Antibiotics Mode of Action

Question 1

Beta Lactams (Penicillins and Cephalosporins)

Answer 1

Inhibit bacteria cell wall biosynthesis

Question 2

Aminoglycosides (Streptomycin, Neomycin, Kanamycin, Paromomycin)

Answer 2

Inhibit synthesis of proteins by bacteria, leading to cell death

Question 3

Glycopeptides (Vancomycin, Teicoplanin)

Answer 3

Inhibit bacteria cell wall biosynthesis

Question 4

Ansamycins (Geldanamycin, Rifamycin, Naphthomycin)

Answer 4

Inhibit synthesis of RNA by bacteria, leading to cell death

Question 5

Streptogramins (Pristinamycin IIA, Pristinamycin IA)

Answer 5

Inhibit synthesis of proteins by bacteria, leading to cell death

Question 6

Sulfanomides (Prontosil, Sulfanilamide, Sulfadiazine, Sulfisoxazole)

Answer 6

Prevent bacterial growth and proliferation. Look for sulfa allergy!

Question 7

Tetracyclines (Tetracycline, Doxycycline, Limecycline, Oxytetracycline)

Answer 7

Inhibit synthesis of proteins by bacteria, preventing growth

Question 8

Macrolides (Erythromycin, clarithromycin, azithromycin)

Answer 8

Inhibit protein synthesis by bacteria, occasionally leading to cell death

Question 9

Oxazolidinones (Linezolid, Posizolid, Tedizolid, cycloserine)

Answer 9

Inhibit synthesis of proteins by bacteria, preventing growth

Question 10

Quinolones (Ciprofloxacin, Levofloxacin, Trovafloxacin)

Answer 10

Interfere with bacteria DNA replication and transcription

Question 11

Lipopeptides (Daptomycin, Surfactin)

Answer 11

Disrupt multiple cell membrane functions, leading to cell death
