Half Answer: There are both Gram positive and Gram negative stains that are used to identify different types of Bacteria. They depend upon 'membrane content' - some stains highlight only the nuclear envelope.
A gram stain is a cow
Lactococcus Lactus is a gram positive bacteria and therefore retains the darker staining and therefore shows on a gram stain as dark blue/violet colour. This is because the thick peptidoglycan cell wall retains the primary crystal violet stain.
Protists are often stained using a silver stain, not a Gram stain.
to determine a type of bacteria. This question is very vague. I will assume they are doing surgery on something that is infected and to help identify the the bacteria causing the infection, gram stain would be ordered.
The four possible results after Gram staining are Gram positive, Gram negative, Gram variable and Gram in-determinant.

The gram stain uses a decolorizing product so it is possible to differentiate between the gram and the gram cells. Gram positive cells stain purple in color.
A negative result for the spores stain indicate that the gram-negative organism is present. A positive result for a spore stain indicates that a gram positive organism is present.

There are producer and consumer eubacteria. While cyanobacteria produces its own food, there are two different types of consumer eubacteria, which are the gram-positive and gram-negative eubacteria. This bacteria type obtain energy by eating other organisms.
The Gram stain is used for bacteria and not for viruses.
