Helical Shape Bacteria Are Called
What is the name for rigid bacteria with a helical shape?
Accordingly, what are helical bacterial cells called? Spiral bacteria can be subclassified by the number of twists per cell, cell thickness, cell flexibility, and motility. The two types of spiral cells are spirillum and spirochete, with spirillum being rigid with external flagella, and spirochetes being flexible with internal flagella. More Information
Helicobacter pylori - Wikipedia
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, microaerophilic, spiral (helical) bacterium usually found in the stomach. Its helical shape (from which the genus name, helicobacter, derives) is thought to have evolved in order to penetrate the mucoid lining of the stomach and thereby establish infection.

Spirilla Bacteria - Definition, Examples, Shape, Diseases
Like members of the genus Oceanospirillum, Aquaspirillum species are rigid helical cells. As such, they are characterized by a helical or spiral shape. While this shape is common for the majority of species, researchers have identified a few species that either have a vibrioid or curved shape (A. fasciculus, on the other hand, are straight rods).

Morphology of Bacteria- Sizes, Shapes, Arrangements, Examples
Spirochetes are spiral bacteria having a helical shape. These are flexible and have an axial filament which helps in motility. These filaments are essential distinguishing character between spirochetes and other bacteria. These filaments run throughout the length of the bacteria and thus, help in twisting the motion of the bacteria. More Information
round shaped bacteria are called - Wildlife in Need
The smallest bacteria is Mycoplasma genitalium which is approximately 200 to 300 nm in size. The round shaped bacteria are called cocci, the rod shaped ones are called bacilli, spiral shaped ones are spirilla, and sometimes the same bacteria can have multiple forms, in which case they’re called pleomorphic. A. More Information

When a bacterial cell completes one or more complete turns and produces helical shape and stays rigid, then these bacteria are called spirilla. Like as spirochetes they lack endoflagella Example: Aquaspirillum, Campylobacter jejuni, Spirillum winogradskyi, Oceanospirillum. More Information
