Gram stainDefinitionThe Gram stain test is the most extensively performed procedure in diagnostic microbiology. It is used to classify bacteria as either gram-positive or gram-negative based upon their ability to retain the crystal violet stain following decolorization. In addition, the Gram stain provides vital diagnostic information, aids in the selection of culture media, and dictates.

Streptococcus is a genus of gram-positive coccus (plural cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Firmicutes.
