Study Notes
Disinfectants, Antiseptics, and Preservatives
- Disinfectants, antiseptics, and preservatives are chemicals that can destroy or inhibit the growth of microorganisms.
- Destruction of microorganisms implies a zero survival rate, meaning the end of microbial life.
- Control of microorganisms can be achieved through sterilization, disinfection, or preservation.
Disinfection Levels
- Intermediate level disinfection: destroys all vegetative bacteria, including Mycobacterium tuberculosis, but may not include some viruses and fungi, and has limited or no sporicidal activity.
- Low level disinfection: destroys most vegetative bacteria, some fungi, and some viruses, but does not include spores and more resistant microorganisms.
Preservatives in Sterile Products
- In sterile products, such as eye drops and multi-dose injections, preservatives should kill any microbial contaminants introduced accidentally during use.
