Q

What is an obligatory parasite?

A

A parasite that must live inside the host in order to survive.

20
Q

What is a psuedoparasite?

A

An object or creature that can be mistaken for a parasite, but is not an actual parasite.

21
Q

What is an indirect life cycle?

A

The parasite must go through a host in order to develop.

22
Q

Explain somatic migration.

A

Larvae travels from the stomach, through the hepatic portal circulation, then throught the liver and then proceeds to travel to different sites.

23
Q

Parasitism relationship

A

Involves two different species of organisms in which one lives on/in the other and may potentially cause harm.

24
Q

What is a parasite?

A

A small organism that lives on/ina larger organism that is the host.

25
Q

What are the majorclasses of parasites?

A

Multiple parasitism

Superparasitism

26
Q

What is a zoonotic disease?

A

A disease that can be transmitted between human and animal

27
Q

What is a direct life cycle?

A

A parasite is able to continue its life cycle in the same host

28
Q

What is a phoresis relationship?

A

Using another member to hitch a ride

29
Q

What is an intermediate host?

A

A host that harbors larvae, or immature stages of the parasite.

30
Q

What is tracheal migration?

A

Similar to somatic migration, but continues up the trachea and then into the esophagus only to end up where they started/

31
Q

What is an example of a protozoa?

A

Giardia

32
Q

Does a tapeworm require an intermediate host?

What is it?

A

Yes

Flea

33
Q

What isa periodic parastie?

A

A parastie that must make short frequent visits to a hostfor nourishment.

34
Q

Which period is longer, prepatent or incubation?

A

Incubation

35
Q

What is symbiosis

A

Living together

36
Q

The host’s expense may be…

A

Trivial, substantial or even unbearable

37
Q

What are the physical features of a tapeworm?

A

They are flat and segmented and have suckers on their heads

38
Q

What is an incubation period?

A

The time it takes a parasite to infect a host to the time it takes for the signs or symptoms to occur

39
Q

What is a prepatent period?

A

The time it takes a parasite to enter the host to how long it takes to be detected.

40
Q

What is a mutualism relationship?

A

Both organisms benefit

41
Q

Another word for helminths

A

Worm

42
Q

What are the physical features of a nematode?

A

They are round in cross-section, longer than they are wide and unsegmented

Q

What is an example of a helminth?

A

Roundworm

44
Q

What are some examples of arthropods?

A

Insects

Arachnids

45
Q

What is the difference between infection and infestation?

A

Infection-Caused by a parasite within the body

Infestation- Outside/ on the body or environment

46
Q

What are the two classifications of parasitism?

A

Multiple parasitisms

Superparasitism

47
Q

What is a commensalism relationship?

A

One benefits, the other doesn’t and the other is not harmed.
