Flashcards in Test 3 Deck (50):
1

adenovirus

nonenveloped, DNA double stranded genome, linear dsDNA
cells clump and nuclear inclusions form, transformation of cells as a result of viral infections

2

poxovirus

eveloped, double stranded DNA

3

herpesviruses

enveloped, double stranded DNA genome
papovaviruses

4

papovaviruses

circular dsDNA, double stranded genome, noneveloped

5

parvoviruses

single-stranded genome, DNA nonevleoped

6

paramyxoviruses

single-stranded genome, nonsegmented, enveloped RNA virus

7

coronavirus

enveloped RNA virus, single-stranded genome nonsegmented

8

retrovirus

enveloped RNA, single-stranded genome encodes reverse transcriptase

9

influenza

ss RNA (-)

10

HIV

SS RNA (+) becomes DNA in the cell

11

enzymes in nucleocapsid

polymerase
reverse transcriptase

12

enzymes in envelopes

hemagglutinin
neuraminidase

13

proliferation of cells

papillomavirus

14

fusion of host cells

respiratory syncta

15

no change in viral infection

rubella

16

bacteriophages

entry of nucleic acid causes cessation of host cell DNA replication, host cell lyses = lytic cycle

17

lysogenic conversion

bacterium acquires a new trait from its temperate phage

18

mastigophora parasitic species

trypanosoma
giardia
trihomonas vaginalis

19

T. brucei/T. cruzi

brucei- causes sleeping sickness

cruzi- causes chagas disease

20

sarcodina human parasites

entamoeba- amoebic dysentary

21

ciliophora parasites

paramecium

22

apicomplexa (sporozoa) obligate parasites

plasmodium (causes malaria), toxoplasma

23

platyhelminths

flat worms

24

cestodes

tape worm

25

nematode

round worm

26

tremetode

fluke

27

antibiotics from bacteria

streptomyces, bacillus

28

antibiotics from molds

penicillium, cephalosporium

29

cell wall inhibitor

pennicillin, cephalosporin, neosporin, vancomycin

30

cell membrane inhibitors

polymixin, causes loss of selective permeability - used topically

31

DNA/RNA antimicrobial target

inhibit replication and transcription. inhibits gyrase (unwinding enzyme), quinolones, inhibits RNA polymerase, ciprofloxin

32

protein synthesis target of antimicrobial

50s- erythromyocin, clindamyocin
30s- streptomyocin, tetracycline

33

folic acid synthesis

blocks pathways and inhibits the metabolism- sulfonamides, trimethoprim

34

leukocidins

toxic to white blood cells, produced by streptococcus and staphylococcus

35

extracellular surface layer

makes it difficult for the phagocyte to engulf them

36

three ways to damage the host cell

exoenzymes, toxins, blocked phagocytic response

37

toxogenicity

power to produce toxins

38

progression of infection chart

Incubation
Prodromal
Invasion
Convalescent
Recovery

39

septicemia

blood infection

40

leukocytosis

increase in wbc

41

vector

live animal that transmits infectious agents from one host to another

42

fomite

inanimate object that transmits infectious agents, indirect

43

nosocomial infections

infectious diseases that are acquired or developed during a hospital stay

44

etiologic agent

causative agent in a disease

45

infectious dose- morbiditiy

number of microbial cells required to cause infection in 50% of subjects, ID50

46

lethal dose- mortality

number of cells required to cause death in 50% of the subjects

47

antisepsis

destroys most microbial life reducing contamination on living surfaces

48

decontamination

the mechanical removal of microbes from the animate or inanimate

49

dessication

dehydration of vegetative cells when directly exposed to normal room air

50

lyophilization

combining state of freezing and drying used to preserve microorganisms and other cells in a viable state for many years
