The ziehl stain smear shows presence of pus cells along with long slender beaded acid fast bacill.
Tuberculosis is characterized by acid-fast bacilli infection of the lungs. The bacilli are resistant to decolorization by acid-alcohol during staining, hence the term "acid-fast." Symtoms of TB include coughing, chest pain, weight loss, and fatigue.
An acid-fast bacilli smear is commonly used for diagnosing tuberculosis, which is caused by the bacterium Mycobacterium tuberculosis. The test helps to identify the presence of acid-fast bacteria in patient samples, providing an initial indication of a possible tuberculosis infection.
Because special staining techniques involving acids are required to view these bacteria under the microscope, they are referred to as acid-fast bacilli (AFB).
Acid-fast bacteria, primarily Mycobacterium species, typically exhibit rod-shaped (bacilli) structures. They often appear in arrangements such as single rods, pairs, or in small clusters. The characteristic waxy cell wall of these bacteria makes them resistant to decolorization by acid-alcohol, which is the basis for the acid-fast staining technique. This unique structure contributes to their distinctive morphology and slow growth rates.
Mycobacterium species, such as Mycobacterium tuberculosis, are the bacteria commonly used in acid-fast staining due to their high lipid content in the cell wall, which makes them resistant to destaining with acid-alcohol solutions. This characteristic allows them to retain the primary stain, carbol fuchsin, and appear "acid-fast" red under the microscope.

Some examples of acid-fast bacilli include Mycobacterium tuberculosis, Mycobacterium leprae, and Nocardia species.

Mycobacterial, tuberculosis
Because special staining techniques involving acids are required to view these bacteria under the microscope, they are referred to as acid-fast bacilli (AFB).
Acid-fast bacilli are a group of bacteria that resist decolorization by acids during laboratory staining procedures. These bacilli include species such as Mycobacterium tuberculosis, which causes tuberculosis. Acid-fast staining helps in their identification due to their unique cell wall composition.
It is actually a sputum AFB test (acid-fast bacilli).
"No acid fast bacilli seen" means that no bacteria with a cell wall that is resistant to acid staining, such as Mycobacterium tuberculosis, were observed in the specimen tested. This result is important in ruling out certain bacterial infections, particularly tuberculosis.
Acid fast bacilli test. Most frequently referenced in testing for tuberculosis.
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.
Mycobacterium avium complex (MAC) bacteria are weakly acid-fast, meaning they retain some of the carbol fuchsin stain when decolorized with acid-alcohol during acid-fast staining. This makes them appear weakly positive in acid-fast staining techniques.
a fluorescent dye used to stain the cell walls of fungi and bacteria. The organisms then fluoresce when exposed to UV light rays. It is commonly used to visualize acid-fast bacilli (mycobacteria) in specimens. An example is acridine orange staincomsats Pharmacy (sandboy_2008@yahoo.com)
