Sections A − C show the elliptical zone of inhibition of three S . pneumoniae strains around ceftazidime MIC strip, with MIC =32, 16 and 6 μg/ml of ceftazidime, respectively. In Part D and E, antibiotic susceptibility assay plates using Etest strips for penicillin, vancomycin, ceftazidime, ceftriaxone and ciprofloxacin are shown for two S. pneumoniae strains. Arrays in part D and E are shown the vancomycin MIC = 1.5 and 4 μg/ml respectively.
