Tubercle bacilli may survive in unstained heat-fixed sputum smears and may be an infection risk to laboratory staff. We compared the effectiveness of 1% and 5% sodium hypochlorite, 5% phenol, 2% glutaraldehyde, and 3.7% formalin in killing Mycobacterium tuberculosis present in smears prepared from 51 sputum samples.

Bergey’s Manual initially divides the bacilli according to Gram stain reaction. Gram positive bacilli are further subdivided according to whether they form endospores, have filamentous growth or hyphae, and if they are acid-fast. Gram-negative bacilli are typically distinguished by size, shape, motility, and oxygen growth categories.

The morphology of strain Ph6 was determined by conventional methods. In the hydroponic experiments, ryegrass was used as the model plant because of its fast growth and well developed root system.

Known as “acid-fast bacilli” because of their lipid-rich cell walls. Once stained, the cells resist decolorization with acidified organic solvents and are therefore called “acid-fast”. Morphology: These are slender, beaded bacilli and nonsporing. Colonies are rough,

Trehalose 6,6′-dimycolate, called cord factor, is a glycolipid present in the cell wall of the mycobacteria that contributes to the virulence of M. tuberculosis and promotes growth as tight, rope-like aggregates of acid-fast bacilli (AFB) in which the long axes of the bacteria parallel the long axes of the cord.

If colony morphology resembles Mycobacterium tuberculosis (MTB) complex or no previous clinical history indicating nontuberculosis infection is available, a line probe assay to detect M. tuberculosis will be performed.

Ziehl and Neelsen independently proposed acid-fast stain in 1882-1883, which is commonly used today. Some types of bacteria resist decolourization by acid as well as alcohol both and hence stated as acid-fast organism. 1 In this process carbol fuschin is the primary stain. 3%HCl in 95% alcohol is decoloriser and methylene blue acts as counter stain.

Mycobacterium tuberculosis (MTB) is a pathogenic bacterial species in the genus Mycobacterium and the causative agent of most cases of tuberculosis. First discovered in 1882 by Robert Koch, M. tuberculosis has an unusual, waxy coating on the cell surface (primarily mycolic acid ), which makes the cells impervious to Gram staining; acid-fast techniques are used instead.
