WebFor β-lactams, bacterial resistance can involve the enzymatic hydrolysis of the β-lactam bond within the β-lactam ring of the drug molecule. Once the β-lactam bond is broken, the drug loses its antibacterial activity. This mechanism of resistance is mediated by β-lactamases, which are the most common mechanism of β-lactam resistance. j-mups 端末 問い合わせWebStudy with Quizlet and memorize flashcards containing terms like A chronic alcoholic, while out on a binge, became very confused and forgetful.
