A clinician conducted a Kirby-Bauer Test to determine the sensitivity of Micrococcus luteus isolated from a hospitalized patient. The results/ zone of inhibition are shown in table 1 below. The interpretive standards are shown in table 2. A. Compare the results to the interpretive standards. Indicate whether or not the bacterium tested is sensitive, intermediate, or resistant to each of the antibiotics tested. B. Based on these results, which antibiotic should be prescribed to treat the patient’s infection? Explain your reasoning. C. Based on these results, which antibiotic would be the worst choice? Explain your reasoning. Table 1: Results Antibiotic Zone of Inhibition (mm) Amoxicillin 10 mm Doxycycline 12 mm Ciprofloxacin 23 mm Tetracycline 13 mm Table 2: Interpretative Standards Antibiotic Sensitive Intermediate Resistant Amoxicillin
