In most cases, Gram stains are performed on biopsy or bodily fluids when infection is suspected, and they yield results much more quickly than other methods, such as culturing. Staining is a term that describes the epithelial disruption and other pathophysiologic changes observed when using topical dyes--also referred to as vital stains. . What are the advantages of a direct stain? Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample. Then you will have to classify the cells depending on the shape/number of nuclei. One goal in making smears is learning to recognize the correct density of bacteria to put on the slide. 1. These microscopes have the capability to distinguish the details, properties, and features of any specimen up to a single nanometer small, or less. killed.
