Antibiotic Drugs Flashcards
It is also known as prokaryotes which are single-celled organisms that lack a true nucleus and nuclear membrane
Bacteria
It is the substances that inhibit bacterial growth or kill bacteria and other microorganisms
Antibacterial drugs (Antibiotics)
When bacteria is resistant to the drug = the pathogen will continue to grow despite administration
Resistance to Antibacterial Drugs
Equal to sum of the effects of two antibiotics
Additive Effect
It occurs when one antibiotic increases the effectiveness of the 2nd drug
Potentiative effect
When two drugs are used together; the desired effect may be greatly reduced
Antagonistic effect
NARROW AND BROAD SPECTRUM:
It is primarily effective against one type of organism (selective)
Narrow Spectrum
NARROW AND BROAD SPECTRUM:
it is effective against gram-positive and gram-negative organisms
Broad spectrum
It is when a drug selected is known to be the best drug that can kill the MO
Empiric therapy
It is when signs and symptoms do not improve
Subtherapeutic
It happens when the antibiotics completely eliminate the normal bacterial flora
Superinfection
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 therapy
In laboratory testing:
aspirated of the body fluid is examined under the microscope
Gram stain
In laboratory testing #2:
Aspirated is applied to a medium where they are grown for several days
Culture
In laboratory testing #3:
It is used to test for sensitivity of the organisms to various antimicrobials
Sensitivity
