ubiquitous

A

2
Q

BACTERIA

A
  1. ubiquitous

2. most bacteria are not pathogenic in their natural habit, only 1 in 50,000 bacteria causes disease

3
Q

opportunistic pathogen

A

infection caused only once pathogen is given the proper circumstance/situation

4
Q

normal biota

A

harmless and some are even beneficial, naturally live on skin, gut, saliva, etc. – are NOT easily removed from skin

5
Q

transient organisms

A

found on the skin for short periods of time, but do not grow there – acquired from contact with contaminated surafaces and are usually easily removed – can cause disease – easily transferred person to person

6
Q

Hand Washing

A

best practices that can limit the transmission of pathogens from one human to another – 3 components: soap or detergent, friction and antimicrobial agent

7
Q

Saponification

A

soaps are produced by this process – involves treating a fat with alkali (base) in the present of heat. Soaps and detergents emulsify the skin oils in which bacteria is trapped

8
Q

Surfactants

A

are amphipathic, which means they have a lipid-soluble portion and water-soluble portion

9
Q

Friction

A

helps us physically remove the emulsified skin oil with the trapped bacteria

10
Q

Antiseptic

A

antimicrobial agent – helps us remove remaining bacteria without damaging the skin

11
Q

amphipathic

A

has a lipid-soluble portion and water-soluble portion
