Flashcards in Asepsis Deck (43):
1

Pathogen

Micro organism that causes disease

2

Induce infection to the patient through

Contact with the environment personnel or equipment

3

Bacteria

Free living important in health and disease. Aerobic or anaerobic. Shape rod or cocci Spirochete.
Can produce resistant spores

4

Viruses

Simplest microbe defined by RNA or DNA base. Enveloped or non-envelope. Obligate intracellular parasites, confined to a specific host entirely dependent on that host.

5

Fungi

Non-chlorophyl bearing plantlike organisms.
Can produce resistance spores.

6

Protozoa

Uni cellular organism

7

Nocosomial infections

Hospital acquired infections are caused by, viral, bacterial, and fungal pathogens

I.e.
blood stream infection
Respiratory infection
Gastrointestinal
Surgical site infection

8

Fomite

Any in animate object capable of carrying infectious organisms transferring them from one individual to another

9

Medical asepsis is:
Medial asepsis is referred to as:

- reduce number of pathogens
- referred to as clean technique

10

Medical asepsis used in administration of :

-Medications
-enemas
-tube feedings
-daily hygiene

11

What is #1 in medical asepsis

Hand washing

12

Surgical a sepsis is:
Referred to as:

Eliminates all pathogens
Referred to as sterile technique

13

Surgical asepsis used in:

-Dressing changes
-Catheterization
-Surgical procedures

14

Aseptic technique

Term used to describe all the precautions taken to prevent contamination and ultimately infection of a surgical incision

15

Aseptic technique its purpose

To minimize contamination so that post operative healing is not delayed

16

Contamination

Implies the presence of Micro organisms.
Contamination of a wound can but does not necessarily lead to infection

17

Infection

Micro organisms in the body or a wound multiply and cause harmful effects

18

Disease

Any process that detrimentally interferes with the function of an organism. Include abnormality of structure or function

19

Microbe

Also known as micro organism a living organism too small to be seen with the unaided eye

20

Normal flora

Microbes usually found in healthy animal’s

21

Resistance

Some of all factors contributing to the ability of an animal to overcome invasion by pathogen’s

22

Sepsis

Presence of pathogen’s or there by products in blood or tissue of patients

23

Asepsis

Complete absence of living pathogenic microbes. Not there spores.

24

Sterile

Complete absence of microbes and their spores

25

Non- sterile

Not sterile, may or may not be contaminated with microbes

26

Surgical asepsis

Body of techniques to maintain an object or area as free of all microbes as possible. Used whenever body tissues are penetrated.

27

Medical asepsis

Body of techniques used to reduces the number of microbes and the transmission of pathogens

28

Sanitation

Any cleansing measure intended to prevent dz and promote health; destroys about 98-99% of all microbes

29

Disinfection

Application of an agent that possess the property of destroying or inhibiting the growth of microbes on inanimate objects. Destroys about 99% of all microbes

30

Antiseptic

Inhibits or prevents growth of microbes on living tissues

31

Sterilization

Process to rid an object of 100% of all microbes and their spores

32

Cold sterilization

Immersion of an object into a disinfectant solution to reduce the level of contamination

33

Transmission

Passage of microorganisms from one host to another

34

Infectious

Ability of a microorganism to invade a host

35

Contagious

Describes the ease of which a microbe is able to invade a new host

36

How to prevent infection?

Limit FOMITES: clean, santize, disinfect and or sterilize to limit contagion on inanimate objects

37

How to prevent infection cont:
ISOLATION

Isolate infected animals in appropriate areas with no contact with healthy animals. This includes preventing spread of dz through appropriate ventilation, cages, etc.

38

How to prevent infection cont.
QUARANTINE

Placing newly acquired animals for several days to weeks in areas not exposed to healthy animals

39

How to prevent infection cont.
WASH

Wash hands, scrub, surgical prep

40

How to prevent infection cont. PREVENTION

Prevent the spread of microorganisms through vaccines and or use of snit-microbial, education.

41

How does the HOST prevent infection:

A. Immune sys - white blood cells sys ( t and b cells) lymphatic tissue and sys
B. Physical barriers - skin, hair
C. Mucus
D. Specialized cells-collocates cells in respiratory tissue, blood/brain Barrie’s
E. Elimination of wast- urination, vomiting, defeating, sweat
F. Fever
G. Individual cells- phagocytosis, micro enzymes, antigen, recognition, autolysis

42

How an ANTIGEN overcomes host?

A.release of toxins H1N1 in influenza, sepsis (pyometra)
B. Virulence ability to avoid hosts immunity and invade host
C. Spore formation resistance to extreme temps, detergents
D. Ability to hide from hosts immune system: capsule to prevent antigen recognition, hide in cells DNA or RNA
E. Ability to stick to host: use of pili
F. Ability to spread easily: ability to irritate and destroy tissues which can cause host to cough, sneeze, diarrhea, flagella
G. Ability to replicate: use of host ATP, DNA, RNA, to aid in replication

43

Autoclave

Steam under pressure to destroy all living microorganisms on inamorata objects and surfaces
