The term bacillus has been applied in a general sense to all cylindrical or rodlike bacteria. The largest known Bacillus species, B.

Detailed explanation-2: -Bacillus species are rod-shaped, endospore-forming aerobic or facultatively anaerobic, Gram-positive bacteria; in some species cultures may turn Gram-negative with age. The many species of the genus exhibit a wide range of physiologic abilities that allow them to live in every natural environment.

Detailed explanation-3: -Prokaryotic cells are typically shaped as either spheres (called cocci), rods (called bacilli), or spirals.

Detailed explanation-4: -Bacillus is a genus of bacteria that are rod-shaped, aerobic and gram-positive.

Detailed explanation-5: -Examples of rod-shaped bacteria include Bacillus anthracis (B. anthracis), or anthrax. Spiral: These are known as spirilla (singular spirillus). If their coil is very tight they are known as spirochetes. Leptospirosis, Lyme disease, and syphilis are caused by bacteria of this shape.
