Detailed explanation-1: -The bacterium has neither cilia or flagella, and is therefore non-motile. Its hydrophobic cell wall contains a high concentration of lipids which repels water. Metabolically, M. tuberculosis is obligate aerobic; it requires oxygen to undergo cellular respiration.

Detailed explanation-2: -Mycobacterium tuberculosis is a nonmotile, non-spore-forming, obligate aerobe, acid-fast bacillus that often appears beaded or unstained using Gram stain. Like all mycobacteria, it is distinguished by its ability to form stable mycolate complexes with arylmethane dyes (carbolfuchsin, auramine, and rhodamine).

Detailed explanation-3: -M. tuberculosis is a small, rod-shaped, strictly aerobic, acid-fast bacillus a. Acid-fast bacilli are bacilli, which once stained, resist discoloration by acid and alcohol. . Like other mycobacteria, it is slow growing, resulting in more gradual development of disease when compared with other bacterial infections.

Detailed explanation-4: -TB bacteria spread through the air from one person to another. When a person with TB disease of the lungs or throat coughs, speaks, or sings, TB bacteria can get into the air. People nearby may breathe in these bacteria and become infected.
