This stain is used to visualize bacterial endospores produced by members of the genera Bacillus and Clostridium.The nature of the spore makes it impervious to most ordinary stains and staining methods, but, once stained it strongly resists decolorization and counterstaining. WebThe Gram stain is the most common differential stain used in microbiology. Differential stains use more than one dye. The unique cellular components of the bacteria will determine how they will react to the different dyes. The Gram stain procedure has been basically unchanged since it was first developed in 1884.
WebFor example, Gram staining can help clinicians classify bacterial pathogens in a sample into categories associated with specific properties. Gram-negative bacteria tend to be more resistant to certain antibiotics than gram-positive bacteria. We will discuss this and other applications of Gram staining in more detail in later chapters.
