micro ch 12
問題一覧
1
to interfere with the growth of microbes within a host
2
Gram-positive rods, actinomycetes, and fungi
3
the nature of the infecting microbe, microbes current sensitivity to available drugs/antibiotics, the overall medical status of the infected host (immuno-compromised or healthy)
4
Kirby-Bauer test and E-test diffusion test
5
microbes susceptibility/resistance to a drug
6
mueller Hinton
7
cover the entire plate with microbe then evenly distribute drugs throughout visual zone of inhibition
8
disks being same size and media used (controls the diffusion)
9
strips contain different concentrations of a drug and for results look where on the strip the zone stops to find zone of inhibition
10
ratio of the dose that is toxic to humans and is close to MIC
11
high
12
toxic dose/ MIC
13
lowest dose that is most effective
14
destroys the infective agent without harming the hosts cells
15
target a specific cell component that is found only in certain microbes
16
mycolic acid
17
targets cell components common to most pathogens
18
ribosomes
19
broad spectrum
20
narrow
21
spontaneous mutations in critical chromosomal genes and acquisition of new genes or sets of genes via horizontal transfer
22
conjugation, transformation, and transduction
23
bacteria sex, uses sex polis to attach and share genes
24
transfer of free floating DNA into cell
25
transfer by virus, virus takes bacteria and transfers it to new cell
26
new enzymes are synthesized inactivating the drug, uptake of the drug into a bacterium is decreased, and drug is immediately eliminated
27
use outdated or weakened antibiotics, use antibiotics for common cold or other inappropriate conditions, does not finish the antibiotic days, uses someone’s else’s left over prescription
28
probiotic yogurt
29
fractals encourage the growth of Bifidobacterium in the large intestine and discourage the growth of pathogens
30
replace microbes lost during antimicrobial therapy
31
nutrients that encourage the growth of beneficial microbes
