Mycobacterium tuberculosis is an acid fast bacterium. It has a high concentration of mycolic acids in the plasma membrane which prevent its staining by typical Gram stain methods. It must be stained with a procedure containing an acid decolorizing step to best visualize it under the microscope (Ziehl Nielson or Kinyon Methods). It resists decolorization with the acid, which is where the term "Acid Fast" comes from....

What disease is an acid-fast bacilli smear used for diagnosis?
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.
M smegmatis acid fast?
Mycobacterium smegmatis is a fast-growing species of mycobacteria, but it is not acid-fast like the pathogenic mycobacteria such as Mycobacterium tuberculosis. Acid-fast staining is a characteristic feature of mycobacteria that have a waxy lipid layer in their cell wall, which makes them resistant to staining by conventional methods.
Is staphylococcus aureus acid fast?
No, Staphylococcus aureus is not acid-fast. Acid-fast bacteria, like Mycobacterium tuberculosis, retain the stain when treated with acid-alcohol. Staphylococcus aureus is a Gram-positive bacterium that retains the crystal violet stain in the Gram staining method.
IS 0.1 M strong acid a better conductor than 1 M weak acid?
Yes, a 0.1 M strong acid would likely be a better conductor than a 1 M weak acid because strong acids dissociate completely into ions in solution, making them better conductors of electricity compared to weak acids which only partially dissociate.
How do you convert m-nitrobenzoic acid into methyl m-nitrobenzoate?
m-Nitrobenzoic acid can be converted into methyl m-nitrobenzoate by reacting it with methanol and an acid catalyst such as sulfuric acid. The reaction is an esterification process that involves combining the m-nitrobenzoic acid with methanol to form the corresponding ester, methyl m-nitrobenzoate, and water as a by-product. This reaction is commonly carried out under reflux conditions to drive the reaction to completion.
Why is mycobacterium tuberculosis considered acid fast?
Saprophytic mycobacteria are acid fast and do not cause serious disease.
What is a acid fast disease?
Some diseases are leprosy ( M. leprae), tuberculosis (M. tuberculosis), and nocardiosis ( N. brasiliensis, N. asteroides). The acid fast stain is important in identifying bacteria in the genus Mycobacterium and Nocardia.M. tuberculosis

Could an acid fast organism be coccobacillus shaped?
Yes an Acid fast organism could be coccobacillus shaped, eg. Mycobacterium avium, M. gordonae, M. montefiorense, Rhodococcus and even brucella species ( in modified cold acid fast staining) etc.
Is a m and m an acid or a base?
A acid
What to do if you are getting sputum every morning?
See your medical practitioner. They will most likely provide you with a sterile specimen container to collect a sample. This sample will then be sent to the laboratory for microscopy, culture, and sensitivity testing (M/C/S). If tuberculosis (TB) is suspected then acid-fast bacilli (AFB) will also be added to the request form.
Can you get Tuberculosis?
yes. secondary tuberculosis which is more common in adult is actually the reactivation of the bacterial (M. Tuberculosis) which remain dormant in the lung after the first infection that can go back years ago.
What has the author Arvind M Dhople written?
Arvind M. Dhople has written: 'Rapid susceptibility testing of mycobacterium avium complex and mycobacterium tuberculosis isolated from AIDS patients' -- subject(s): Mycobacteria, Tuberculosis
How does one get a tuberculosis?
yes. secondary tuberculosis which is more common in adult is actually the reactivation of the bacterial (M. Tuberculosis) which remain dormant in the lung after the first infection that can go back years ago.
What are the characteristic structures of bacillus M. tuberculosis and what they cause?
Mycobacterium tuberculosis, the bacterium causing tuberculosis, has a unique cell wall structure characterized by a thick layer of mycolic acids and peptidoglycan, which contributes to its acid-fastness. This structure protects the bacterium from desiccation and immune responses, allowing it to survive in harsh environments. Additionally, the presence of complex lipids in its cell wall can trigger strong inflammatory responses, leading to tissue damage in the host and the formation of granulomas, which are hallmark features of tuberculosis infections.
