Flashcards in Test 2 Deck (38):
1

the invasion of the body by macroscopic parasites, those unable to be seen with the unaided eye.
ex; maggots

infestation

2

ability of microorganism to produce disease. Attenuation implies a weakening or reduction in the virulence of a MO.

virulence

3

diseases caused by infectious agents that can be transmitted between or are shared by animals and humans

ex; encephalitis or malaria

zoonotic

4

a hospital acquired infection, one obtained while in the hospital

nosocomial

5

literally, pus in the blood; a form of septicemia cause by cryogenic (pus forming) bacteria

pyemia

6

an infection which causes a fever (elevated temp)

pyRemia

7

a sudden, sever and overwhelming infection, such as spinal meningitis

fulminating

8

infection throughout the body, having been spread by the bloodstream or lymphatic system

generalized

9

a seemingly inactive infection; it is apparently held in check by the body's defense but may spread when the body resistance is reduced.

ex: cold sores or syphilis

latent

10

an infection in which the clinical symptoms are not recognized or immediately detectable.

ex; TB

inapparent

11

an infection in which all the symptoms are easily recognized

ex: rubella

typical mumps

12

an infection in which all the symptoms are not easily recognizable, meaning that it could be confused with another infection

atypical

13

any MO that causes disease in man. A non-pathogen does not cause disease in man.

pathogens

14

types of pathogens

normal flora
opportunists
strict (obligate) pathogens

15

MO's that live and grow in/on the human body. Most are non-pathogens.

normal flora

16

MO's that produce infection only under especially favorable conditions, that is, they await the right opportunity to cause infection. Pathogens contained in a person's normal flora are usually opportunists since they alone cannot penetrate unbroken skin.

opportunists

17

MO's that will cause an infection in man every time that a person is exposed to them. They are never a part of one's normal flora.

strict (obligate) pathogens

18

presence of infectious material, without a reaction necessarily being produced. This term can also refer to inanimate objects.

ex: fomite

contamination

19

an infection which occurs during the course of a chronic disease and causes death.

terminal

20

the presence of toxins (poisonous substances) in the blood.

toxemia

21

invasion of the bloodstream by pathogenic organisms with their subsequent multiplication therein. Common name is "blood poisoning"

ex: sepsis

septicemia

22

an infection in which the causative agent comes from outside the body.

exogenous

23

an infection which is caused by microorganisms which are normally present within the body.

endogenous

24

an infection of sudden onset and short duration

acute

25

an infection of slow onset and long duration

chronic

26

an infection capable of being transmitted, either directly or indirectly, from host to host. Contagious means highly communicable

communicable

27

an infection that is constantly present to a greater or lesser degree in a community.

ex: cold flu

endemic

28

and infection which attacks a large number of people in a community in a short period of time.

epidemic

29

worldwide epidemic; an infection which becomes an epidemic in a number of countries at the same time.

ex: flu in 1919 killed 20 million

pandemic

30

an infection which occurs only occasionally (now and then) in a community

sporadic

31

initial (first) infection of a mixed infection

primary

32

an infection due to two or more organisms.

ex: 2 or more infections occurring at the same time

mixed

33

the second and generally more complicating infection in a mixed infection

secondary

34

an infection in which the pathogenic organisms remain confined to a particular area.

ex: abscessed tooth

local

35

an infection confined to a particular area, but from which the bacteria spread to other parts of the body

focal

36

infection throughout, spread generally over the body by the bloodstream or lymphatic system.

ex: septicemia

general

37

a condition in which bacteria are in the bloodstream, but are NOT multiplying there.

bacteremia

38

GET DEFINITION

meningococcemia
