- What is the relationship between the zone of inhibition and antibiotic concentration and what is the most effective antibiotic based on this table?which antiseptic do you think will be most effective against the probiotic? Why?If a technician examined a Kirby-Bauer assay and found individualcolonies of the plated microbe growing within the zone of inhibitionfor a drug, what should her conclusion be?
- What does the zone of inhibition imply? Does the measurement of the zone ofinhibition imply that one antibiotic is better than the other? Support your answer.If cultures are suffering severely due to alkaloid production and accumulation in the medium then, how can i overcome this problem?The reason why most antibiotics as oral suspension dosage forms are commercially available as dry powders, to be reconstituted with water just prior to dispensing, is:
