Study Notes
Halogens as Disinfectants and Antiseptics
- Halogens are effective against a wide range of microorganisms, including gram-positive and negative bacteria, fungi, and viruses.
- They can be used as both disinfectants and antiseptics, depending on the context.
Mechanism of Action
- Halogens affect the permeability of the microbe cell membrane.
- They dissolve lipids in the cell wall and membrane, disrupting the structural integrity of the microbe.
- Halogens also denature microbial proteins, interfering with their function and ultimately leading to the destruction of the microbe.
- Additionally, they can destroy DNA and microbial proteins, further contributing to their antimicrobial effects.
Uses of Halogens
- Halogens can be used as disinfectants, effective against a broad range of microorganisms.
- They can also be used as antiseptics, with some halogens being more effective in this context than others.
- Specifically, halogens work well against anaerobic bacteria, and can be used as either a disinfectant or an antiseptic in these cases.
