What term describes bacteria that are spiral shaped?

The term that describes bacteria with a spiral shape is seamlessly captured by "Vibrio, spirillum, spirochete." Each of these classifications pertains to specific types of spiral-shaped bacteria.

Vibrio refers to comma-shaped bacteria, characterized by their curved rod form. Spirillum is more commonly associated with longer, rigid spiral forms. Spirochetes, however, are distinguished by their long, thin, flexible spirals, enabling unique motility in a corkscrew motion which allows them to navigate through viscous environments. This variety in shape and structure underlines the diversity of spiral-shaped bacteria, distinguishing them from other forms such as cocci and bacilli.

In contrast, the other terms mentioned do not encompass the spiral shape. Cocci refers to spherical bacteria, while bacilli are rod-shaped. Filamentous describes a form that is more elongated and thread-like rather than spiral, providing clarity that the chosen answer comprehensively covers the range of spiral-shaped bacteria.
