Disinfection, desiccation, filtration, fridge, heat, radiation, and Sterilization correct answers
Types of sterilization/inhibition techniques
denatures proteins
15 lbs ,121*C for 15 mins correct answers Moist Heat Sterilization
kills by oxidation
hot air oven 170*C for 2 hrs correct answers dry heat sterilization
140*C for 3 secs, NOT STERILIZATION correct answers pasturization sterilization
Damages cytoplasmic membrane and denatures protein correct answers Disinfectant: Phenol
Oxidizes (iodine and chlorine) correct answers Disinfectant: Halogens
Denatures proteins and dissolves lipids correct answers Disinfectant: Alcohols
penicillins and cephalosporins
cell wall synthesis correct answers B Lactams
Vancomycin
C Diff/MRSA
cell wall synthesis correct answers Glycoproteins
Gentamycin, tobramycin correct answers Aminoglycosides
-Tetracycline, doxycycline, minocycline
-Clinical use: Borrelia burgdorferi, M. pneumoniae. Drugs' ability to accumulate intracellularly
makes them very effective against Rickettsia and Chlamydia. Also used to treat acne. correct
answers Tetracyclines
Meningitis (Haemophilus influenzae, Neisseria meningitidis, Streptococcus pneumoniae) and
Rocky Mountain spotted fever (Rickettsia rickettsii). correct answers Chloramphenicol
erythromycin, clarithromycin, azithromycin correct answers Macrolides
Ciprofloxacin, norfloxacin
, P aeruginosa correct answers Quinolines
UTI (Bactrim, sulfisoxazole)
Ulcerative colitis (Sulfasalazine)
folic acid metabolism correct answers Sulfa drugs
quinupristin/dalfopristin
vanco resistant E. Faecium correct answers Streptogramins
linezolid (Zyvox);
Used to treat methicillin resistant Staphylococcus aureus (MRSA) and vancomycin resistant
Enterococcus (VRE) correct answers Oxazolidinones
Aminoglycosides, cephalosporins, quinolones correct answers GNR Drugs
RNA metabolism correct answers Rifampin
killing harmful microbes without damaging the host correct answers selective toxicity
Kills bacteria without host immune help correct answers Bactericidal action
Inhibits organism growth correct answers Bacteriostatic action
the minimum concentration of a substance necessary to prevent microbial growth correct
answers Minimum inhibitory concentration (MIC)
minimum concentration of drug needed for killing of bacteria correct answers Minimum
bactericidal concentration (MBC)
Referring to a more resistant group of beta-lactamases that hydrolyze extended spectrum
cephalosporins w/ an *oxyimino side chain*
(abx ex: cefotaxime, ceftriaxone, ceftazidime, aztreonam) correct answers ESBL (extended
spectrum beta-lactamase)
Test used to detect inducible clindamycin resistance in staph and β-streptococci. Erythromycin
disk in placed next to clindamycin disk on std. disk diffusion plate. Flattening of the clind. zone
(D Shaped zone) between the two disks indicates inducible clindamycin resistance. correct
answers D Test
bacteria that have developed resistance to carbapenems, which are types of antibiotics
