A

in a parasitic relationship, the member that lives on or within the host.

33
Q

Parasitism means?

A

type of symbiotic relationship between two organisms of different species in which one member (the parasite) lives on or within the other member (the hosts and may cause harm; parasite is metabolically dependent on host for its survival

34
Q

Parasitology means?

A

the study of parasitic relationships (such as host-parasite relationships)

35
Q

A

a host used for transport of a parasite. The parasite does not go through any developmental stages.

A

type of symbiotic relationship in which the smaller member in the relationship is mechanically carried by the larger member

38
Q

Planta means?

A

One of the 5 kingdoms in the classification scheme (Planta, aminalia, protista, monera, and fungi)

39
Q

Predator means?

A

an animal that kills another animal and eats it. example - lion

40
Q

Predator-prey relationship means?

A

extremely short-term symbiotic relationship in which one symbiotic benefits at the expense of the other; for example, a lion (the predator) will kill a zebra (the prey). The prey ultimately pays with its life and serves as a food source for the predator.

41
Q

Prey means?

A

what the predator eats

42
Q

Protista means?

A

One of the 5 kingdoms in the classification scheme (Planta, aminalia, protista, monera, and fungi) - means eukaryotic - one-celled living organisms

43
Q

Pseudoparasite means?

A

living creatures or inani-mate objects that are not parasitic but may be mistaken for, or erroneously identified as, parasites

44
Q

Reservoir hosts means?

A

vertebrate host in which a parasite or disease occurs in nature and is a source of infection for humans or other domesticated animals.

45
Q

scientific name means?

A

name for a living organism that is composed of two Latin words, usually written in italics.

46
Q

specific epithet means?

A

the type of animal in a genus

47
Q

stenoxenous parasite means?

A

parasite with a narrow host range

48
Q

symbiont means?

A

each living organism in a symbiotic association

49
Q

symbiosis means?

A

any association (temporary or permanent) between at least two living organisms of different species

50
Q

Transport host means?

A

special type of intermediate host in which the parasite does not undergo any development, but instead remains arrested, or encysted (in suspended animation) within the host’s tissues; also called paratenic host

51
Q

Veterinary parasitology means?

A

the study of parasitic relationships affecting domesticated, wild, exotic and laboratory animals

52
Q

Zoonosis means?

A

any disease or parasite that is transmissible from animals to humans

53
Q

What are the 5 types of symbiotic relationships?

A

predator-prey, phoresis, mutualism, commensalism,and parasitism

54
Q

Veterinary parasitology is concerned with only two of these kingdoms as true parasites of domesticated animals which are?

A

Animalia and Protista

55
Q

Animalia consists of?

A

platyhelminths (flatworms–treatodes (flukes) and cestodes (tapeworms), nematodes (roundworms), acanthocephalans (thorny-headed worms), annelids (leeches), and arthropods (insects, mites, ticks, spiders, pentastomes, and other creatures with jointed appendages)

56
Q

Protista consists of?

A

protozoans (unicellular organisms)

57
Q

Moraxella bovis is what?

A

bacterium and is the etiologic agent of infectious bovine keratoconjunctivitis or pinkeye of cattle

58
Q

Musca autumnalis is what?

A

face fly - the one that carries the infection called pinkeye to one cow to another with its sticky foot pads

59
Q

What is keratoconjunctivitis?

A

pinkeye

60
Q

What is parasitosis?

A

the parasite is present on or within the host and does produce obvious injury or harm to the host animal

61
Q

A parasite can cause ______ in some animals with a low parasite burden or number; however, it may also cause _____ with a high parasite burden.

A

parasitiasis

parasitosis

62
Q

Endoparasite will produce an ____ within that host.

A

infection

63
Q

D. immitis is the what?

A

the canine heartworm

64
Q

___ ____infects more than 300 species of warm-blooded vertebrates; its sexual stages only occur in the feline.

A

Toxoplasma gondii

65
Q

Genus name indicates?

A

the group to which a particular type of animal or plant belongs

66
Q

What does the specific epithet indicate?

A

the type of animal itself

67
Q

Compare and Contrast intermediate host vs. definitive host?

A

The intermediate host (such as a mosquito) is a host that harbors the larval, juvenile, immature, or asexual stages of the parasite, then transfers it to a definitive host (such as a dog who becomes the one that harbors the adult, sexual, or mature stages of the parasite - So both intermediate and definitive hosts helps the parasite survive and complete its life cycle but do this in different ways.

68
Q

Compare and Contrast parasitosis vs. parasitiasis?

A

Both parasitosis and parasitiasis live on or within the host, but with parasitiasis there is not outward signs that the parasite is in the animal. With parasitosis there is outward signs that the parasite is in the animal causing harm.

69
Q

Compare and contrast infestation and infections?

A

An infection is a condition caused inside the host’s body while an infestation is a condition being caused on the outside of the host’s body. Both cause a condition for the animal.

70
Q

Compare and contrast common name vs. scientific name?

A

Common and Scientific are both name of plants or animals. Common names are name given to a species and may be different in different parts of the world but with a scientific name - the species is given two name, the first name is capitalized and indicates the genus name (the group that the particular animal or plant belongs). The second name is not capitalized and is the specific epithet and indicates the type of animal itself.

71
Q

Compare and contrast anthelmintic vs. insecticide?

A

Both are compounds that either kill parasites or insects

72
Q

Compare and contrast obligatory parasite vs. facultative parasite?

A

Both can lead a parasitic existence, but only facultative parasite can also be free-living (nonparasitic)

73
Q

Compare and contrast stenoxenous parasite vs. euryxenous parasite?

A

Both are parasites but stenoxenous has a narrow host range where euryxenous has a broad host range
