Gram stain spore
WebBacterial sporesare small oval or spherical structures that are very resistant to high temperatures, radiation, desiccation, and chemical agents. When they are formed intracellularly, they are called endospore. The bacterial cell producing spore is called vegetative cell. The spore is formed as a response to adverse conditions. WebThe spore is stained green and the vegetative cell is stained a pinkish red color. Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly ...
