What are bacilli?

Bacilli are a type of bacteria characterized by their short, rod-shaped structure. This morphological feature is a key characteristic that distinguishes bacilli from other bacterial forms. For example, spiral-shaped bacteria are known as spirilla, while spherical bacteria are referred to as cocci. The rod shape of bacilli allows for a diverse range of adaptations and functions within different environments, making them significant in various biological and ecological contexts. Their shape influences not only their movement and growth patterns but also their interaction with host organisms and their role in diseases or benefits to human health. Understanding this structure is crucial in fields like microbiology and medicine, where bacteria can play a significant role in infections or even in beneficial processes like fermentation.
