parasitology terminology

Question 1

symbiosis

Answer 1

any association (temporary/permanent) between @least 2 living organisms of different species

Question 2

predatory-prey

Answer 2

• Symbiotic Relationship

- Short-lived, 1 member benefits @ others expense (wolves and deer)

Question 3

Phoresis

Answer 3

-Symbiotic Relationship
-smaller member carried by larger
(agent for cattle-pinkeye carried on sticky membrane on fly’s foot)

Question 4

mutualism

Answer 4

-Symbiotic Relationship
-both members benefit
(rumen in cows intestine are sheltered, cow can digest certain foods for nutrition)

Question 5

commensalism

Answer 5

-Symbiotic Relationship
-one benefits and the other neither benefits nor is harmed
(the remora fish and the shark )

Question 6

parasitism

Answer 6

• Symbiotic Relationship

- one lives in or on host and benefits from host but may cause harm to the host.

Question 7

parasitiasis

Answer 7

type of parasite that is present and could cause harm but host doesn’t exhibit signs related to the parasite

Question 8

parasitosis

Answer 8

type of parasite that is present and the host does exhibit symptoms related to the parasite

Question 9

ectoparasites

Answer 9

parasites that live outside the host (they INFEST)

Question 10

endoparasites

Answer 10

parasites that live inside the host (they INFECT)

Question 11

parasiticides

Answer 11

compound meant to kill parasites (both endo-/ecto-)

Question 12

Anthelmintics

Answer 12

kills worm shaped internal parasites

Question 13

Acaricides

Answer 13

kills mites and ticks

Question 14

Insecticides

Answer 14

kills insects

Question 15

Antiprotozoals

Answer 15

kills protozoans

Question 16

Aberrant Migration

Answer 16

when a parasite migrates or wanders into an inappropriate location or place it normally does live

Question 17

incidental parasite

Answer 17

a parasite that takes up residence in a host it normally does not live. (usually end of the road for that parasite)

Question 18

Facultative parasite

Answer 18

organisms that can be free living and do not require host to progress through life-cycle, but can become parasitic in a host

Question 19

Obligatory parasite

Answer 19

“obligate parasite”

organism that must live a parasitic life in order to survive or reproduce

Question 20

periodic parasite

Answer 20

organism that takes periodic trips to a host for sustenance and nourishment (mosquito or tick)

Question 21

Pseudoparasite

Answer 21

living things or objects that are seen under microscope that can me mistaken for a parasite (pollen, soil nematodes etc.)

Question 22

life cycles

Answer 22

development of a parasite throughout its life stages, might involve more than one host

Question 23

definitive host

Answer 23

host that house the adult (sexually mature) parasite

Question 24

intermediate host

Answer 24

specific host that houses a parasite but not to its adult stage. Parasite must find a way into the definitive host to progress further into life cycle

Question 25

paratenic host

Answer 25

intermediate host that houses, this parasite with encyst itself into the tissue and become dormant until it enters a definitive host.
“transport host”

Question 26

encysted parasites

Answer 26

encased in a cyst

Question 27

reservoir host

Answer 27

host in which the parasite occurs in nature and serves as a source of infection for humans and other animals
- capable of development into adult stages

Question 28

zoonosis

Answer 28

a parasite or disease capable of being transmitted to humans from an animal

Question 29

Naming of parasites we study

Answer 29

Genus and Species

Answer 32

egg laying with a larva in the egg

Question 33

larviparous
