Antimicrobials Flashcards

1
Q

Macrolides

A 
Macrolides
Gram positive bacteria
Protein synthesis is inhibited by drug binding to receptors on the 50S ribosomal subunit and subsequent disruption of the growing peptide chain
Bacteriostatic
Ex: Erythromycin

Q

Aminoglycosides

A

“Aminoglycoside
Gram positive and negative bacteria (not anaerobic bacteria)
Inhibit protein synthesis by binding to 30S ribosomal subunit
Bacteriostatic (may reach bacteriocidal levels)
Ex. Gentamicin

Q

Beta-lactams

A

“Beta-lactam
Gram positive and negative bacteria (may vary with individual antibiotic)
Inhibit cell wall synthesis by binding enzymes involved in peptidoglycan production
Bacteriocidal
Ex. Cefazolin, Imipenem, Ampicillin, Piperacillin/Tazobactam combo (ties up beta lactamases so other antimicrobial can exert it’s affect)

A

“Glycopeptides
Gram positive and negative bacteria (topical treatment)
Inhibit bacteria cell wall synthesis, but does not bind to PBPs
