INCIDENTAL

20
Q

those found within the host from early life to maturity

A

PERMANENT

21
Q

type of parasite wherein the larval stage develops in a host while the adult is free living

A

INFECTIVE STAGE

27
Q

forms that can be detected via laboratory retrieval methods.

A

DIAGNOSTIC STAGE

28
Q

Usually an individual harboring the parasite but do not show any signs and symptoms; a state wherein the parasite lives in or on the tissues of its host without causing evident harm

A

CARRIER

29
Q

there is a sudden rise in the
incidence or an outbreak of
considerable intensity occurs in a disease in human population

A

EPIDEMIC

30
Q

there is a steady, moderate level of disease in human population

3 DISTINCT DISCIPLINES

A

CLASSIFICATION, NOMENCLATURE, AND IDENTIFICATION

33
Q

Organization of microorganism that share similar morphologic, physiologic, and genetic traits into
specific groups or taxa.

A

CLASSIFICATION

34
Q

naming of organism according to established rules and guidelines for universal recognition, with a binomial system (genus and species)

A

NOMENCLATURE

35
Q

process by which a microorganism’s key features are delineated, which can be compared with other characterized microorganisms.

A

IDENTIFICATION

36
Q

simple organisms, unicellular, others are aggregation of similar cell with little or no differentiation in complex structure or function.

A

ALGAE

37
Q

very small non-cellular parasite or pathogens of plants,
animals and bacteria, even protist.

A

VIRUSES

38
Q

minute, unicellular procaryotic orgnanism, multiply by
binary fission, plant-like, microscopic organism which lacks chlorophyll.

A

BACTERIA

39
Q

unicellular eukaryotic organism, differentiated on the
basis of morphology, physiology and nutrition.

A

PROTOZOA

40
Q

eukaryotic lower plants devoid of chlorophyll, usually
multicellular but not differentiated into roots. stems, and leaves, unicellular single-celled (yeast), composed of mycelium (filaments and masses of cells which make up the body, reproduce asexually and or sexually.

A

FUNGI

41
Q

readily observable characteristics
(visually present)

A

PHENOTYPIC

42
Q

genetic makeup of the organisms (genes and nucleic acid manipulation)

A

GENOTYPIC

43
Q

involves only one intermediate host.

A

MONOXENOUS

44
Q

involves more than one intermediate host.

A

HETEROXENOUS

45
Q

refers to the development of a parasite in its earliest form and its survival and development in the outside environment and within the host.
