What is anthrax gram stain?
The Gram stain for anthrax shows large, Gram-positive bacilli that appear as long chains of cells. Anthrax bacteria stain blue or purple because of their thick peptidoglycan cell wall, which retains the crystal violet dye used in the Gram staining procedure.
What is the importance of hematoxylin stain in histology?
Hematoxylin stain is used in histology to selectively stain cell nuclei blue, allowing for better visualization of tissue morphology and structures. It serves as a contrast stain in combination with eosin stain, highlighting cellular and tissue features for microscopic analysis and diagnosis.
What is a bacillus that stains red with gram stain called a. gpc b. GNC c. gpr d. gnr?
A
What does a simple stain of bacillus megaterium look like under a microscope?
Simple or gram? Simple uses methylene blue, gram uses crystal violet
How would you describe the morphology and arrangement of the cells in your capsule stain preparations?
Bacterial cells typically have one of three shapes: spherical (coccus), oblong (bacillus), or curved (spirillum of vibrio). Depending on the plane of binary fission, cells form chains, clusters with various geometry, or single cells.
What are the acid-fast stain results for Bacillus subtilis?
Bacillus subtilis is a Gram-positive bacterium and does not typically show acid-fast staining results. This means that it does not retain the stain when subjected to the acid-fast staining procedure commonly used to detect mycobacteria.
What is anthrax gram stain?
The Gram stain for anthrax shows large, Gram-positive bacilli that appear as long chains of cells. Anthrax bacteria stain blue or purple because of their thick peptidoglycan cell wall, which retains the crystal violet dye used in the Gram staining procedure.

What is the value of simple stain?
A simple stain like iodine can make cell parts show up that would otherwise be nearly invisible since they are colorless.A simple stain like iodine will reveal a cell's morphology.
What color is simple staining on a bacillus and coccus using methylene blue stain?
Methylene blue stains everything blue.
What is the bacteria mophology for bacillus subtilis by simple stain?
B. subtilis is indeed a Gram positive rod.However, there is confusion as to whether it is an obligate aerobe or a facultative anaerobe. Although classed as an obligate aerobe, it has been shown to grow under strict anaerobic conditions.
What is a bacillus that stains red with gram stain called a. gpc b. GNC c. gpr d. gnr?
A
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.
What is the difference between Wright stain and Giemsa stain?
The Wright stain is a combination of eosin and methylene blue dyes, while Giemsa stain is a mixture of eosin, methylene blue, and azure dyes. Giemsa stain is commonly used for staining blood smears to visualize parasites and bacteria, while Wright stain is used more for general cell morphology in blood and bone marrow specimens.
Is B subtilis a gram positive or gram negative bacterium?
gram positive Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this bacterium is gram (+).
Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin Through the microscope the green structures are?
Bacillus cells stained with malachite green and safranin will appear red under the microscope due to the counterstaining with safranin. Malachite green primarily stains the spores of Bacillus while safranin stains the rest of the cell, resulting in red-stained vegetative cells and green-stained spores.
What does a simple stain of bacillus megaterium look like under a microscope?
Simple or gram? Simple uses methylene blue, gram uses crystal violet
