- What are three public health measures that could reduce the probability that bacteria will develop resistance to antibiotics? Be specific in your description, and remember to include evidence to support your answer.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 cellA non-direct application of the study of microbes is vaccination. true or false ?
- Consider the concept of empirical anti-microbial therapy. Why would a sputum sample have been collected before antibiotic therapy was commenced?Identifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.List four mechanisms that bacteria have developed through mutation to resist antimicrobial drugs
- An advantage of a point-of-care (POC) test is that effective antibiotic therapy can begin without a delay of waiting for off-site laboratory results. detection of multiple infections is more likely. clinicians are able to diagnose diseases based on clinical signs and symptoms alone. health care workers have a lower risk of exposure to pathogens.The Kirby-Bauer method uses a plastic strip with a concentration gradient of an antibiotic called an Etest strip. True FalseList two features limiting the adaptation of nonvascularplants.
- Discuss the general principles of antibiotic therapy.Briefly discuss the potential impact on the antibiotic susceptibility testing results when different agar thicknesses are used across different laboratories. What would you suggest to ensure that results between testing laboratories are comparable.there are different methods to be used in order to control opportunistic infection and that includes cleaning, sanitizing, disinfecting, sterilizing... And that depends how they can be applied according to the area and level the health care worker or scientist is and the environment. Do you know how these methods of microbial growth are applied and where?
