AIM : To perform gram staining of given sample. MATERIAL REQUIRED : Glass slides, bunsan burner , cotton , sample , microscope. REAGENTS REQUIRED: Crystal violet dye, iodine, alcohol (95% ethyl alcohol), saffranin dye PRINCIPLE: Gram staining is most widely staining technique used in m/o examination. It was discovered by Danish scientist and physician Hans Christain Joachin Gram in 1884. This technique differentiates bacteria in 2 groups i.e. Gram positive and Gram negative bacteria. The procedure is based on the ability of m/o to retain colour of the stain during Gram reaction. Gram negative bacteria are decolourised by alcohol losing the colour of primary stain , purple. Gram positive bacteria are not decolourised by alcohol and will remain as purple. After decolourisation stop , a counter stain is used to impart pink colour to the gram negative m/o. Gram positive bacteria have a thick mesh like cell wall which is made up of peptidoglycan (50-90%) of cell wall, which stain purple. Gram negative bacteria have a thinner layer of peptidoglycan (10% of cell wall) and lose the crystal violet iodine complex during decolourisation with alcohol rinse but retain the counter stain safarin thus appearing reddish or purple. STAIN REACTION : 1. Application of crystal violet to heat fixed smear : CV dissociates in aqueous solution into CV+ and Cl- ions. These two penetrate the cell wall and cell membrane of both gram positive and gram negative . CV+ interact with negative component of bacterial cell and stain it purple. 2. Addition of gram iodine : Iodine acts as a mordant and a trapping agent. A mordant is a substance that increase the affinity of cell wall for a stain by binding to primary stain , thus forming a insoluble complex that get trapped in cell. During the reaction CV-I compex is formed and all the cells turn purple. 3. Decolourization with ethyl alcohol : Alcohol dissolve the lipid outer membrane of gram negative bacteria, thus leaving the petidoglycan layer exposed and increase the porosity of cell wall. The CV-I complex is then washed away from the peptidoglycan layer leaving gram negative bacteria colourless.In gram positive bacteria , alcohol has dehydrating effect on cell wall causing cell wall to shrink , then CV-I complex get tightly bound into multi layered leaving the cell with purple colour. 4. Counter stain with safranin dye : The decolourised gram negative cell can be visible with a suitable counter stain which is usually positively charged safarnin, which stained it pin
