What does the simple stain tell us about the bacteria?
The result of simple staining of microorganisms is that they can be identified and studied under a microscope.
What is anthrax gram stain?
A Bacillus (Gram +) produces an endospore. It is called Bacillus. anthracis and causes the disease anthrax.
What are the gram reactions of clostridium?
What are the gram reactions of clostridium and bacillus
What color is coccus under a microscope?
All bacteria, including cocci, are colorless under the microscope unless you use a light filter or a stain. If you use a light filter or a stain then the color depends on which wavelength the filter is for or which type of stain you are using.
What is a bacillus that stains red with gram stain called a. gpc b. GNC c. gpr d. gnr?
A
What color is simple staining on a bacillus and coccus using methylene blue stain?
Methylene blue stains everything blue.
What does the simple stain tell us about the bacteria?

What is anthrax gram stain?
A Bacillus (Gram +) produces an endospore. It is called Bacillus. anthracis and causes the disease anthrax.
Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin Through the microscope the green structures are?
The malachite green penetrates the endospores, the counterstain of safranin will stain the vegetative cells. Endospores - greenish-blue Vegetative Cells - Red/Pink
What strain of plague do fleas carry?
Fleas carry the bacterium Yersinia pestis, formerly known as Pasteurella pestis. The plague bacillus can be stained with Giemsa stain and typically looks like a safety pin under the microscope.
Why is the gram stain technique more valuable than the simple stain technique in the diagnostic laboratory Under what circumstances might the simple stain be preferable to the gram stain technique?
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.
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 are the gram reactions of clostridium?
What are the gram reactions of clostridium and bacillus
Carbolfuchsin can be used as a simple stain and as a negative stain as a simple stain the pH is?
8
What is the function of a stain in microscope work?
As the cells are transparent, the components cannot be seen clearly through a microscope. We stain the cell so that we can see the components of the cell clearly through a microscope.
What structure in the cheek cells was stained the darkest?
When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.
Why is a stain called a stain?
It's simple, because it's a stain.
