Questions and Answers

Which statement accurately distinguishes between cidal and static agents?

Cidal agents inhibit the growth of microorganisms without killing them.

Cidal agents directly kill microorganisms, while static agents inhibit their growth. (correct)

Static agents kill microorganisms instantly upon contact.

Static agents can be used to prevent infections inside the body.

What is the primary role of chemical agents in controlling microbial growth?

They can only be applied to biohazardous materials.

They are used exclusively on living organisms.

They are effective only when combined with physical agents.

They can be used on both inanimate objects and body surfaces. (correct)

Which of the following best describes the use of physical agents in microbial control?

Physical agents are dedicated for use on objects outside the body. (correct)

Physical agents are primarily used to sterilize food products.

Physical agents are effective for killing pathogens inside the body.

Study Notes

Controlling Microbial Growth

Microbial growth is inhibited or prevented.
This is achieved in two ways: killing microorganisms or inhibiting their growth.
Agents used for control are categorized as cidal (killing) or static (inhibiting growth).
Examples include bactericidal (killing bacteria) and bacteriostatic (inhibiting bacterial growth).
Control methods use different types of agents.

Types of Control Agents

Physical agents: Used only on objects outside the body.
Chemical agents: Used on inanimate objects and body surfaces.
Chemotherapeutic agents: Primarily used inside the living body.
