When is bacteria considered resistant to an antibiotic?
if the zone of inhibition has a very small diameter or no zone at all.
If given an image which will show the least resistance?
if the diameter around the labelled letter is LARGER. (larger circle around it).
Microbicidal
kill microorganisms
Microbiostatic
inhibit bacterial growth
Antiseptics
chemicals used on living tissues/body surface to destroy pathogens.
Disinfectant
destroys or removes pathogens from inanimate objects
What happens if the binding of RNA polymerase activity to DNA is inhibited and cannot create mRNA?
Transcription is impacted
Sterilization
complete removal or destruction of all viable organisms.
Antibiotics
antimicrobial agents used for fighting bacterial infections within the body. KILL OR INHIBIT growth of bacteria
What does it mean if the coefficient is greater than 1?
Then it is more efficient than phenol.
What does MIC measure?
the lowest concentration of an antibiotic that inhibits the visible growth of a microorganism after overnight incubation.
how can we inhibit translation?
by interfering with ribosomes which are in charge of protein SYNTHESIS/ or elongation factor
What inhibits replication?
interfering with cell wall synthesis/ or synthesis of nucleotides (building blocks of DNA)
