First, use a wax pencil to draw a one on the microscopic lense slide to different each type of bacteria the is walk to it is in sampled.

If a straightforward stain of only one kind of bacteria, or solitary mixed sample of bacteria is being prepared, no separation is required.
Article Summary: In bespeak to see individual bacteria with a light microscope, a bacterial smear have to be attached come a slide and then stained. Below is the procedure.
