It can, but due to the high agar content of MacConkey agar the swarming is slow and restricted. So it is usually quite easy to select non-Proteus colonies for sub-culture if done within 24 hours of incubation.
Yes..Incubate at 36-370C for 24 hours-48 hours
Gamma
types macconkey agar
Lac+ bacteria is acid base color indicator that lowers the pH of the MacConkey agar. The MacConkey agar contains neutral red dye, lactose, peptone, and crystal violet dye.
Colorless, it doesnt ferment lactose.

MacConkey agar
MacConkey agar is solid at room temperature because it is a gel-like polysaccharide. Broth that has 1.5 percent agar in it and is heated up will become a liquid.
