Eosinophils. Literally 'eosin lovers'. Eosin the red dye in your question.
eosinophil
metachromatic granules are polyphosphate granules found in Corynebacterium diphtheriae. They have the property of taking up a stain and exhibiting a different colour - metachromatia. thus they take up malachite green and appear dark blue in colour.
Positive staining allows the bacteria to be directly stained and visualized under a microscope, which helps in studying their size, shape, and arrangement. It also provides valuable information about the cell wall structure and composition. Negative staining, on the other hand, allows the visualization of bacteria that are otherwise difficult to stain due to their thin or delicate cell walls. It provides better contrast and allows for the observation of fine morphological details of the bacteria.
Plant cells, animal cells and bacteria can be visualized through the light microscope. Although some of these samples may require staining in order for the observer to see them, the magnification offered by the light microscope is sufficient to look at the morphological structures of the types of cells mentioned above
If after staining, a smear reveals both purple(Gram +) and red cells(Gram -). This is generally an indication that the smear contains gram positive cells.
The description matches eosinophils, a type of white blood cell. Eosinophils are characterized by dark-staining granules that can be visualized under a microscope by basic dyes such as eosin. They play a role in allergies and parasitic infections.
That would be a Neutrophil. :)

The Ziehl-Neelsen stain is also known as the acid-fast stain. It contains sulfuric acid, and is used to identify acid-fast bacteria, or bacteria resistant to decolorization by acids from staining.

1- What_is_the_different_staining_technique_in_virology2- What are the diffrent stain in micro for virus ?
Staining is a chemical process.
No. It is a staining on the cell itself.
