1. A more standardized protocol for the Kirby-Bauer Method that allows for greater reliability in results would be to use : (a) agar plate media poured to a specific depth, and (b) bacterial cultures of specific cell densities (MacFarland standards). True or False?2. Staphylococcus aureus strain shows sensitivity to penicillin as demonstrated by the Kirby-Bauer method, One can correctly assume based on this result, that all Staphylococcus aureus strains would be sensitive to penicillin. True or False?3. Which of the following among A - D is not applicable to the Kirby-Bauer Method?A.It is a laboratory method to assess the sensitivity of bacterial strains to antibiotics.B.It utilizes the quadrant streak plate method to assess bacterial growth in the presence of antibiotic.C.Several antibiotics can be tested on a single culture plate.D.Results of the test can determine whether then bacterial strain is resistant, sensitive, or has intermediate sensitivity.E.A - D are all applicable to the Kirby-Bauer Method.4. The results of the Kirby-Bauer method of assessing antibiotic sensitivity can indicate whether or not the antibiotic has a bactericidal or bacteriostatic effect. True or False5. In the Kirby-Bauer method, the zone of inhibitionA.is a measure of the circumference of the circle surrounding the antibiotic disk.B.is smallest in diameter for bacteria that are most sensitive to the antibiotic (i.e., least resistant)C.is an area where no bacterial growth appearsD.all the above
