Microbiology Test 1

Front 1

2 major problems with the standard definition of microbiology

Back 1

1. organisms refer only to living cells. In addition to the study of microorganisms, we also study infectious agents such as viruses, prions and viroids that are not considered to be living. We refer to these non-living agents as particles.
2. the naked or unaided eye can visualize objects as small as 0.1 mm

Front 2

standard definition of microbiology

Back 2

study of organisms too small to be seen by the naked or unaided eye. includes the roles of microorganisms in causing disease, changes they make in the environment and products that they generate

Front 3

what are the 5 kingdoms of the living world?

Back 3

1. protozoa
2. algae
3. fungi
4. bacteria and cyanobacteria

Front 4

what is Rickettsia?

Back 4

organisms that have leaky membranes and must exist inside of host cells

Front 5

what is binomial nomenclature?

Back 5

the naming of a species we use in two words

Front 6

the first word of a species, capitalized

Back 6

Genus

Front 7

the second word of a species, lower case

Back 7

species epithet

Front 8

true or false: the entire name is underlined or italicized

Back 8

true

Front 9

these organisms lack enzymes and therefore some of the metabolic machinery they need. this is the etiological agent of nongonococcal urethritis

Back 9

Chlamydia

Front 10

these organisms are not cells, not living, a type of PARTICLE-simplest version consists of nucleic acid surrounded by a protein coat

Back 10

viruses

Front 11

examples of obligate intracellular parasites

Back 11

Rickettsia and Chlamydia

Front 12

true or false: viruses use the Binomial Nomenclature to name themselves

Back 12

false. they are not living and are not organisms, therefore viruses cannot be named

Front 13

these organisms are not cells, not living, no nucleic acid, a type of particle. these are also obligate intracellular parasites. responsible for causing BSE, which causes Mad Cow disease

Back 13

prions
