Homework Answers
ANSWER:
The area around every antibiotic plate indicates the lethality of that antibiotic on the bacteria in question.
As the antimicrobic diffuses through the media, the highest lenel of antimicrobic is the area most closest to the antimicrobic disk. More away we go from the antimicrobic disk, lesser is the concentration of the antimicrobic.
The gradient area where the growth of a microorganism is prevented is called the ZONE OF INHIBITION.

Background
Questions
Bacteria in the environment must be controlled to reduce the chance of spreading the bacteria and possible infectious disease. There are many methods of controlling bacterial numbers; heat, chemicals, drugs and radiation are a few. Each control method targets something within the cell either structurally or metabolically that leads to cellular death. Microbes are most vulnerable during the exponential growth phase, when there is a high level of metabolism and cellular structures are being created. Many control methods...

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...
