Here are the pictures of the bacteria we were able to locate in the slides!

Rod Shaped Bacteria; Gram Negative

Spiral Shaped Bacteria; Gram Negative

Circle Shaped Bacteria; Gram Positive

Gram Negative bacteria appear reddish-pink in the microscope, and Gram Positive appear more purple.  Gram Positive bacteria have more peptidoglycan  in their cell walls, and Gram Negative bacteria have less peptidoglycan in their cell walls.
