ANTIBIOTIC DRUGS Flashcards
Also known as prokaryotes which are single celled organisms that lack a true nucleus and nuclear membrane.
Bacteria
Who devised a method to classify bacteria using Gram-stain method?
Hans Christian Gram
It is substances that inhibit- bacterial growth or kill bacteria and other microorganisms.
Antibacterial Drugs
Who discovered penicillin, the first antibiotic drug that was used and marketed?
Alexander Fleming
What is the difference between antiseptics and disinfectants?
Antiseptics are used in living tissue, while disinfectants are used in non-living objects.
What happens if the bacteria is drug-sensitive?
The pathogen can be inhibited or destroyed.
What will happen when the bacteria are resistant to drugs?
The pathogen will continue to grow despite administration.
It is equal to the sum of the effects of two antibiotics.
Additive Effect
It occurs when one antibiotic increases the effectiveness of the second drug.
Potentiative Effect
What do you call it when two drugs are used together? the desired effect may be greatly reduced.
Antagonistic Effect
It is effective against gram-positive and gram-negative organisms.
Broad Spectrum
It is primarily effective against one type of organism (selective).
Narrow Spectrum
It happens when a drug is selected that is known to be the best one that can kill the MO.
Empiric Therapy
When signs and symptoms do not improve.
Subtherapeutic
Occurs when the antibiotics reduce or completely eliminate the normal bacterial flora
Superinfection
