Summary Introduction
To analyze:
The colourless colony isolated on MacConkey agar is Salmonella or Shigella
Introduction:
MacConkey agar acts as a differential medium for lactose fermenting bacterium and non-lactose fermenting bacterium. If the agar retains the red colour and the colonies are opaque, then they are lactose fermenters and if the agar is colourless and the colonies are translucent, then they are non-lactose fermenters.

Describe the appearance of an S. agalactiae colony grown on blood agar. Describe how that colony would differ in appearance from a colony of S. pyogenes.
Cells of Salmonella are peritrichously flagellated, those ofPseudomonas polarly flagellated, and those of Spirillumlophotrichously flagellated. Using a sketch, show how eachorganism would appear in a flagella stain.
