+ 3. The following results were obtained from a disk diffusion test for a strain of Escherichia coli. Chemotherapeutic A B Zone of inhibition (mm) 7 10 18 3 C D Which drug above (A, B, C, or D) is most effective against this E. coli strain? Which drug above (A, B, C, or D) is most effective against Staphylococcus aureus? Explain your answer. Ex. 17: Chemotherapeutic Agents Using the Antimicrobial Susceptibility Table on pg 62 in the lab manual, determine whether not the bacteria plated in this Kirby-Bauer test are resistant (R), intermediate (I), or susceptible (S). The bacterial species tested was Escherichia coli (Gram negative). Ciprofloxacin Diameter = 20 Streptomycin Diameter 30 Carbenicillin Diameter 17 + Erythromycin Diameter = 23 Novobiocin Diameter = 0 bacterial growth = disk with antibiotic (see labels) = no growth

1. Which, if, any of the drugs would you prescribe for a somewhat effective treatment of a patient infected with this test organism?

2. Which, if, any of the drugs would you not prescribe because they were ineffective in killing or inhibiting a patient infected with this test organism?

3. Briefly explain how you would determine if one of the above drugs was broad spectrum or if it was narrow spectrum.
