Which step of a gram stain can be omitted without affecting determination of the reaction?
you can omit the last step - the safranin counterstain
What is the counterstain in a spore stain?
the counter stain is safranin 0.5%
Why is the counter stain for gram stain procedure differ from the counter stain used for acid fast procedure?
Safranin
What counter stain is used in gram staining?
safranin
Describe the microscopic appearance of encapsulated streptococcus if stained with safranin?
Safranin (red) is used in gram staining and endospore staining as the secondary stain. Nigrosin is used in negative staining, staining only the background and not the bacteria. Therefore, the bacteria within the capsule would stain red from the safranin. (Like in endospore staining and negative gram staining, safranin would stain the bacteria red.) Nigrosin would stain the background of the organism just as it would in negative staining. Bacteria (within capsul): stained safranin red Capsule (outer layer of bacteria): clear Background of organism: stained dark with Nigrosin
What is safranin solution in science?
safranin is a biological stain used in histology n cytology
Is carbol fuchsin the same as safranin?
No. safranin is the classic stain used in gram staining. Concentrated Carbol Fushin is mainly used for the ZN staining procedure to stain organisms such as Vibrio cholerae and Cryptosporidium. Diluted Carbol Fushin can however be used as a replacement counterstain for Safranin in the gram stain.

What happens if you use gram stain on a virus?
Most likely nothing. The gram stain will only stain the peptidoglycan cell wall of bacteria. Most viruses have a protein coat called a capsid. The capsid will not take up either the crystal violet or the safranin of a Gram stain.
Why was safranin used for cheek cell?

Is safranin an acidic dye?
Sure, any basic stain can be used for simple, direct staining.

What color is E coli when stained?
If you are talking about a Gram Stain, then red. E. coli is Gram negative which means that Safranin will stain it red during a gram stain.
