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

Veterinary parasitology

2

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

Sym= together, Bios= living together.s.

Symbiosis

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.)

Commensalism

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)

Mutualism

5

Small organisms is mechanically transported by the large symbionts.

(Ex.flies transport bacteria from one animal to another

Phoresis

6

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

Predatory/ prey

7

One symbiont the parasite ,lives in or on the other, the host. The parasite is metabolically dependent on the host for survival.

Parasitism

8

Parasite is present on/ in hosts but there ARE NO clinical signs of the infection

Parasitasis

9

Parasite is present on/in hosts and THERE ARE clinical signs of infection.

Parasitosis

10

Used to treat ecto-/endo- parasites.

Parasiticides

11

Chemical compund that Kills roundworms, tapeworms, flukes, thorney headed worms.

Anthelmintics

12

Chemical comounds that kill mites & ticks.

Acaricides

13

Chemical compounds that kill insects

Insecticides

14

Chemical compunds that kills protozoans

Antiprotozoals

15

The study of parasites and deseases cause by parasites.

Parasitology

16

Smaller organisms that lives in/on a larger organism at the expense of the larger organism

Parasite

17

Parasite that lives IN the body of the host.

Endoparasite

18

Parasite that lives ON the body of the host.

Ectoparasite

19

Parasites restricted to one host species.

Homoxenous or monoxenous

20

Parasite have a very narrow range of desirable hosts.

Stenoxenous

21

Parasites have a very broad range of desirable hosts.

Euryxenous

22

Any diseases/parasite that is transmissable from animal to humans.

Zoonosis

23

Parasite that must lead a parasitic existence; most parasites of domestic animals are __________ parasites

(Ex. Fleas, ticks, ear mites)

Obligatory parasite

24

Organism that is usually free living(non-parasitic) in nature and developes a parasitic existence in certain hosts.(do not rely on a host for survival)

Facultative parasite

25

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

(ex. Heartworms in humans)

Incidental parasite

26

Parasite that has wondered from its usual site of infection into an organ or location in which it DOES NOT ordinarily live, also called erratic parasite.

(Heartworm larva in the brain of a cat)

Abberant parasite

27

Remains on the host through entire life cycle.

(Ex demodectic mites, ear mites, lice.)

Permanent parasite

28

Gets on host to feeds then returns to environment.

(Ex. Ticks, mosquitoes)

Temporary parasite

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)

Host specificity

30

Parasite that can infect both humans and animals.

Zoonotic
