What is Albert staining method?
Albert’s Metachromatic Stain demonstrates the presence of metachromatic granules found in Corynebacterium diphtheria. The granules stain purple-black against the light green counterstained cytoplasm. This helps to distinguish diphtheria from most of the short nonpathogenic diphtheroides which lack granules.

What is the other name of simple staining?
The term simple staining sometimes interchangeable with the terms like direct, positive or monochrome staining. Now let us understand why simple staining is called by such alternative names. Direct staining: Because it is a direct method that directly stains the bacterial cell with a colourless background.
What kind of stain is Albert stain?
differential stain
Albert’s stain was first described in 1920 and is a type of differential stain used for staining the volutin granules also known as metachromatic granules or food granules found in Corynebacterium diphtheriae.
Is Albert stain differential stain?
Albert stain is a type of differential stain used for staining high-molecular-weight polymers of polyphosphate known as metachromatic granules or volutin granules found in Corynebacterium diphtheriae.
What is KLB in microbiology?
Klebs loeffler bacilli (KLB), Corynebacterium Diphtheriae, Diagnosis and Stain, – Labpedia.net.
What are the staining procedures?
The performance of the Gram Stain on any sample requires 4 basic steps that include applying a primary stain (crystal violet) to a heat-fixed smear, followed by the addition of a mordant (Gram’s Iodine), rapid decolorization with alcohol, acetone, or a mixture of alcohol and acetone and lastly, counterstaining with …
What is simple staining procedure?
Simple staining involves directly staining the bacterial cell with a positively charged dye in order to see bacterial detail, in contrast to negative staining where the bacteria remain unstained against a dark background.
Why simple stains are called simple?
Welcome to Microbugz – Simple Stains. The simple stain can be used to determine cell shape, size, and arrangement. True to its name, the simple stain is a very simple staining procedure involving only one stain. You may choose from methylene blue, Gram safranin, and Gram crystal violet.
Why is Albert stain used?
Albert’s stain can be used for the presumptive diagnosis of diphtheria. Albert’s staining demonstrates the metachromatic granules in club-shaped C. diphtheriae bacilli, often arranged in Chinese character-like formations.
What is Spore staining in microbiology?
Abstract. Endospores staining is the type of staining to recognize the presence spore in bacterial vegetative cells. The bacterial endospores need a staining which can penetrate wall thickness of spore bacteria. A method of endospores staining is Schaeffer Fulton method that used Malachite Green.
What is Neisser stain used for?
The Neisser stain is a microbiological stain for visualising the polar bodies in the cytoplasm of gram-positive bacteria. This staining is used to identify diphtheria bacteria. Cells are stained with methylene blue and crystal violet in acidic solution and then counterstained with chrysoidin solution.
How many staining methods are there?
The types are: 1. Simple Staining 2. Differential Staining 3. Gram Staining 4.
Whats the meaning of stain?
1 : to suffuse with color. 2 : discolor, soil. 3a : taint sense 3 a conscience stained with guilt. b : to bring discredit on the scandal stained his reputation. 4 : to color (something, such as wood, glass, or cloth) by processes affecting chemically or otherwise the material itself.
What is monochromatic staining?
The use of single stain to colour the bacteria is commonly called as monochrome staining. (Mono-single, Chrome-color)The method of staining utilizes the knowledge that bacteria possess slight negative charge. The negative charged group of bacterial cell surface produces attraction between basic stains.
What is spore staining technique?
Endospore staining is a differential staining technique that selectively stains the spores and makes them distinguishable from the vegetative part of the cells. Endospores are produced by a few genera of Gram-positive bacilli such as Bacillus and Clostridium, in response to adverse environmental conditions.
What is differential staining technique?
Differential staining is a staining process which uses more than one chemical stain. Using multiple stains can better differentiate between different microorganisms or structures/cellular components of a single organism.
What does warthin Starry stain?
Warthin – Starry stain is a stain based on silver nitrate used in histology. This type of stain is commonly called silver staining. Warthin – Starry stain is used for the visualization of spirochetes but also for the detection of Helicobacter pylori and microsperediates.
What is bipolar staining?
A bipolar stain is a particular staining pattern that colours only the two opposite poles of the microorganism in question, leaving the rest of the bacterium unstained or a lighter colour.
