What is the primary distinction between 'cidal' and 'static' agents in controlling microbial growth?
What is the primary distinction between 'cidal' and 'static' agents in controlling microbial growth?
- 'Cidal' agents are used only for bacteria, while 'static' agents can be used for viruses.
- 'Cidal' agents inhibit growth, while 'static' agents kill microorganisms.
- 'Cidal' agents can be harmful to living tissue, while 'static' agents cannot.

Study Notes
Controlling Microbial Growth
- Microbial growth control aims to stop or prevent microbial growth.
- This is achieved through two methods: killing microorganisms or inhibiting their growth.
- Agents that kill microorganisms are called "cidal" agents.
- Agents that inhibit microbial growth but don't kill them are called "static" agents.
- For example, bactericidal agents kill bacteria and bacteriostatic agents inhibit bacterial growth.
- There are three main types of agents used for microbial growth control: physical, chemical, and chemotherapeutic.
Physical Agents
- Used exclusively on external objects.
Chemical Agents
- Used on inanimate objects and body surfaces.
Chemotherapeutic Agents
- Primarily used inside the body.
