1

The study of defense against disease

Immunology

2

Infectious diseases are caused by?

Bacteria
Viruses
Parasites

3

The study of how microorganisms spread?

Epidemiology

4

Zoonotic diseases focus on?

food animal infections

5

Contains no symptoms?

Carrier

6

These "_______________" are everywhere!
-On you
-In you
-Next to you

Part of life and the whole ecosystem
(We cannot live without them)

Micro-organisms

7

Type of micro-org. that lives in hot water springs, antarctic cold, and the deep sea?

Extremophiles

8

No importance for animals and disease, still part of the ecosystem?

Free living bacteria

9

Micro organisms that NEED a host to survive

Obligate symbionts

10

Species that live together by choice.

Facultative symbionts

11

Cause no harm in "normal" conditons?

Non-pathogenic

12

Can cause disease if conditons are stressful but in normal environment it causes no harm (Skin flora)

Facultative pathogenic

13

An infection caused by an infectious agent that is already present in the body, but has previously been inapparent or dormant.

Endogenic infection

14

Disease can occur when microbes included in normal bacteria flora enter a sterile area of the body such as the brain or muscle.

Exogenic infection

15

are those bacteria that must cause disease in order to be transmitted from one host to another. These bacteria must also infect a host in order to survive, in contrast to other bacteria that are capable of survival outside of a host.

Obligate pathogenic

16

-pathogen does not want to kill its host before the pathogen can replicate and spread to new host
-evolve to reduce virulence

(generally don't need treatment)

Balanced pathogenicity

17

-normal conditions of the pathogen have changed in some way and establishes in an un-natural host (man instead of animal), pathogen does want to kill/harm its host while the pathogen can replicate. Causes high damage/death

Unbalanced pathogenicity

18

Invasion and multiplication of micro organism, eventually with disease (but does not always mean disease)

Infection

19

Causes structural and functional damage of the organism

Disease

20

disease that has no recognizable clinical findings, "Don't really feel well but not truly sick"

Subclinical disease

21

a disease that will most often make you sick given the "opportunity" of a damaged or weakened immune system. Need precondition before disease actually shows

Opportunistic Disease

22

is the presence of disease-causing bacteria in the blood

Septicaemiae disease

23

is the presence of bacteria in the blood.

Bacteraemia

24

brief and severe disease where it's too late when you actually can see issues with the animals, the farmer may walk out to see sick and dead animals (pneumonia)

Hyperacute

25

conditions are severe and sudden in onset. This could describe anything from a broken bone to an asthma attack. "the animal doesn't feel well one day, next day they REALLY DON'T feel well) Animal got sick all of a sudden

Acute

26

A vaguely defined state that is clearly not acute, but rather between acute and chronic. A long term condition that happens over time.

Subacute

27

disease lasting 3 months or more, by the definition of the U.S. National Center for Health Statistics. Generally cannot be prevented by vaccines or cured by medication, nor do they just disappear. "Hard to cure, hide in white blood cells"

Chronic

28

You cannot treat toxins with these?

Antibiotics

29

Minority of micro-organisms cause_______?

Disease

30

Esherichia coli is carried in the intestines of older pigs and in poultry. Staphylococcus aureus causes mastitis, skin infections, septicaemiae. What types of pathogens are these?

Facultative pathogen
