Exercise 52

From chapter 3, selective and differential media. This is a plate with blood agar on the top and MacConkey agar on the bottom. (You studied both of these agars in chapter 3.) It has been inoculated with samples from a wooden cutting board that had been exposed to a raw chicken carcass. Knowing what you know about the properties of these two agars, say as much as you can about the bacteria growing on them.
