Question

1. In Exercise 7-3 "Antimicrobial Susceptibility Test: Disk Diffusion (Kirby-Bauer) Method" several different microbes, including your El, were examined for their sensitivity to ciprofloxacin, penicillin, streptomycin and trimethoprim. For each of these drugs briefly describe its mode of action, in particular the bacterial target each drug acts upon and the specific effect that results from this interaction [Example: Azithromycin binds to the 50S ribosomal subunit in bacteria (target) and inhibits protein synthesis by blocking translocation of the ribosome during the elongation step of translation (specific effect)] Note that any reputable source (e.g., lab manual, MBIO 3813 textbook etc..) can be used to find this information.
