Q 1. The susceptibility tests included in this unit are typically used to differentiate between Gram-positive cocci. Would you predict them to be an affective differential test for Gram-negative oganisms? Why or why not?

Q 2. Why is important to get a bacterial lawn rather than isolated colonies on the plate?

Q 3. Does the zone of inhibition's edge indicate the limit of antibacterial agent diffusion into the agar? Give reasons or evidence to support your answer.
