Question

assess the following descriptions, and classify them according to their respective staining type. minimizes shrinkage and distortion of cells; cells repel stain and appear colorless; capsule stain with nigrosin; useful to quickly determine cell size and shape; used to detect mycobacterium tuberculosis in sputum samples; uses a single dye; uses primary dye and counterstain; cells with lipopolysaccharide (lps) stain pink. categories: negative, differential, simple.

Explanation:

To solve this, we analyze each description and match it to the staining type (Negative, Differential, Simple) based on staining principles:

Negative Staining

• cells repel stain and appear colorless: In negative staining, the background is stained, and cells (hydrophobic or with repelling structures) remain colorless.
• capsule stain with nigrosin: Nigrosin is a negative stain; it colors the background, leaving capsules (and cells) unstained/colorless.

Differential Staining

• *used to detect Mycobacterium tuberculosis in sputum samples: Acid - fast staining (a differential stain) is used for Mycobacterium*.
• uses primary dye and counterstain: Differential stains (e.g., Gram, acid - fast) use a primary dye and a counterstain to differentiate cell types.
• cells with lipopolysaccharide (LPS) stain pink: In Gram staining (differential), Gram - negative bacteria (with LPS) take up the counterstain (safranin) and appear pink.

Simple Staining

• minimizes shrinkage and distortion of cells: Simple stains (using basic dyes) are gentle and reduce cell distortion.
• useful to quickly determine cell size and shape: Simple staining (one dye) allows quick visualization of cell morphology.
• uses a single dye: By definition, simple staining uses only one dye to color cells.

Final Classification Table

Staining Type	Descriptions
Differential	used to detect Mycobacterium tuberculosis in sputum samples; uses primary dye and counterstain; cells with lipopolysaccharide (LPS) stain pink
Simple	minimizes shrinkage and distortion of cells; useful to quickly determine cell size and shape; uses a single dye
