- A drug failed to work. Even if resistance is not an issue, the antimicrobials are found to only have a discrete range of bacteria that they can exert their effects on. Why is this the found case? Question options: Microbial components vary over different species and strains. If the organism naturally doesn't express the target component, the drug won't be able to exert an effect on it. Antimicrobials are designed to be effective for a predetermined period of time. An older antibiotic can't exert any effects on a new microbial strain. There is a different antimicrobial designed for every strain of bacteria. As a result there is no crossover in action due to selective targeting. The body filters antimicrobial compounds to interact with their target microorganism. Until research determines how to control this, antimicrobials will only ever have a very discrete range of targets.Which ONE of the following best describes the abbreviation ‘MIC’? Select one: A. The lowest concentration at which no microbial growth is detected B. The lowest concentration that indicates whether an antibiotic would be effective or not C. The lowest concentration which is not toxic to the host D. The lowest concentration which is least effective against the organism E. The lowest concentration which kills the organismwhich of the following definitions is not technically correct? a. broad spectrum - effective against many different types of microbes b. bacteriostatic - prevents microbes from growing c. antibiotic - microbial or synthetic product that kills or inhibits growth of microbes. d. all of the above are correct
- Which of the following is a consideration in treating bacterial infections A) Bacteriostatic b) bactericidal c) broad spectrumBroad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment choice? Broad-spectrum antimicrobials are usually toxic to the host cells. Broad-spectrum antimicrobials only work if they are used shortly after the infection begins. Broad-spectrum antimicrobials may kill much of the normal microbiota. Broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth. Broad-spectrum antimicrobials may stimulate excess growth of the normal microbiota.Which of the following is NOT a property of an antimicrobial agent? a. Must have a known concentration over a period of time required to eliminate a pathogen b. all choices are correct c. must be selectively toxic d. Must have a favorable chemotherapeutic index
- Explain how bacteria can become resistant to ampicillin. Be sure to mention the following terms: peptidoglycan, beta lactamase, transpeptidase, beta lactam.Differences between Gram + and – and examples. Describe at least two diseases for each, signs, symptomsWhich of the following factors is NOT significant in determining the effectiveness of a microbial treatment? Group of answer choices The toxins secreted by the microbe being treated. The susceptibility of the microbe to the treatment. The concentration of the treatment. The length of exposure to the treatment
- Which of the following is a true statement about the aminoglycosides? Multiple Choice They are a group of bacteriostatic antibiotics. Their antibacterial spectrum mainly includes gram-positive bacilli. They are active against anaerobic organisms. They cause irreversible inhibition of bacterial protein synthesis.Microbiology: Give an example of a microorganism showing Pathogenicity and an example of a microorganism showing high Virulence.Identify a correct statement about tetracyclines. Multiple Choice They have a narrow antibacterial spectrum. They are bactericidal in nature. They bind irreversibly to bacterial ribosomes to inhibit bacterial protein synthesis. Their widespread use has allowed the emergence of bacterial resistance.
