Antibiotic = Antimicrobial agent produced by a microbe

Antimicrobial agent = any chemical that kills or inhibits growth of a microbe

Bacteriostatic no change (frozen)

Bactericidal it will kill the inner cell

Bacteriolytic kills the cell

No target structure

can inactive the microbial

pump out the microbial

MRSA

penacilin

PBP2a different structure

can work with the presence of penacilin

Penicillin

inhibits peptidoglycan cell wall sythe synthesis

Enzyme = PBP

Natural substance

Binds irreversible

transpeptidase

similar structure as B-lactam rings

causes reduced cross-linking weak

large family similar

MIC = smallest amout of agent required to ihibit growth

conditions need to be controlled

E-Test

uses a conc gradient of antimicrobial
