# Bacteria Hunters (DD-309)

> 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.

- **DD-309-F02**: They inject genetic material. _(Write-up · Exhibit B (Inject))_

## Write-up

Bacteriophages are viruses that only infect bacteria. They burst bacteria from the inside to release new copies.

1. **Viruses**: Phages are viruses of bacteria.
2. **Inject**: They inject genetic material.
3. **Hijack**: They hijack the cell.
4. **Burst**: The cell bursts to release phages.
5. **Therapy**: Phage therapy is studied.

### Transcript

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!
