laboratory strains

Laboratory strains are specific, well-characterized versions of microorganisms, such as bacteria, viruses, or fungi, that scientists use for research and testing. They are bred and maintained under controlled conditions to ensure consistency and reproducibility in experiments. Because their genetic makeup is stable and documented, laboratory strains provide a reliable foundation for studying biological processes, developing medicines, or testing treatments. They are distinct from wild or naturally occurring strains, which may have more genetic variability, making laboratory strains essential tools for scientific precision.
