DISINFECTION
93
application of a liquid antimicrobial chemical to skin or living tissue to inhibit or destroy microorganisms.
ANTISEPSIS
94
- uses water, detergent, and some mechanical action such as scrubbing with a gloved hand or brush.
CLEANING
95
DECONTAMINATION FOR LIVING TISSUES
- CHEMICAL - RADIATION - THERMAL - FILTRATION
96

97
FACTORS AFFECTING DISINFECTION:
NUMBER OF MICROORGANISMS LOCATION OF MICROORGANISMS INNATE RESISTANCE TO DISINFECTANT PRODUCT FACTORS SURFACE TOPOGRAPHY BIOFILM CONCENTRATION & POTENCY OF THE DISINFECTANT PHYSICAL & CHEMICAL FACTORS APPROPRIATE CONTACT TIME
98
- Aggregated, clumped and abundant microorganism are more difficult to inactivate.
NUMBER OF MICROORGANISMS
99
Microorganisms possess body parts that prevents disinfectant entry like an outer membrane that acts as a barrier to the uptake of disinfectants
INNATE RESISTANCE TO DISINFECTANT

BIOFILM
104
Uneven, cracked, or pitted surfaces can hide microorganisms and are difficult to disinfect.
SURFACE TOPOGRAPHY
105
the more concentrated the disinfectant, the greater its efficacy and the shorter the time necessary to achieve microbial kill.
