Example of bacteria for metachromatic granules?
Corynebacterium diphtheriae is an example of a bacterium that contains metachromatic granules. These granules are composed of polyphosphate polymers and are typically observed in the metachromatic staining method where the granules appear blue or purple when stained with methylene blue.
What cell has a bilobed nucleus and red staining granules that become abundant during allergies and parasitic infections?
Eosinophils are the cells with a bilobed nucleus and red staining granules. They are involved in immune responses to allergies and parasitic infections by releasing substances to combat these invaders.
What is gram stain of rotavirus?
Rotavirus is a non-enveloped virus that does not stain well with the traditional Gram stain method. Instead, it is typically visualized using specialized staining techniques like electron microscopy or immunofluorescence staining.
What are inclusions in microbiology?
In microbiology, inclusions are intracellular structures found within microbial cells that serve as storage sites for various substances. These can include nutrients, such as glycogen or lipids, and other compounds like polyphosphate or sulfur granules. Inclusions can be useful for energy reserves and metabolic processes, allowing microorganisms to adapt to changing environmental conditions. They can be visualized using specific staining techniques under a microscope.
Eosinophil is named for what color of stain of its granules?
Eosinophils are named for their affinity to the eosin dye, which stains their granules a bright pink or reddish color. This characteristic staining property allows for easy identification of eosinophils under a microscope. The granules contain various enzymes and mediators involved in immune responses, particularly in combating parasitic infections and in allergic reactions.
White blood cell with dark-staining granules that have an affinity for basic dyes?
The description matches eosinophils, a type of white blood cell. Eosinophils are characterized by dark-staining granules that can be visualized under a microscope by basic dyes such as eosin. They play a role in allergies and parasitic infections.

What leukocyte is formed in bone marrow and having neutral staining granules?
That would be a Neutrophil. :)
What cell has a bilobed nucleus and red staining granules that become abundant during allergies and parasitic infections?
Eosinophils are the cells with a bilobed nucleus and red staining granules. They are involved in immune responses to allergies and parasitic infections by releasing substances to combat these invaders.
What is amido black?
Amido black is a dye commonly used for staining proteins in electrophoresis gels. It binds specifically to proteins and can be visualized after staining to help identify the presence and quantity of proteins in a sample.
What are the gram reaction of mycobacterium?
Mycobacteria are typically Gram-positive, but their cell wall structure is unique and contains high lipid content, making them resistant to Gram staining. They are best visualized using acid-fast staining methods, such as the Ziehl-Neelsen or Kinyoun stains.
What is gram stain of rotavirus?
Rotavirus is a non-enveloped virus that does not stain well with the traditional Gram stain method. Instead, it is typically visualized using specialized staining techniques like electron microscopy or immunofluorescence staining.
What structures will intensely Stain by Iodine in a potato?
In a potato, the structures that will intensely stain by iodine are primarily the starch granules present in the cells. Iodine forms a blue-black complex with starch, making the granules easily visible under a microscope. Additionally, the cell walls may show some staining, but the most significant staining will be observed in the starch-containing areas.

What blood cell granules stain bright orange red when you use Wright's stain?
Eosinophils are the blood cells whose granules stain bright orange-red when using Wright's stain. This staining highlights their role in immune responses and inflammation.

What is silver impregnation staining?
Silver impregnation staining is a histological technique used to visualize nerve fibers, reticular fibers, and certain fungi in tissue specimens. It involves impregnating the tissue with a silver solution, which binds to the target structures, allowing them to be visualized under a microscope. This staining method is particularly useful for studying the morphology and distribution of these structures in various tissues.
