Corynebacterineae is a suborder of the Actinomycetales and includes most of the acid-fast bacteria.

Acid-fast bacteria retains Carbol Fuchsin so they appear red.

Mycobacterium phlei is an acid-fast bacteria of the genus Mycobacterium.

Mycobacteria are sometimes referred to as "acid-fast bacteria," a term referencing their response to a laboratory staining technique.

It is an intracellular, pleomorphic, acid-fast bacterium.

Acid-fast bacteria can also be visualized by fluorescence microscopy using specific fluorescent dyes (auramine-rhodamine stain, for example).

Rhamnose is also a component of the outer cell membrane of acid-fast bacteria in the Mycobacterium genus, which includes the organism that causes tuberculosis.

Giant multinucleated cells are seen in the early stages of active infection with the acid-fast bacterium Mycobacterium tuberculosis, the causative agent of the disease tuberculosis.

When they are destained with acid-alcohol, only non-acid-fast bateria get destained since they don't have a thick, waxy lipid layer like acid-fast bacteria.

With pathologist Friedrich Neelsen (1854-1898), he developed the Ziehl-Neelsen stain, also known as the acid-fast stain, which is used to identify acid-fast bacteria.

(+)-Totarol exhibits antimicrobial properties in numerous species including gram-positive bacteria, acid-fast bacteria, nematodes, parasitic protozoans, crustaceous foulers (Table 1).

An intracellular, acid-fast bacterium, M. leprae is aerobic and rod-shaped, and is surrounded by the waxy cell membrane coating characteristic of Mycobacterium species.

The most common staining technique used to identify acid-fast bacteria is the Ziehl-Neelsen stain, in which the acid fast bacilli are stained bright red and stand out clearly against a blue background.

Recently (+)-totarol was also hypothesized to inhibit gram-positive and acid-fast bacteria via inhibition of FtsZ protein, which forms the Z-ring, a polymer necessary for efficient bacterial cell cytokinesis.

Auramine O can be used to stain acid-fast bacteria (e.g. Mycobacterium, where it binds to the mycolic acid in its cell wall) in a way similar to Ziehl-Neelsen stain.

Together with microbiologist Franz Ziehl, Neelsen developed a method for the staining of acid-fast bacteria, used to this day in the diagnosis of Tuberculosis and to detect the presence of other mycobacteria.

Diagnosis is usually performed by needle aspiration biopsy or excisional biopsy of the mass and the histological demonstration of stainable acid-fast bacteria in the case of infection by M. tuberculosis (Ziehl-Neelsen stain), or the culture of NTM using specific growth and staining techniques.
