Tuberculosis and leprosy are two diseases caused by acid fast bacteria.
diseases in the Mycobacterium genus Tuberculosis, leprosy etc.
Tuberculosis is caused by an acid-fast bacteria called Mycobacterium tuberculosis.
The bacteria that causes tuberculosis is mycobacterium tuberculosis an acid fast bacteria
Acid-fast bacteria stain pink. Non acid-fast bacteria stain green.
Enterobacter aerogenes is a non-acid fast bacteria. Bacteria only in the Mycobacteria and Nocardia genus are acid fast.
Acid-fast and Gram stain are two different types of staining technique. Bacteria that stain with acid-fast techniques are called "acid fast bacteria." Bacteria that don't stain with acid-fast techniques are called "not acid fast." At the same time, bacteria can be "Gram-positive" or "Gram-negative." For example, Nocardia is a bacterium that is acid-fast and Gram-positive. Usually the reason people care about these designations is in order to figure out what species a bacteria is. The issue usually arises in the context of a patient's sample that has grown bacteria. At first the doctors won't be sure which bacteria it is. They'll have guesses based on how the patient presented, but they won't know, and they want to know because that will help them pick the best treatment. A first step toward "speciating" the bacteria is to do a Gram stain on it. This is because for historical reasons determining whether a bacteria is Gram-positive or Gram-negative goes a long way toward speciating it. Acid-fast staining is less common, and is used mostly for diagnosing tuberculosis (caused by Mycobacteria, which are acid-fast bacteria). There are details about the cell walls that determine whether an organism will stain with Gram stain (thick walls without mycolic acids) or acid-fast, but hopefully this answers your question.
By this technique, we can diffentiate the acid fast and non acid- fast bacteria. The non acid-fast bacteria are M.tuberculosis and N.asteriodes. They are the causative agents for tuberculosis and nocardiosis respectively. The acid fast staining or the Ziel- Nielsen's staining is the only procedure to find out the above mentioned pathogens.
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
no bacteria seen
yes
it is positive
Mycobacterium is am example for acid fast bacteria. These bacterias have large amounts of mycolic acids in their cell wall which are impermeable to any other staining technique.
