Antibiotic Sensitivity

Antibiotic Sensitivity Lab

A.  Write a lab report about the Antibiotic Sensitivity−Kirby-Bauer Diffusion Test experiment in which you do the following:

1.  Explain why selective toxicity is an important feature of antibiotics.

a.  Discuss the relative benefits of broad-spectrum and narrow-spectrum antibiotics.

 Note:

The explanation from part A1 and discussion from part A1a belong in the introduction section of the lab report.
2.  Describe the steps you followed to complete the Kirby-Bauer diffusion test.

Note

Include any changes from the normal protocol that might have been incorporated into your experiment.

The description from part A2 belongs in the materials and methods section of the lab report.
3.  Record the observed results of the Kirby-Bauer diffusion test, including the zone of inhibition measurement and interpretation (e.g., resistant, intermediate, susceptible) for each antibiotic using the attached “Data Table.”

Note:

The explanation from part A3 belongs in the results section of the lab report.
4.  Based on your recorded results from the Kirby-Bauer diffusion test, explain whether each of the following antibiotics would be a reasonable choice for treating S. epidermidis:

•  penicillin

•  novobiocin

•  gentamicin
Instructions:

The explanation from part A4 belongs in the discussion section of the lab report.
