- 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 indexarrow_forwardWhether an antimicrobial is broad spectrum or narrow spectrum depends on its mode of action. For the following 2 hypothetical drugs, predict whether they are broad spectrum or narrow spectrum. Explain your reasoning: 4. a. Drug A interferes with peptidoglycan synthesis - b.

Body developing immunity to the antibioticarrow_forwardThere are many bacterial-antimicrobial resistance combinations. Which one of the following is of maior international concern? a. Sulfonamide resistance in Neisseria meningitides b. Penicillin G resistance in N. gonorrhoeae C. Ampicillin resistance in H. influenza d. Erythromycin resistance in S. pyogenes (group A streptococci) e. Vancomycin resistance in S. aureusarrow_forwardBroad-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.arrow_forward
- The type of antimicrobial drug that would be most likely to have toxic effects in humans based on the premise of selective toxicity when treating microbial infection would be a drug that O 1) inhibits the synthesis of the cell wall O 2) inhibits metabolic pathways O 3) disrupts the cytoplasmic membrane 4) inhibits protein synthesis 5) All of the above have equal potential to be toxicarrow_forwardReviewing drug characteristics, choose an antimicrobial for each of the following situations (explain your choice): a. for an adult patient suffering from Mycoplasma pneumonia b. for a child with bacterial meningitis (drug must enter into cerebrospinal fl uid) c. for a patient who has chlamydiosis and an allergy to azithromycin d. for treating a child with Rocky Mountain spotted fever e. for PPNG drug-resistant gonorrheaarrow_forwardReviewing drug characteristics, choose an antimicrobial for each of the following situations (explain your choice): a. for an adult patient suffering from Mycoplasma pneumonia b. for a child with bacterial meningitis (drug must enter into cerebrospinal fl uid) c. for a patient who has chlamydiosis and an allergy to azithromycin d. for treating a child with Rocky Mountain spotted fever e. for PPNG drug-resistant gonorrheaarrow_forward
