What does the disk diffusion method measure?
The pH level of the culture broth.
The temperature of the agar medium.
The zone of inhibition.
The size of bacterial colonies.
What does MIC stand for?
Maximum Inhibitory Concentration
Minimum Infective Concentration
Minimum Inhibitory Concentration
Maximum Infective Concentration
Which of the following is used to determine the exact MIC value on an agar plate?
Disk diffusion
E-Test
Broth dilution
Automated systems
What is the primary role of antibiotic susceptibility testing?
To develop new antibiotics
To determine bacterial sensitivity to antibiotics
To measure antibiotic concentration in plasma
To measure the body's immune response
Which organization provide breakpoints for interpreting AST results?
WHO
CLSI
FDA
EUCAST
What is the main advantage of automated systems like VITEK 2?
Manual data recording
High cost-effectiveness
Reduced need for laboratory equipment
Rapid and standardized results
Which medium is commonly used in the disk diffusion method?
Blood agar
MacConkey agar
Mueller-Hinton agar
Sabouraud agar
The disk diffusion method is also known as the (a) test.
The lowest antibiotic concentration that inhibits visible bacterial growth is called (a) .
A (a) zone of inhibition in a disk diffusion test corresponds to increased bacterial resistance to the antibiotic.
If the MIC of an antibiotic is higher than the established breakpoint, or there is no inhibition zone on the Mulelr-Hinton plate, the bacteria are considered (a) to that antibiotic.
Explain the importance of antibiotic susceptibility testing in clinical practice and its role in combating antimicrobial resistance.
Compare and contrast the disk diffusion method and the broth dilution method for AST.
What is the purpose of the E-Test in antibiotic susceptibility testing?
To assess the pH of the medium
To identify bacterial species
To measure the growth rate of bacteria
To determine the minimum inhibitory concentration
Which of the following factors can influence the results of antibiotic susceptibility testing?
All of the above
Inoculum size
Temperature of the agar
Incubation time
What is the significance of the zone of inhibition in the disk diffusion method?
It shows the effectiveness of the antibiotic
It determines the size of bacterial colonies
It indicates the bacterial growth rate
It measures the pH of the agar
