Question 7

-EMIA

Answer 7

Blood

Question 8

HEALTH

Answer 8

The state of well being of an animal in which all body parts are functioning normally.

Question 9

HOST- PARASITE RELATIONSHIP

Answer 9

A relationship between the host and the living agent

Question 10

INCUBATION PERIOD

Answer 10

The period when the infectious agent gets established within the host’s body and rapid multiplication of the organism.
the host remains visibly healthy

duration varies on the microorganism

Question 11

INFECTIOUS

Answer 11

That a disease is caused by a living agent

(doesn’t indicate if it is infectious at all)

e.g. parasites, fungi, bacteria, viruses

Question 12

INFECTIOUS DISEASE

Answer 12

A disease caused by a living agent (e.g bacteria, fungi, viruses, external parasites, internal parasites)
often contagious

Question 13

LOCAL INFECTION

Answer 13

Infectious agents which have a predilection for a particular location in the body, or have invaded an area and remain active in that area

Question 14

MORBID

Answer 14

sick

Question 15

NON-INFECTIOUS DISEASE

Answer 15

A disease in which there is no living agent involved (eg. Hit by a car, skin tumor)

Question 16

PERACUTE DISEASE

Answer 16

The onset of the disease is very acute, with a duration of a few hours

Question 17

PARASITE

Answer 17

Organisms that live off and challenge living host tissues

Question 18

PARASITISM

Answer 18

A challenging relationship between microorganism and host. The host may be harmed.

Question 19

PERIOD OF CONVALESNCE

Answer 19

This is the period where the animal’s immune system overcomes the infectious agent and the animal’s health improves. The infectious agent may still be present.
This period is not always reached.

Question 20

PERIOD OF ILLNESS

Answer 20

the development of clinical signs. Visibly sick. If the animal dies they will not progress past this stage.

Question 21

SAPROPHYTES

Answer 21

Bacteria that live on dead material

eg in vet med:
infection due to the retained placenta of a calf
saprophytes create toxins in the uterus

Question 22

SEPTICEMIA

Answer 22

There is bacteria in the blood and the bacteria is multiplying there causing disease

Question 23

SUBACUTE DISEASE

Answer 23

Between acute and chronic, often of a weeks duration

Question 24

SYSTEMIC INFECTION

Answer 24

The infectious agent has gained access to the blood stream and has spread throughout the body.

Question 25

SYMBIOSIS

Answer 25

A beneficial relationship between microorganisms and host ex: the bacteria in the intestines

Question 26

TOXEMIA

Answer 26

The presence of toxins (poisons) in the blood (is a general term) (the toxin can come from many sources)

Question 27

IMMUNOBIOLOGY

Answer 27

The study of the response of the animal to organisms that cause disease Includes elements of: microbiology, pathology, and immunobiology

Question 28
