- Please read the case file from exercise 25 (pg. 145). What information stood out to you after reading this? Why is it important for the antimicrobial susceptibility test to be performed? Please explain by using one of the patients from the case study to give support to your answer.How are dilution susceptibility tests and disc diffusion tests usedto determine microbial drug sensitivity?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
