Zones of growth inhibition = diameter of well plus zone of growth inhibition; diameter of well = 8 mm. The mean zone of inhibition was determined from three independent results (n) = 3; nd = not determined; na = no activity; SEM = standard error mean; Cipro = ciprofloxacin; Keto = ketoconazole; Conc. = concentration. PA = Pseudomonas aeruginosa; EC = Escherichia coli; SA = Staphylococcus aureus; BS = Bacillus subtilis; SP = Streptococcus pyogenes, KP = Klebsiella pneumoniae; EF = Enterococcus faecalis; ST = Salmonella typhi; CA = Candida albicans; AN = A. niger; AF = A. flavus; AT= A. tamari.
