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
it is not a type of disease but is a type of staining technique to stain some species of bacteria.
Tuberculosis and Leprosy
It is Gram- Negative so it is not acid- fast
Acid fast rods seen in sputum are diagnostic of tuberculosis.
The function of a counterstain in acid-fast stains is to dye the non acid-fast bacteria cells a different color than the acid-fast cells. With two different colors present on a slide, the contrast between the two types (acid-fast and non acid-fast) is more distinct. The more distinct view of cells will assist in observations of a slide.
The heat is the mordant for an acid-fast stain
NO, s. epidermidis does not show up positive in an acid fast stain. The acid fast stain is a differential stain that differentiates cells with mycolic acids in their cells walls with those who do not. cells with mycolic acid are therefore acid fast. s epidermidis does not contain this waxy substance in their cell wall so it doesnt fall into this category.
Mycobacterial, tuberculosis
Pulmonary tuberculosis is caused by acid fast bacilli infection of the lungs.
Saprophytic mycobacteria are acid fast and do not cause serious disease.
Not always. Saprophytic Mycobacteria are acid-fast positive and don't cause disease. The kinds of acid-fast organisms that do cause disease, like Mycobacterium tuberculosis, are more difficult to treat with antibiotics because of the large amounts of lipids in their cell walls so they do cause serious disease.
Acid-fast staining is used in determining tuberculosis. It can also track the progress of antibiotic therapy and determine how contagious a person is. Yay A&M microbiology lab!
No, endospores are not acid fast because they are not cells. Endospores will stain with the acid fast stain and look fuchsia but they are not positive for acid fast.
No. in comparison to M. smegmatis which is acid fast positive. e. coli will appear blue when tested with the Zeihl-Neelsen acid fast stain
Acid fast organism in sputum suggest that the patient is having the pulmonary tuberculosis. This is potentially treatable condition. When this organism is found in skin scrapping, it indicates that the person may have leprosy. This is mild disease of low virulence. In both the cases you have to take treatment for long period.
It is Gram- Negative so it is not acid- fast
Acid-fast bacteria stain pink. Non acid-fast bacteria stain green.
The decolorizing agent in the acid fast stain is acid alcohol. The decolorizing agent in the gram stain is ethanol.
Acid fast rods seen in sputum are diagnostic of tuberculosis.
