- You are given a MacConkey plate with lactose fermenters Escherichia coli, Enterobacter aerogenes, Klebsiella pneumonia. What test do you prefer to differentiate among them? (i.e. MRVP test, Triple Sugar Iron test, Simmon Citrate test)The plate below is a test of 7 different antibiotics against Enterobacter aerogenes. The center disc is Ciprofloxacin 15 micrograms) and the 24 hour extent of the Zone of Inhibition is the farther diameter. The one below it and slightly to the right is Chloramphenicol (30 micrograms) [see red arrow}. Give me the extent of the Zone of Inhibition in mm (yes, use a ruler and measure it at the size it comes up on your computer screen), then use the Standard Table and determine R, I, S for each. Antibiotic Zone of Inhibition (mm) R, I or S Drug target Ciprofloxacin Chloramphenicol Which of the 2 drugs is more selective and why?Microbial secondary metabolites are compounds produced by strains of certain microbial(antimicrobial agent).such as penicillin and cephalosporin.
