   Gram-negative
   Gram-negative: Gram-negative bacteria lose the crystal violet stain (and take the color of the red counterstain) in Gram's method of staining. This is characteristic of bacteria that have a cell wall composed of a thin layer of a particular substance (called peptidoglycan). The Gram-negative bacteria include most of the bacteria normally found in t ...

   Gram-negative
   Refers to the inability of a bacterium to resist decolorization with alcohol after being treated with Gram crystal violet. However, following decolorization, these bacteria can be readily counterstained with safranin, imparting a pink or red color to the bacterium when viewed by light microscopy. This reaction is usually an indication that the oute...

   Gram-Positive-Negative
   Gram's Method is a staining procedure that separates bacteria into those that stain (positive) and those that don't (negative).

This is significant to the microbiologist and the pathologist; oth ...
