Chemical modification of an antibiotic by bacteria would lead to a loss of function of the antibiotic. O True O False
The size of the inhibition zone depends on conditions such as: Multiple Choice The concentration of the antibiotic loaded onto the disk The solubility of the antibiotic availability of moisture The concentration of the antibiotic loaded onto the disk AND the solubility of the antibiotic
The clear zone around an antibiotic disk Multiple Choice is a plaque indicating the bacteria got killed is a zone of inhibition is a zone of inhibition indicating resistance of microbes is a zone of inhibition indicating susceptibility of microbes
Some bacteria produce the enzyme penicillinase, which breaks the beta-lactam ring in the penicillin molecule and converts it into penicilloic acid, which is harmless to bacteria. This is an example of which of the following mechanisms of antibiotic resistance? which option below is the answer? Destruction or inactivation of the antibiotic by the microbe Preventing penetration to the target site within the microbe Alteration of the drug’s target site(s) within the microbe None of the other four answers are correct Rapid ejection (pumping) of the drug out of the microbial cell
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.
