Gram-negative bacteria are those bacteria that do not retain crystal violet dye in the Gram staining protocol. In a Gram stain test, a counter stain (commonly

STAINING AND BACTERIAL CELL MORPHOLOGY I. …

Reagents of Gram Stain Because the Gram stain reaction is more widely used and studied than any other stain, it is also the most open to variation in protocol. Four reagents are used in the Gram procedure: 1. A primary stain--originally aniline-gentian violet was used, but this has been replaced by the more stable crystal violet. 2.

Isolation &Characterization of Bacteria

The primary stain used in this kit for the Gram staining is crystal violet; however methylene blue isan adequate substitute. The microorganisms (bacteria) that retain the primary crystal violet stain appear as apurple brown color under the microscope.The stained bacteria are referred to as Gram rpositive .
