  2. Endospore - Wikipedia

    en.wikipedia.org/wiki/Endospore

    Subterminal endospores are those between these two extremes, usually seen far enough towards the poles but close enough to the center so as not to be considered either terminal or central. Lateral endospores are seen occasionally. Examples of bacteria having terminal endospores include Clostridium tetani, the pathogen that causes the disease ...

  3. Endospore staining - Wikipedia

    en.wikipedia.org/wiki/Endospore_staining

    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 resistant to chemicals. [ 2 ]

  4. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    Detects the presence of endospores in six genera of bacteria Endospores: Green Vegetative cells: Red 6 Capsule A: Hiss method (Positive technique) B: Manevals's technique (Negative) Smear stained with Hiss stain following treatment with copper sulphate Bacterial suspension smeared along with Congo red and the Maneval's stain is applied

  5. Exosporium - Wikipedia

    en.wikipedia.org/wiki/Exosporium

    Some bacteria also produce endospores with an exosporium, of which the most commonly studied are Bacillus species, particularly Bacillus cereus and the anthrax-causing bacterium Bacillus anthracis. The exosporium is the portion of the spore that interacts with the environment or host organism, and may contain spore antigens. [1]

  6. Sporulation in Bacillus subtilis - Wikipedia

    en.wikipedia.org/wiki/Sporulation_in_Bacillus...

    The wrong decision can be catastrophic: a vegetative cell will die if the conditions are too harsh, while bacteria forming spores in an environment which is conducive to vegetative growth will be out competed. [3] In short, initiation of sporulation is a very tightly regulated network with numerous checkpoints for efficient control. [citation ...

  7. Sporogenesis - Wikipedia

    en.wikipedia.org/wiki/Sporogenesis

    The term sporogenesis can also refer to endospore formation in bacteria, which allows the cells to survive unfavorable conditions. Endospores are not reproductive structures and their formation does not require cell fusion or division. Instead, they form through the production of an encapsulating spore coat within the spore-forming cell.

  9. Schaeffer–Fulton stain - Wikipedia

    en.wikipedia.org/wiki/Schaeffer–Fulton_stain

    A stained preparation of Bacillus subtilis showing endospores as green and the vegetative cell as red. The Schaeffer–Fulton stain is a technique designed to isolate endospores by staining any present endospores green, and any other bacterial bodies red. [1]
