Scientists look to viruses to fight bacteria

Scientists are re-exploring "phage therapy," the use of viruses to kill antibiotic-resistant bacteria, according to The Washington Post.

Why it matters: Antibiotic resistant bacteria pose one of the biggest threats to human health, according to the World Health Organization. Bacteriophage therapy could be another option as resistance to existing antibiotics grows because of the large number of phages on Earth (in excess of 10 million trillion trillion), each likely to target a different species of bacteria.
