Bacterial Staining TechniqueStudent Workshops

Quick Information

Bacterial cells are challenging to view under the microscope due to their need for colour and contrast. Researchers have been using several types of stains to make these cells visible. These staining procedures help study the morphology, dimensions, cell size and arrangement of bacteria, thereby enabling successful identification. The Gram staining method is one of the most commonly used procedures that help differentiate between gram-positive and gram-negative bacteria.
