Negative staining is also known as indirect staining because the stain does not directly interact with the specimen.
Gram Negative
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.
Enterobacter cloacae is a Gram-negative bacterium. It will stain pink or red in a Gram stain procedure.
The answer to whether HIV gram-stain positive or negative is that HIV gram-stain is negative. They retain the light red or pink color after the stain.
The purpose of using the primary stain in the process of gram staining is to colorize the bacterial cells, allowing them to be differentiated based on their cell wall composition. This helps to classify the bacteria as either gram-positive or gram-negative.
The decolorizer, usually acetone or alcohol, is used to wash the Crystal Violet stain from the Gram Negative cells. From this point Safranin stain is used to stain the Gram Negative cells. The final color for Gram Negative will be a Red/Pink color.
The purpose of using pre-stain wood conditioner before applying stain to wood is to help the wood absorb the stain more evenly and prevent blotchiness or uneven coloration.
Negative
Gram staining is a simple staining test that simply identifies the two main groups of bacteria. Gram positive, and gram negative. Down a microscope, gram pos look like a dark blue/purple colour, and gram neg look red. It is to do with what the wall of the bacteria comprises of, and without going into too much detail, certain drugs work on gram pos bacteria, and others wont. Likewise for gram neg.
