The endospore staining technique is a differential staining method. This method helps in the detection of endospore-containing bacteria, thus help in the classification of bacterial cells. Some bacterial cells have the ability to convert themselves into endospores in extreme environmental conditions. Endospore Stain Endospores are dormant forms of living bacteria and should not be confused with reproductive spores produced by fungi. These structures are produced by a few genera of Gram-positive bacteria, almost all bacilli, in response to adverse environmental conditions. Two common bacteria that produce endospores are Bacillus or Clostridum.

DISCUSSION. A few genera of bacteria, such as Bacillus, Clostridium and Clostridioides have the ability to produce resistant survival forms termed endospores.Unlike the reproductive spores of fungi and plants, these endospores are resistant to heat, drying, radiation, and various chemical disinfectants (see Labs 17 and 18) The ENDOSPORE STAIN was developed for the rod-shaped GENERA BACILLUS (aerobic) & CLOSTRIDIUM (anaerobic) as well as a for few other rare Genera with endospores. ENOSPORES are extreme structures! They are almost impossible to destroy!

While the rest of a bacterial cell may stain, the endospore is left colourless. To combat this, a special stain technique called a Moeller stain is used. That allows the endospore to show up as red, while the rest of the cell stains blue.

Once stained, however, endospores are equally hard to decolorize. The endospore stain is a differential stain because it differentiates spore-formers from non spore-formers. Note: Formation of an endospore.

Perform a bacterial smear of Bacillus or the organism you want to stain, as discussed in Figure 3-52 on page 150 of your lab manual. 2. Place a small piece of bibulous paper over the smear. Saturate the paper with malachite green.

Within bacteria, endospores are protective structures used to survive extreme conditions, but this protective nature makes them difficult to stain using normal techniques such as simple staining and Gram staining . Procedure of endospore stain Prepare smears of organisms to be tested for the presence of endospores on a clean microscope slide and air dry it. Heat fix the smear.

Endospores are formed by a few genera of bacteria, such as Bacillus. By forming spores, bacteria can survive in hostile conditions.
