The procedure for staining using modified Ziehl-Neelsen (ZN) typically involves the following steps: First, the bacterial smear is fixed onto a slide and then stained with a primary stain, usually carbol fuchsin, which penetrates the mycobacterial cell wall. The slide is then heated gently to facilitate dye uptake, followed by cooling and rinsing with water. Next, the slide is decolorized with an acid-alcohol solution to remove the stain from non-acid-fast organisms, and finally, it is counterstained with methylene blue or another contrasting dye to visualize the background and non-acid-fast cells. The result is that acid-fast bacteria appear red against a blue background.
What else can I help you with?
Is carbol fuchsin the same as safranin?
No. safranin is the classic stain used in gram staining. Concentrated Carbol Fushin is mainly used for the ZN staining procedure to stain organisms such as Vibrio cholerae and Cryptosporidium. Diluted Carbol Fushin can however be used as a replacement counterstain for Safranin in the gram stain.
What staining procedure makes use of pararosanaline?
The Schmorl's stain procedure makes use of pararosaniline as one of its staining components. It is a histological staining method used to highlight cellular structures in tissues.
Principle and procedure of histological staining of carbohydrates?
Carbohydrate demonstration methods. Demonstrates Staining mechanisms and technical comments.
Which staining procedure uses heat to drive the stain in?
The heat-based staining procedure is called heat fixation. In this process, heat is used to adhere the specimen to the slide, allowing it to withstand the subsequent staining and washing steps without washing away.
Why is it important to follow the gram staining procedure?
This is simply important in order to have accurate staining results. If this is not followed, the process of the staining will result to false positives or false negatives.
What is the difference between ZN stain and modified ZN stain?
in Zn we use 3% decolorizer, while in modified 1% h2so4 is used, modified is used for paracite like Cryptosporidium, cyclosporidium and bacterias like nocaddia and actinomyces. also in modified heating isn't done.
What is the best staining procedure to view spirochaetes?

What is procedure is done to corneal abrasions to appear bright green?
Fluorescein staining
What Article V established what procedure so the Constitution can be modified as necessary?
Article V (5) established the amendment procedure so the constitution could be modified as necessary.
What diagnostic procedure used to detect corneal abrasions is known?
Fluorescein staining is the diagnostic procedure used to detect corneal abrasions. In this procedure, a special dye is applied to the eye, which highlights any damaged areas on the surface of the cornea under a cobalt blue light.
What staining procedure will be used to observe bacteria in the sputum sample?
A Gram stain is commonly used to observe bacteria in a sputum sample. This staining procedure helps visualize the bacterial cell wall structure and arrangement, aiding in the identification of different bacterial species.
