AI Insight
The human body contains approximately 38 trillion bacteria, most of which are harmless or beneficial to health. A small fraction of these bacteria can cause serious illness, particularly when they develop antibiotic resistance. The article discusses the potential use of bacteriophages (viruses that infect and kill bacteria) as an alternative treatment approach through the development of phage libraries.
Why it matters
As antibiotic resistance becomes an increasingly critical global health threat, phage therapy represents a promising alternative or complementary approach to treating bacterial infections. Creating libraries of bacteria-killing viruses could provide targeted treatments that spare beneficial bacteria while eliminating harmful pathogens.
Understand the Science
An estimated 38 trillion bacteria live in the human body—and only a small fraction are harmful to our health. However, the harmful ones can cause serious illness, especially when they develop resistance to antibiotics.
