What staining procedure will be used to observe bacteria in the sputum sample?
acid fast staining or Ziel Neelson staining for observing Mycobacteria tuberculosis or Koch bacilli from sputum sample.
What are the large blue-stained areas on the sputum slide?
they are white blood cells, or neutrophils. all non acid fast cells and tissue cells will turn blue.
Is Proteus Vulgaris acid-fast?
It is Gram- Negative so it is not acid- fast
Function of the counterstain in acid-fast?
The function of a counterstain in acid-fast stains is to dye the non acid-fast bacteria cells a different color than the acid-fast cells. With two different colors present on a slide, the contrast between the two types (acid-fast and non acid-fast) is more distinct. The more distinct view of cells will assist in observations of a slide.
Is mordant used in acid fast stain?
The heat is the mordant for an acid-fast stain
What is sputum ASB test?
It is actually a sputum AFB test (acid-fast bacilli).

acid fast staining or Ziel Neelson staining for observing Mycobacteria tuberculosis or Koch bacilli from sputum sample.
What are the large blue-stained areas on the sputum slide?
they are white blood cells, or neutrophils. all non acid fast cells and tissue cells will turn blue.
What is sputum AFB test?
Acid fast bacilli test. Most frequently referenced in testing for tuberculosis.
Does presence of acid fast organisms in a clinical specimen always suggest serious clinical disease?
Acid fast organism in sputum suggest that the patient is having the pulmonary tuberculosis. This is potentially treatable condition. When this organism is found in skin scrapping, it indicates that the person may have leprosy. This is mild disease of low virulence. In both the cases you have to take treatment for long period.
Are endospores acid fast?
No, endospores are not acid fast because they are not cells. Endospores will stain with the acid fast stain and look fuchsia but they are not positive for acid fast.
Do acid-fast organisms always suggest serious disease?
Not always. Saprophytic Mycobacteria are acid-fast positive and don't cause disease. The kinds of acid-fast organisms that do cause disease, like Mycobacterium tuberculosis, are more difficult to treat with antibiotics because of the large amounts of lipids in their cell walls so they do cause serious disease.
Is staphylococcus aureus acid fast?
No. in comparison to M. smegmatis which is acid fast positive. e. coli will appear blue when tested with the Zeihl-Neelsen acid fast stain
Is Proteus Vulgaris acid-fast?
It is Gram- Negative so it is not acid- fast
What color is Brilliant green K in Acid fast cell?
Acid-fast bacteria stain pink. Non acid-fast bacteria stain green.
What is the decolorizing agent in the acid fast stain?
The decolorizing agent in the acid fast stain is acid alcohol. The decolorizing agent in the gram stain is ethanol.
Is Vibrio natriegens acid-fast?
Vibrio natriegens is not acid fast, it is Gram negative.
