Flashcards in Microbiology Chapter 13 Deck (32):
1

Proteins or glycoproteins found on attachment pili and capsules

Adhesins

2

White blood cells that engulf and destroy pathogens

Phagocytes

3

Enzyme that digest the protective coating on mucous membranes

Mucinase

4

Enzyme that digest the principal component of skin and hair, secreted by fungi

Keratinase

5

Enzyme that digest the principal fiber of connective tissue and is an invasive factor

Collagenase

6

Enzyme that digests hyaluronic acid

Hyaluronidase

7

Enzyme that increases blood clotting

Coagulase

8

Enzyme that dissolves blood clots

Streptokinase

9

Soluble proteins secreted by the pathogen.

Exotoxins

10

Part of the cell wall released into the host tissue

Endotoxins

11

Organisms that live on or in the body but do not cause disease

Normal (resident) biota (normal flora)

12

The capacity to cause disease. It depends on its ability to invade, multiply on or in a host and avoid the host's defenses.

Pathogenicity

13

The intensity of disease produced by a pathogen

Virulence

14

Resident or transient microflora that cause disease under certain conditions

Opportunists

15

Time between infection and appearance of signs and symptoms.

Incubation Period

16

Short period during which mild, nonspecific symptoms appear

Prodromal Phase

17

Period during which the individual experiences typical signs and symptoms of a disease

Invasive Phase

18

Period of healing

Convalescence period

19

Infection of a previously healthy person - Usually acute

Primary infection

20

Infection that immediately follows a primary infection. (Ear infection following a cold)

Secondary infection

21

Characteristics of a disease that can be observed by examining the patient (Swelling, redness, coughing, etc)

Signs

22

Characteristics of a disease that can be felt or observed by the patient. (Pain, nausea, headache, etc)

Symptoms

23

Combination of signs and symptoms that are indicative of a particular disease.

Syndrome

24

Individuals who harbor an infectious agent without having any observable symptoms

Carriers

25

An animal that transmits infectious organism from one host to another

Vector

26

Infection acquired in a hospital or other medical facility

Nosocomal infection

27

Set of guidelines established by the CDC (Center for disease Control) to reduce the risks of nosocomial infections. Also important for the prevention of transmission of AIDS.

Universal Precautions

28

Number of individuals affected by a disease during a set period of time in relation to the total number in the population.

Morbidity Rate

29

Number of deaths due to a disease in a population during a specific period in relation to the total population.

Mortality Rate

30

Infectious disease that exhibits a relatively steady frequency over a long time period in a particular georgraphic locale.

Endemic

31

Diseased increasing beyond what is expected for that population

Epidemic

32

The spread of an epidemic across continents

Pandemic
