Week 1

Question 1

The study of parasitic relationships that affect domestic, wild,exotic, lab animals to an extent parasites that have potential to be transmitted from animals to humans

Answer 1

Veterinary parasitology

Question 2

Any association (temp/permanent) between 2 organisms of diff specie

Sym= together, Bios= living together.s.

Answer 2

Symbiosis

Question 3

One symbiont benefits from association, the other is neither helped nor harmed.

(ex. Barnacles on whales; egret eating insects stirred up by grazing animal; bird uses a tree hole for housing.)

Answer 3

Commensalism

Question 4

Both symbionts benefit from association.

(Ex. Bacteria/ protazoans that live in the stomach of deer, cows, horeses, rabbits aid in digestion and the animal provides the organism w/ an environment to live)

Answer 4

Mutualism

Question 5

Small organisms is mechanically transported by the large symbionts.

(Ex.flies transport bacteria from one animal to another

Answer 5

Phoresis

Question 6

A short term relationship in which one symbiont benefits at the expense of the other.

Answer 6

Predatory/ prey

Question 7

(Ex. Fleas, ticks, ear mites)

Answer 23

Obligatory parasite

Question 24

Answer 24

Facultative parasite

Question 25

Parasite that is found in a host which it usually doesn’t live.

(ex. Heartworms in humans)

Answer 25

Incidental parasite

Answer 27

Permanent parasite

Question 28

Gets on host to feeds then returns to environment.

Ex. Ticks, mosquitoes

Answer 28

Temporary parasite

Question 29

Parasites that infect only one species are considered host specific (ex. Equine parasitic) parasites that can infect more than one species have host specificity. (ex. fleas that feed on anything)

Answer 29

Host specificity

Question 32

Harbors parasites in the adult matured reproductive stage. (Ex canine heartworms)

Answer 32

Definitive host

Question 33

Answer 33

Intermediate host
