Microorganisms are multiplying in or on a host

Infection or colonization

1

Microorganisms normally living in or on body

Microflora

2

What cause disease?

Pathogens

3

Pathogen capable of producing infection when host is weakened

Oppurtunistic pathogen

4

Small modified infectious host proteins

Prions

5

Manner of replication of prions

Not clearly known or understood

6

Where do bacteria like to grow?

Warm moist places

7

What stage is active replication without recognizable symptoms in host?

Incubation

8

Stage with initial appearance of symptoms most commonly malaise

Prodromal

9

When are you most highly infectious?

Prodromal stage

10

What stage is the maximum impact of infectious process with rapid proliferation and dissemination of pathogen

Acute

11

Stage where there is containment if the infection, elimination of pathogen, repair of danger tissue, and resolution of symptoms

Convalescent

12

What stage is total elimination of pathogen and no S/S of disease?

Resolution

13

When are you not infectious anymore?

Resolution stage

14

-itis

Inflammation

15

-emia

In the blood

16

Bacterial toxins in the blood

Sepsis or septicemia

17

Make an infection more likely to cause disease

Virulence factor

18

Exotoxins

Outside

19

Endotoxins

Inside

20

Help infective organism stick to body

Adhesion factor

21

Help keep immune system from killing infective agent

Evasive factor

22

After exposure to an infectious agent the body produces antibodies

Serology

23

Antibody that rises during the acute phase then falls

IgM

24

Antibody that remains elevated after the acute phase

IgG

25

What is the genetic material of viruses?

DNA or RNA but not both

26

What do viruses need to replicate and why?

Host cell because they have no metabolic capability

27

What happens when a host cell is "transformed"?

It carries the virus

28

What is a virus responsive to that makes it become active?

Stress or hormonal changes

29

What are the effects of viruses?

Protein synthesis stops, enzymes kills cells, host cells fuse, secondary bacterial infections
