In both cases the helical shape can be destroyed by fairly simple gene knockouts, and in both bacteria the loss of the helical shape resulted in a decrease in virulence and the ability of the... More Information
The secrets of the helical shape of H. pylori
The helical shape of Helicobacter pylori (H. pylori) bacteria is essential for its pathogenicity. The Salama lab (Human Biology Division), whose research focuses on these bacteria, demonstrated in the past that mutant H. pylori that lost their helical shape were less efficient at infiltrating the stomach mucosa and thus less pathogenic.

Helical and rod-shaped bacteria swim in helical ...
As their name suggests, the helical shape of these bacteria is one of their most salient features and is purported to be an important factor in the ability of the bacterium to traverse the... More Information
Spiral bacteria - Wikipedia
From Wikipedia, the free encyclopedia Spiral bacteria, bacteria of spiral (helical) shape, form the third major morphological category of prokaryotes along with the rod-shaped bacilli and round cocci. Spiral bacteria can be subclassified by the number of twists per cell, cell thickness, cell flexibility, and motility. More Information

Organisms with more complex shapes, including curved, filamentous, and helical bacteria, were all abundantly represented. Missing from the collection, however, were bacteria with a coccoid (spherical) morphology, both Gram-positive and Gram-negative. More Information
How Helicobacter stays helical - Fred Hutch
One of H. pylori ’s defining characteristics is right there in its name: its helical shape. Its shape doesn’t just help scientists spot H. pylori under the microscope; the bug’s corkscrew form is critical to its ability to escape stomach acid and anchor in for the long haul by swimming through the stomach’s mucus lining.

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
With regards to shape, Spirillum bacteria also have a helical shape (spiral) with one to about 5 complete helical turns. However, there have been instances where microscopic studies have revealed an incomplete helical turn. Locomotion is made possible by the presence of bipolar flagella that are crescent-shaped.

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
3 Common Bacteria Shapes - ThoughtCo
Bacteria are single-celled, prokaryotic organisms that come in different shapes. They are microscopic in size and lack membrane-bound organelles as do eukaryotic cells, such as animal cells and plant cells.Bacteria are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents, hot springs, and in your digestive tract.
