1: cells may produce an enzyme that destroys ordeactivates the drug. 2: slow or prevent the entry of thedrug into the cell 3: alter the target of the drug so that thedrug either cannot attach to it or binds it less effectively 4: Alter their metabolic chemistry, or theymay abandon the sensitive metabolic step altogether 5: Pump the antimicrobial out of the cellbefore the drug can act 6: Bacteria within biofilms resist antimicrobials more effectivelythan free-living cells 7: protecting the target of an antimicrobial drug |
