Do acid-fast bacteria stain gram-negative when subjected to the gram stain?
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.

Gram stain
What are the differences between acid-fast stain and Gram stain in terms of their staining techniques and applications in microbiology?
The acid-fast stain and Gram stain are two different staining techniques used in microbiology. The acid-fast stain is used to detect bacteria that have a waxy cell wall, such as Mycobacterium tuberculosis, while the Gram stain is used to differentiate bacteria based on their cell wall composition (Gram-positive or Gram-negative). The acid-fast stain involves using a special dye called carbol fuchsin and heat to penetrate the waxy cell wall, while the Gram stain uses crystal violet, iodine, alcohol, and safranin to differentiate bacteria based on their ability to retain the crystal violet dye. The acid-fast stain is commonly used to diagnose tuberculosis and leprosy, while the Gram stain is used to identify and classify bacteria in clinical and research settings.
What is the counter or secondary stain used in the Gram stain procedure?
The counter or secondary stain used in the Gram stain procedure is safranin.
Does yogurt stain gram positive or gram negative?
Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.
Can a gram stain detect chlamydia?
A gram stain cannot detect chlamydia. A gram stain in men that finds gram negative diplococci is considered diagnostic for gonorrhea, but it can't be used in females, and it can't prove chlamydia. A gram stain in men can be used to rule out gonorrhea and possibly diagnose "non-gonococcal urethritis" if a male has symptoms. However, although it may seem that NGU is synonymous with chlamydia, there are other possible causes.
Why to gram stain bacteria?
gram staining is a biochemical method of identifying bacteria in a more specific way.Thus it is important to differentiate gram positive and gram negative bacteria.
What type of organism would you look for in a Gram stain of the blood or cerebrospinal fluid in a menin gococcal case?
In a Gram stain of blood or cerebrospinal fluid in a meningococcal case, you would look for Gram-negative diplococci, which are indicative of Neisseria meningitidis. These bacteria are the causative agent of meningococcal disease. Their appearance in the Gram stain can help diagnose the infection.
Do acid-fast bacteria stain gram-negative when subjected to the gram stain?
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.

Can a Gram stain a prion?
Protists are often stained using a silver stain, not a Gram stain.
What is the gram stain of H5N1?
The Gram stain is used for bacteria and not for viruses.
What is the gram stain of enterobacter cloacae?
Enterobacter cloacae is a Gram-negative bacterium. It will stain pink or red in a Gram stain procedure.

What is the Gram stain for measles?
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
What is the counter or secondary stain used in the Gram stain procedure?
The counter or secondary stain used in the Gram stain procedure is safranin.
