Gram Staining is the skill of using Crystal Violet, Gram's Iodine, and Safranin to help identify bacteria. Gram staining is usually one of the first steps in the full process of identifying bacteria. This procedure will help to tell you if a bacteria is gram positive or negative, what shape it is, and whether or not it can be treated with antibiotics. This skill is important in the bio-medical field when trying to determine what bacteria has infected a patient. Also, this skill is useful when deciding what a bacteria should be treated with.
