Ø The classically used stain to visualize endospore is Malachite Green and the staining procedure is known as Schaeffer–Fulton Staining. Ø The endospore-producing mother cell is called sporangium. Endospores are quite resistant to most staining procedures; however, in a routinely stained smear, they may be visible as “outlines” with clear space within. Step-by-step video and audio instructions on how to endospore stain a slide that includes three bacterial smears; an endospore + control (known endospore pro Endospore stain procedure - YouTube. Endospore stains require heat to drive the stain into the cells.

Why is it necessary to perform an endospore stain to identify Clostridium for the endospore stain? *Green (spores) and *pink/red (vegetative cells). During the Endospore stains, capsule stains, and flagellar stains are staining techniques that allow for the differentiation of specific bacterial structures found either inside or The Schaeffer-Fulton endospore stain was modified so that it would stain Bacillus The modified stain differentiated among dormant spores, spores undergoing Examine a non-pathogenic bacterial strain that illustrates endospore formation. Select from an extensive catalog of educational tools available for enhancing the Jan 5, 2018 THE ENDOSPORE STAIN A differential staining technique is used to distinguish between the vegetative cells and the endospores.

Spores are resistant to heat, dessication, chemicals, and radiation. The procedure for differentially staining endospores and vegetative cells is as follows: Place the heat-fixed bacterial slide over screened water bath and then apply the primary stain malachite green. Allow the slide to sit over the steaming water bath for 5 minutes, reapplying stain if it begins to dry out. The standard endospore stain is a vigorous staining procedure using Malachite(măl' -К- kīt') Green as the main stain and Safranin as a counter stain (other counter stains may be used but we will ignore them for simplicity). Endospores are Endospore Stain.
By forming spores, bacteria can survive in hostile conditions. Spores are resistant to heat, dessication, chemicals, and radiation.

The most important endospore-forming bacteria are members of the genera Bacillus and Clostridium, both of which are Gram-positive rods. An endospore is a dense, multilayered structure that contains the genetic material of the bacterial cell. Endospore stain is the fourth staining method used to add contrast.
