Is acid fast bacteria gram positive or negative?
Acid-fast bacteria are gram-positive.
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
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.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
Is acid fast bacteria gram positive or negative?
Acid-fast bacteria are gram-positive.
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
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.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
Is serratia marcescens acid-fast?
No, Serratia marcescens is a Gram-negative bacterium and is not acid-fast. Acid-fast staining technique is used to detect organisms like Mycobacterium tuberculosis, which have a waxy lipid layer in their cell wall that resists staining by conventional methods.
Are acid fast negative cell stained by carbolfuchhsin?
yes
Is Proteus Vulgaris acid-fast?
No, Proteus vulgaris is not acid-fast. Acid-fast bacteria retain the primary stain, carbol fuchsin, despite exposure to acid-alcohol decolorizer, while non-acid-fast bacteria do not retain the stain. Proteus vulgaris is a non-acid-fast bacterium.
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.
Is Vibrio natriegens acid-fast?
No, Vibrio natriegens is not acid-fast. Acid-fast bacteria have a waxy lipid layer in their cell wall that makes them resistant to acid decolorization during staining with acid-fast stains like Ziehl-Neelsen stain. Vibrio natriegens does not possess this characteristic lipid layer, so it is not acid-fast.
Is shigella dysentery acid fast positive?
No, Shigella dysentery is not acid-fast positive. Shigella is a genus of bacteria that are Gram-negative and do not retain the stain used in acid-fast bacilli (AFB) staining. Acid-fast positivity is characteristic of mycobacteria, such as Mycobacterium tuberculosis, not Shigella. Therefore, Shigella dysentery would not be identified as acid-fast in laboratory tests.
