  4. Antibiotic susceptibility • The empty areas surrounding the discs show where antibiotics diffused into the agar and killed the bacteria or ? Complete the worksheet in groups and prepare to share your data with the class.

  5. Identifying antibiotic susceptibility of Staph Aureus Label the worksheet with the number of your MSA plate. Label each of the circles with the initials on the antibiotic disk. Draw a picture of the zone of inhibition (ZOI) around each circle Measure the diameter of the ZOI in millimeters and then record it on in the table. 1 6 2 5 3 4

  6. ZOIs from each lawn plate from MSA plate___:

  7. Compare different MSA plates: Susceptible >17mm Unsusceptible <13mm

  8. Wrap up • We used differential growth susceptibility to determine whether Staph Aureus grows in your nose. • Why might it be important to • know what is growing in your • nose? A B I C J K H D L G E F
