Study Notes
Definitions of Sterilization and Disinfection
- Sterilization: The process of completely destroying all forms of microbial life (bacteria, viruses, fungi, and highly resistant spores). It's crucial for sterile equipment, surfaces, and materials.
- Disinfection: The process of reducing or eliminating most pathogenic microorganisms (excluding bacterial spores) from non-living surfaces. It significantly lowers the risk of infection.
Methods Used
- Sterilization: Achieved through physical methods (autoclaving, dry heat, filtration) and chemical sterilants (ethylene oxide gas, hydrogen peroxide).
- Disinfection: Removes most pathogens but doesn't eliminate all microbial life.
Goals
- Sterilization: The goal is absolute sterility (no microbial life).
- Disinfection: To reduce the risk of infection/contamination, not complete elimination of all life.
Importance in Microbiology and Medical Fields
- Sterilization & Disinfection are Essential for:
- Infection control
- Aseptic procedures
- Food production
- Water treatment
- Proper microbial control protects against the spread of infectious diseases and ensures safe handling of materials.
- Critical in: laboratories, healthcare, and industrial settings.
Prevention of Infections (Healthcare)
- Proper sterilization & disinfection crucial in healthcare settings for preventing infections.
