1

Infection

invasion of a susceptible host by a potentially harmful microorganism (pathogen) resulting in disease

2

Colonization

presence & growth of microorganisms within a host but without tissue invasion or damage

3

Fungi

a principle infecting agent includes yeast, molds & mushrooms grow in single cells or in multicellular filmentous colonies

4

Virulence

microorganisms ability to produce disease

5

Resevoir

a place where microorganisms survive, multiply, & wait to transfer to a susceptible host

6

Carrier

human who shows no signs of disease but carry & can transmit microorganisms

7

Immunity

state in which a host in not susceptible either artificially or naturally

8

Active Immunity

results from having a disease & mounting an immune response that usually lasts a lifetime

9

Passive Immunity

acquisition of an antibody by one person from another, usually lasts short duration (weeks-month) EX: mother to baby

10

Antibodies

immunoglobulins, essential to the immune system, produced by lymphoid tissue in response to bacteria, viruses or other antigens

11

Pathogenecity

ability of pathogenic agent to produce disease

12

Normal Flora

large amounts of microorganisms residing on surface & deep layers of skin, in saliva, oral mucosa & intestinal walls

13

Inflammation

cellular response of the body to injury or infection

14

Necrotic

of or pertaining to the death of tissue in response to disease or injury

15

Antigen

foreign material entering the body that creates a series of responses that changes the biological make-up of the body

16

Health-Care Acquired Infection (HAI)

when a patient develops an infections that was not present or incubating at the time of admission to a healthcare setting

17

Exogenous Infection

comes from microorganisms found outside the individual

18

Endogenous Infection

occurs when part of a patient flora becomes altered & overgrowth occurs

19

Aseptic Technique

an effort to keep patients as free from exposure to infections-causing pathogens as possible

20

Medical Asepsis

"clean techniques" including procedures used to reduce the # & prevent the spread of microorganisms

21

Surgical Asepsis

"sterile techniques" including procedures to eliminate all microorganisms

22

Sterilization

destroys all microorganisms & their spores

23

Standard Precautions

used routinely with every patient regardless of diagnosis, including hand hygiene & use of barriers (gloves)

24

Transmission-Based Precautions

required when patient has communicable disease or infection that is easily transmissible

25

Airborne Precautions

safeguards to reduce the risk of transmission of infection through air a person breathes

26

Contact Precautions

safeguards to reduce the risk of transmission of infection by direct or indirect contact

27

Droplet Precautions

safeguards to reduce the risk of droplet transmission of infectious agents

28

Aerobe

a microbe that is able to live and reproduce in the presence of oxygen

29

Anaerobe

a microorganism that can live and reproduce in the absence of oxygen

30

Airborne Transmission

transmission of infection through the air a person breathes
