Bacilli bacteria are characterized by which shape?

Bacilli bacteria are characterized by a rod shape, which distinguishes them from other bacterial shapes. This rod-like structure allows bacilli to have a specific form that is often associated with their growth and reproduction methods. The term "bacillus" itself derives from the Latin word for "rod," which reflects their elongated cylindrical morphology.

This rod shape provides certain advantages for bacilli, such as facilitating movement and the ability to form chains or clusters depending on their division patterns. Understanding this characteristic is essential in microbiology, as the shape of bacteria can influence their identification, classification, and the type of infections they may cause.
