Module 3 Antibiotics Flashcards
(214 cards)
1
Q
Describe selective toxicity
A
It is the ability to enjoy target so organism without injuring other cells
Indicates ability of an antibiotic to kill or suppress microbial pathogens without causing injury to the host
2
Q
What is the difference between bacteria cell wall and mammalian cell walls?
A
Bacterial cell walls are rigid and thick. (If It were not for the cell wall bacteria would absorb water and Burst)
Mammalian cells have no cell wall so drugs don’t affect this
3
Q
Which drug class selectively inhibits an enzyme needed to make folic acid?
Why does in affect bacteria but not us?
A
Sulfonamides Inhibit an enzyme needed to make folic acid
Extra info: Bacteria my synthesize folic acid themselves they can’t take it from dietary sources like us
4
Q
What 2 drug classes inhibit bacteria cell wall synthesis?

5
Q
Which Drug class causes LETHAL inhibition of bacterial proteins synthesis?
A
Aminoglycosides (gentamicin)
6
Q
Which drug class causes NON-LETHAL inhibition of protein synthesis?
How do they differ from lethal inhibition?
A
Tetracyclines
They differ from aminoglycosides because they only slow microbial growth
7
Q
Which three drugs inhibit bacterial synthesis of DNA and RNA?
A

8
Q
What are anti-metabolites?
A
Drugs that disrupts specific bio chemical reactions
Trimethoprim and sulfonamides
9
Q
What is the difference between bactericidal drugs and bacteriostatic drugs?
A
Bacteriocidal drugs are lethal and kill bacteria directly
Bacteria static drugs slow bacterial growth but elimination of bacteria is needed to be done by the host
10
Q
What are four basic mechanisms for microbial drug-resistance?
A
They can decrease the concentration of a drug at its site of action
Alter the structure of drug target molecules
Produce a drug antagonist
Cause drug inactivation
11
Q
What is a super infection?
A
An infection that appears during the course of treatment for a primary infection
12
Q
What are three principal factors that must be considered when choosing or selecting an antibiotic?
A
Identify the infecting organism, drug sensitivity to the infecting orgasm, and host factors
13
Q
What is empiric therapy in regards to abx therapy?
A
Never send a patient home with an infection because you’re waiting on lab results.
Based on knowledge and assessment give a broad-spectrum agent as initial treatment and wait for culture and sensitivity results and if you need to contact the patient, you can switch to a more selective antibiotic for the organism
14
Q
drug levels should be how many times the minimal inhibitory concentration ?
A
4-8 times the MiC are often desirable
Antibiotics must be present at the site of infection, dosages should be adjusted to produce drug concentrations that are equal to or greater than the minimal inhibitory concentration
15
Q
Antibiotic dosage too high can increase the risk for what?
A
Superinfection
16
