Bacteriophage, a virus that infects bacteria, and its role in phage therapy
Definition
Bacteriophages are viruses infecting bacteria (~10^31 on Earth) with applications in phage therapy (antibiotic alternative), molecular tools (M13 phage display, lambda cloning), and CRISPR systems derived from phage defense mechanisms. In molecular biology research, bacteriophage plays a crucial role in experimental design, data interpretation, and understanding fundamental biological processes. Researchers working with bacteriophage apply computational tools and molecular techniques to investigate its structure, function, and interactions within cellular systems.
In Practice
Virology is central to molecular biology research and clinical applications. Key use cases include:
- Designing primers for phage genome amplification and sequencing
- Analyzing phage-host interaction dynamics using genomic tools
- Designing phage therapy cocktails for antibiotic-resistant infections
- Characterising phage structural proteins using proteomics workflows
- Engineering phages for targeted bacterial killing in therapy
- Using phage display libraries for antibody discovery
