Chapter 11, Episode 46

Microbial control focuses on reducing microbes to safe levels rather than eliminating them entirely in most situations. Key terms include sterilization (complete removal), disinfection (reducing microbes on surfaces), antisepsis (reducing microbes on living tissue), and decontamination (mechanical removal). Whether microbes cause infection depends on microbial load and host defenses, and control methods aim to lower risk rather than achieve absolute sterility. Understanding the difference between microbicidal and microbistatic approaches, along with microbial resistance, helps determine the appropriate level of control in healthcare and everyday life.
