Label the image to review major targets of drugs acting on bacterial cells. Cephalosporins Protein synthesis inhibitors acting on ribosomes Cell membrane Sulfonamides (sulfa drugs) Cell wall inhibitors Penicillins Polymyxins Erythromycin Aminoglycosides Quinolones Folic acid synthesis DNA/RNA Rifampin
Which two antimicrobial drugs inhibit sequential steps in the synthesis of folic acid? penicillin and sulfamethoxazole sulfamethoxazole and trimethoprim penicillin and gentamicin erythromycin and penicillin trimethoprim and synercid True/False: Viral infections are generally easier to treat than bacterial infections because viruses do not have a cellular structure. True False 1. Superinfection is most likely to result from a narrow spectrum antibiotic an extremely invasive, pathogenic organism that is antibiotic resistant the same organism re-infecting a patient after discontinuing antibiotic therapy...
Please answer all... Thank you!
Options: block specific metabolic reactions (competitive
analogs), deterioration of a cell membrane (perhaps concomitant
with some cell wall damage), inhibit cell synthesis, inhibits DNA
synthesis, interfere with protein synthesis
(11 pts) 104) Identify the modes of action with the general antibiotic/chemotherapeutic categories. Only one answer is correct per agent Aminoglycosides Select One Antifungal Select One antibiotics Cephalosporins Select One Chloramphenicol Select One Erythromycin Select One Isonicotinic acid Select One hydrazide (Isoniazide) Nalidixic acid Select One...
Zithromycin inhibits protein synthesis in bacteria. However, it cannot cross gram-negative bacteria cell walls. Would you expect zithromycin to be broad or narrow spectrum? Why? Amphotericin B disrupts the plasma membrane by binding to sterols. Why can’t it be used to treat bacterial infections? Match the following processes with the statements listed below. (Answers may be used more than once.) a. transcription b. translation c. DNA replication Ciprofloxacin inhibits DNA helicase. Which process is inhibited? _______________ RCT is a nucleotide substitute for uracil. Which process is inhibited? ___________ Tetracycline...

Acyclovir A) are metabolic analogs of PABA and block folic acid synthesis B) inhibits the DNA polymerase of herpesvirus C) block transpeptidases that cross-link peptidoglycan molecules D) attach to the 30S ribosomal subunit and disrupt protein synthesis in the 70S ribosome E) binds to fungal ergosterol

Briefly explain how each of the following mechanisms of action inhibits or kills bacteria and give examples of each: Inhibition of cell wall biosynthesis Inhibition of protein synthesis Inhibition of membrane function. Inhibition of nucleic acid synthesis Inhibition of metabolic pathways Inhibition of ATP synthase
When the term parenteral is used in regards to drug administration, this applies to drugs administered _____ (choose all that apply). Select one or more: a. intravenously b. orally c. intramuscularly d. topically Protein synthesis occurs in all living cells. Why, then, are some antimicrobial drugs that target protein synthesis selectively toxic to bacteria? Select one: a. The protein synthesis in human cells occurs less frequently than that in bacterial cells. b. The ribosomes found in human cells and those...
All of the following are true statements concerning plasmids EXCEPT: A)They can carry genes that confer resistance against antibiotics B)They can be found in bacteria, fungi, and protozoa C)They carry genes that are required for growth and repair D)They are small circular molecules of DNA. E)They can replicate autonomously -------------------- 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...
