order to recover Chlamydia spp? Answer: Inoculate cycloheximide
treated McCoy cells.
◉ Specimens for virus cultures should be transported in media
containing: Answer: Antibiotics and nutrients.
◉ The most sensitive method for the detection of Beta lactamase in
bacteria is the use of: Answer: Chromogenic cephalosporin.
, ◉ The breakpoint of an antimicrobial drug refers to: Answer: The
level of the drug that is achievable in serum.
An organism is susceptible if the M.I.C. is at or below the breakpoint.
◉ What class of antibiotics are used for the treatment of serious
gram negative infections as well as infections with Mycobacterium
tuberculosis? Answer: Aminoglycosides.
◉ How do Aminoglycosides work? Answer: By inhibiting protein
synthesis.
◉ What antibiotics are included in the Aminoglycosides? Answer:
Amikacin.
Gentamicin.
Tobramycin.
Kanamycin.
Streptomycin.
Spectinomycin.
◉ How are Aminoglycosides usually administered? Answer:
Intravenously or intramuscularly because they are poorly absorbed
from the gastrointestinal tract.
