Acid-fast bacillus (AFB) is a type of bacteria that causes tuberculosis and other types of mycobacterial infections, such as leprosy (Hansen's disease). AFB tests are usually ordered for people with symptoms of active tuberculosis, commonly known as TB.

2023年8月7日 · Acid-fast bacteria, also known as acid-fast bacilli or simply AFB, are a group of bacteria sharing the characteristic of acid fastness. Acid fastness is a physical property that gives a bacterium the ability to resist decolorization by acids during staining procedures.

The acid-fastness of Mycobacteria is due to the high mycolic acid content of their cell walls, which is responsible for the staining pattern of poor absorption followed by high retention. Some bacteria may also be partially acid-fast, such as Nocardia.

2023年5月28日 · What Is an AFB Stain? Your doctor may use an acid-fast bacteria (AFB) stain test to see if you have a lung disease like tuberculosis (TB). In addition to showing tuberculosis, an AFB stain...

2021年11月9日 · To help diagnose tuberculosis (TB) and infections caused by other Mycobacterium species, which are known as acid-fast bacilli (AFB), in people at risk of developing mycobacterial infections; to monitor the effectiveness of treatment. When To Get Tested?

An acid-fast bacteria (AFB) culture is done to find out if you have tuberculosis (TB) or another mycobacterial infection. Besides TB, the other main mycobacterial infections are leprosy and a TB-like disease that affects people with HIV/AIDS.

The Acid-Fast Bacilli (AFB) Test is a crucial diagnostic tool for detecting mycobacterial infections, primarily tuberculosis (TB) and leprosy. It identifies acid-fast bacteria, which have a unique cell wall that resists standard staining techniques.

Acid-fast bacillus (AFB) is a type of bacteria that causes tuberculosis and certain other infections . Tuberculosis, commonly known as TB, is a serious bacterial infection that mainly affects the lungs. It can also affect other parts of the body, including the brain, spine, and kidneys.
