Simple Stain: A simple stain consists of a solution of a single dye. Some of the most commonly used dyes are methylene blue, basic fuchsin, and crystal violet. Simple stains allow one to distinguish the shape (morphology) of the bacteria. For example, E. coli and Bacillus Subtillus are bacilli or rod-shaped bacteria. Many bacilli occur singularly, but chains may also be observed. Bacilli vary greatly in length and diameter. Staphylococcus aureus and Streptococcus pneumoniae are cocci or spherical bacteria. Cocci may occur singularly, in pairs (as in Streptococcus pneumoniae), or in clusters (as in Staphylococcus aureus). R. rubrum is a spirillum or curved bacterium, Spirilla always occur singularly.
This professional stain is stored in a 30ml polyethelyne dropping bottle for easy use.
