Bacteria Hunters

Short answer: Bacteriophages, or phages, are viruses that infect bacteria. A phage attaches to a bacterium and injects its genetic material, hijacking the cell to make new phages.

Enzymes then break down the cell wall, the bacterium bursts and the new phages are released. Because they destroy bacteria this way, phages are studied as a possible antibacterial therapy, called phage therapy. The footage is an animation of phages attacking a bacterium.

Video transcript: Bacteria Hunters: Bacteriophages Are Viruses That Only Infect Bacteria

Bacteriophages, or phages, are viruses that specifically infect bacteria. They attach to a bacterium, inject their genetic material, and hijack the bacterial machinery to produce new phages. As new phages accumulate, they release enzymes that break down the bacterial cell wall, causing the bacterium to burst and release the new phages. This cycle effectively destroys bacteria from the inside out, making phages a potential tool for antibacterial therapy. NOW YOU KNOW!
