Web. Very few structures are acid-fast; this makes staining for acid-fastness particularly useful in diagnosis. If you look around you, the surfaces in your life are probably pretty clean. For color blind people (or in backgrounds where detecting red bacteria is difficult). Learn how these bacteria are identified and about the unique structure of their cell walls that classify them as such. Pages in category "Acid-fast bacilli" The following 113 pages are in this category, out of 113 total. Some bacteria may also be partially acid-fast, such as Nocardia. Medical. Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name acid-fast. The following are notable examples of structures which are acid-fast or modified acid-fast: Tuberculosis, commonly known as TB, is a serious bacterial infection that mainly affects the lungs. Diseases caused by acid-fast organisms, Mycobacterium, et al.TB is due to acid-fast bacillus (?)

Acid-fastness is a physical property of certain bacterial and eukaryotic cells, as well as some sub-cellular structures, specifically their resistance to decolorization by acids during laboratory staining procedures. (AFB) are mycobacterium, of which the most famous is m. Tuberculosis. An unseen world exists that is composed of bacteria, or single-celled organisms that lack any membrane-bound compartments called organelles. Acid-fast Mycobacteria can also be visualized by fluorescence microscopy using specific fluorescent dyes (auramine-rhodamine stain, for example). 2 Gram-positive acid-fast bacteria Acid-fast bacteria (e.g. Acid- Fast Bacilli (AFB) smear and culture are two separate tests always performed together at the MSPHL, Tuberculosis (TB) Unit. The most common staining technique used to identify acid-fast bacteria is the Ziehl-Neelsen stain, in which the acid-fast species are stained bright red and stand out clearly against a blue background.

Get instant explanation for any acronym or abbreviation that hits you anywhere on the web! Another method is the Kinyoun method, in which the bacteria are stained bright red and stand out clearly against a green background. ). Most relevant lists of abbreviations for AFB (Acid-fast Bacilli) [1][2] Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name acid-fast.[2]. The differentiation of the different human and animal pathogenic acid-fast bacilli from the avirulent saprophytes and other harmless mycobacteria presents great difficulties, but methods are becoming available which usually make this possible.
