asepsis Flashcards
o Collective vegetation in an area
Resident flora
o Growth of microorganisms in body tissue where
they are not usually found
- Infection
If the microorganism produces no clinical evidence
of disease, the infection is called
asymptomatic or
subclinical.
Detectable alteration in normal tissue function
Disease
Ability of a microorganism to produce disease
Virulence
Transferable to individual by direct or indirect contact
Communicable disease
Ability to produce disease
Pathogenicity
o Freedom from disease-causing organisms
Asepsis
- All practices intended to confine a specific
microorganism to a specific area - Limits number, growth, and transmission of
microorganisms - Objects referred to as clean or dirty (soiled,
contaminated)
Medical asepsis
- Practices that keep area or object free of all
microorganisms - Practices that destroy all microorganisms and
spores - Used for all procedures involving sterile areas
of the body
Surgical asepsis (sterile technique)
