ANTIBIOTIC DRUGS Flashcards
known as prokaryotes which are single-celled organisms that lack a true nucleus and nuclear membrane
Bacteria
Substances that inhibit bacterial growth or kill bacteria and other microorganisms
Antibacterial drugs
equal to the sum of the effects of two antibiotics
Additive effect
occurs when one antibiotic increases the effectiveness of the 2nddrug
Potentiative affect
when two drugs are used together, the desired effect may be greatly reduced
Antagonist effect
when a drug selected is known to be the best drug that can kill the MO
Empiric theraphy
once the MO is identified in the lab, the antibiotic therapy is tailored by using the most narrow-spectrum, least toxic drug based on C&S results
Definitive theraphy
when signs and symptoms do not improve
Subtherapeutic
happens when antibiotics reduce or eliminate the normal bacterial flora
Superinfection
