Question

4. Using your textbook or ot er references, match cach of the ancimicrobual agents listed in Table 25 I with its type and method of action. Type of Antimicrobial Agent a. Aminoglycosides E Monobactams b. ?-lactams c. Carbapenems d. Cephalosporins i Tetracyclines e. Glycopeptides k. None of the above fMacrolides Method of Action 1. Enzyme inhibitor 2. Inhibit cell wall synthesis 3. Inhibit protein synchesis h. Quinolones t Sulfonamides Method of Action Type Ampicillin Aztreonam Bacitracirn Ceftazidime Chloramphenicol Ciprofloxacin Erythromycin Imipenem Penicillin G Streptomycirn Sulfisoxazole Tetracycline Trimethoprim/Sulfamethoxazole Vancomycin

Explanation / Answer

Ampicillin - beta lactum - inhibits cell wall synthesis

Aztreonam - beta lactum - inhibits cell wall synthesis

Bacitracin - glycopeptides - inhibits cell wall synthesis.

Ceftazidime - beta lactum - inhibits cell wall synthesis.

Chloramphenicol - none of the above ( man made antibiotic) - inhibits protein synthesis.

Ciprofloxacin - quinolones - ciprofloxacin inhibits DNA replication and thus inhibits protein synthesis.

Erythromycin - macrolids - inhibits protein synthesis.

Imipenem - carbapenems - inhibits cell wall synthesis

Penicillin G - beta lactum - inhibits cell wall synthesis

Streptomycin - Aminoglycosides - inhibits protein synthesis.

Sulfisoxasol - sulfonamide - inhibits folic acid biosynthetic pathway by binding with PABA.

Tetracycline - none of above - inhibits protein synthesis.

Trimethoprim - sulfonamide - Inhibits DNA synthesis.

Vancomycin - glycopeptides - inhibits cell wall synthesis.
