Detailed explanation-1: -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-2: -tuberculosis complex, produce a type of spore known as an endospore.

Detailed explanation-3: -tuberculosis is an aerobic, non–spore-forming, nonmotile bacillus with a high cell wall content of high-molecular-weight lipids.

Detailed explanation-4: -Mycobacteria are slender, non spore-forming, rod-shaped, aerobic, slow-growing, and free-living in soil and water. These bacteria have a generation time of about 20 h, thus isolation and identification may take up to 6 weeks (although a few species may grow in only 5–7 days).
