Questions with Verified
Answers
The mode of action of neomycin, an aminoglycoside antibiotic, is
Inhibiting the function of the small ribosomal subunit
Inhibiting the function of the large ribosomal subunit
Inhibiting DNA replication
Inhibiting cell wall synthesis
Inhibiting folic acid biosynthesis - -Inhibiting the function of the small
ribosomal subunit
- Toxoplasmosis is a disease that may be transmitted in tissues transplanted
from an infected donor to a susceptible recipient. What kind of disease
transmission is described by this scenario?
Indirect, water, vehicle transmission
Indirect, biologic, vehicle transmission
Direct contact transmission
Indirect, fomite, vehicle transmission
Mechanical vector transmission - -Indirect, biologic, vehicle transmission
- A used Kleenex tissue or doorknob harboring infectious agents is
considered a
Vector
Carrier
Host
Fomite
Reservoir - -Fomite
- This infection spreads very easily. Most often it is spread by hand, after the
hand has been in contact with the infected area. One person with pink-eye
can easily infect several family members within a few days. It is often passed
on when the person touches the pus or discharge from the eye and then
touches someone else. What term best describes this kind of disease
transmission?
Indirect contact
Droplet contact
Direct contact
Vector
Droplet nuclei - -Direct contact
, - Vancomycin inhibits the formation of the bacterial cell wall, but it is not a
beta-lactam antibiotic.
True
False - -True
- In a measles infection, the rash fades in the same order that it appeared,
from head to extremities. What phase of an infectious disease is
demonstrated by this description?
Decline
Prodrome
Convalescence
Incubation
Clinical - -Decline
- Agents that might be used for acts of bioterrorism are categorized as
which class of agents by the NIAID?
Group I
Group II
Group III - -Group III
- The penicillin, penicillin G, was delivered to a patient either intravenously
or intramuscularly. What was it about penicillin V that made it such a more
useful antibiotic?
It was better than cephalosporin antibiotics.
It is acid stable and so could be taken orally.
It was resistant to penicillinase or beta-lactamase enzymes.
It could be used to treat a greater spectrum of bacterial infections - -It is
acid stable and so could be taken orally.
- Ciprofloxacin is a fluoroquinolone antibiotic that inhibits DNA gyrase. It is a
dangerous antibiotic to humans because it does not reach high blood levels
with oral absorption.
True
False - -False
- The primary use of Koch's postulates is to
Demonstrate that a disease is caused by a specific microorganism
Develop vaccines for specific diseases
Isolate microorganisms from diseased animals
Cleary identify and characterize a particular organism - -Demonstrate that a
disease is caused by a specific microorganism
- Clindamycin is a macrolide antibiotic and, consequently, inhibits the small
ribosomal subunit.
True
False - -False
