A: Overview Flashcards
Sterilization
means there will be no viable cells or endospore
Disinfection
vegetative pathogens will be killed. endospores will not be killed
What do bacterial agents do
kill bacteria
What do bacteriolyticl agents do
lyses bacteria, killing them
What do bacteriostatic agents do
stop bacterial growth
The efficiency of antimicrobial agent affected by (4)
pop size, growth stages of cells, temp, environment
How does pop size affect antimicrobial agent
the larger the pop, the longer it takes
How does gowth stages of cells affect antimicrobial agent
cells in stationary phase and endospores harder to kill
How does temp affect antimicrobial agent
higher temp increases the activity of most chemicals
How does environment affect antimicrobial agent
organic matter protects bacteria from chemicals eg in biofilms, vomit, blood and feces.
