What is a bacteriophage?
A bacteriophage (also known as a phage) is a type of virus that infects and replicates within bacteria. Bacteriophages are composed of a nucleic acid molecule (DNA or RNA) surrounded by a protein coat, and they are specific to certain types of bacteria.
Bacteriophages are found in many different environments, including soil, water, and the human gut. They play a significant role in the natural balance of bacteria in these environments and can be used as a tool to control bacterial infections in humans.
How do bacteriophages work?
Bacteriophages have been studied for their potential use as antimicrobial agents, and some have been developed into phage therapies for the treatment of bacterial infections that are resistant to traditional antibiotics.
