Document Summary
Chapter 37: principles of antimictrobial therapy: understand what is meant by selective toxicity. Selective toxicity = kill invading microorganisms but not the host cell: understand empiric vs. Empiric therapy: administration of drugs based on your experience. Cephalosporins fall under, and what category the flu vaccines fall under. A: known that there is no harm to the baby. B: most common to antibiotics because it"s not known to cause any birth defects or. C: not enough testing to know if there"s a risk or not. Bacteriostatic: just stops the growth of bacteria stops spread of infection. Bacteriocidal: kills the bacteria but not always used because it might stimulate. Beta lactam antibiotic cell wall inhibitors: inhibits gram (+) bacteria but some bacteria have developed resistance to penicillin by developing beta-lactamase. Moa: binds to transpeptidase during synthesis of peptidoglycan wall (causes cell lysis = dead bacteria: drugs, penicillin g, penicillin k, understand what beta-lactamase is, what penicillinase is, how penicillinase works, the.
