Is Proteus Vulgaris acid-fast?
It is Gram- Negative so it is not acid- fast
Cite the purpose of following reagents in a differential staining procedure?
To distinguish between acid fast positive and acid fast negative bacteria. Acid fast positive bacteria will stain red to pink color and acid fast negative bacteria will stain blue. Acid fast positive bacteria have mycolic acid in their cell wall, which will stain with carbol fuchsin and not decolorize with acid alcohol. Acid fast negative bacteria do not have mycolic acid in their cell wall, and become decolorize with the acid alcohol. Counterstain of methylene blue needs to be done in order to see the acid fast negative.
Is the mycobacterium smegmatis positive to acid-fast?
NO, s. epidermidis does not show up positive in an acid fast stain. The acid fast stain is a differential stain that differentiates cells with mycolic acids in their cells walls with those who do not. cells with mycolic acid are therefore acid fast. s epidermidis does not contain this waxy substance in their cell wall so it doesnt fall into this category.
Acid fast sputum?
Acid fast rods seen in sputum are diagnostic of tuberculosis.
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 Proteus Vulgaris acid-fast?
It is Gram- Negative so it is not acid- fast
Is Vibrio natriegens acid-fast?
Vibrio natriegens is not acid fast, it is Gram negative.
Is serratia marcescens acid-fast?
Serratia marcesens is an acid fast negative bacillus. It appears blue under the microscope.
Are acid fast negative cell stained by carbolfuchhsin?
yes
Are acid fast bacteria gram positive or negative?
it is positive
Does carbolfuchsin stain acid fast negative cells?
Yes, carbolfuchsin can stain acid-fast negative cells. This red dye can easily get into their thin cell wall lipids due to its solubility.
Why is acid fast staining of intestinal sample of limited value?
E.Coll is definitely acid fast negative,due to its ability to dye with methylene blue.
Acid fast staining of E. coli?
E. Coli is definitely acid fast negative, due to it's ability to dye with methylene blue. It has no outer waxy exterior..

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.
Why is E. coli acid fast negative?
Most acid-fast microorganisms belong to the genus Mycobacterium because organisms of this species have a unique property where they have a lipid rich mycolic acid exterior that prevents ordinary dyes from penetrating.When decolorized and counterstained, they maintain the red of the carbolfushin, thus they are acid fast.E. coli is affected by the decolorization by the acid achohol and counterstain by the methylene blue dye because they lack the mycolic acid layer, thus they are non-acid fast.
