What shape does the bacteria spirillum have?

Spirillum bacteria are characterized by their distinctive shape, which resembles a corkscrew or spiral. This shape is crucial to their classification within the bacterial kingdom, particularly among the helical or spiral-shaped groups. The corkscrew form allows these bacteria to exhibit a form of motility that can be highly effective in navigating through viscous environments, such as the liquid found in some hosts.

In recognizing the accuracy of this classification, it’s essential to note that other bacterial shapes—such as rod-shaped bacilli, spherical cocci, and comma-shaped vibrio—represent different categories and morphologies. Each bacterial shape not only defines their physical characteristics but also often correlates with their specific ecological roles and adaptation strategies.
