Northwestern University researchers have reached a significant milestone in the realm of combating deadly pathogens by engineering viruses. The focus of their innovative approach lies in the meticulous modification of the DNA of a bacteriophage—a type of virus specialized in infecting bacteria. The researchers harnessed this modified DNA to target and eliminate Pseudomonas aeruginosa (P. aeruginosa), a notorious bacterium known for its high resistance to antibiotics and lethality. This breakthrough marks a pivotal step towards developing targeted therapies to address antibiotic-resistant bacteria, offering a potential solution to a critical global health challenge.
