Spirochetes have a spiral shape, a flexible cell wall, and motility mechanisms based on structures called axial filaments. Each axial filament is composed of fibrils extending toward each other between two layers of the cell wall.
Spirochetes are very slender and difficult to see under the light microscope. They are cultivated with great difficulty (some cannot be cultivated), and their classification is based on their morphology and pathogenicity. Certain species inhabit water environments, while others are parasites of arthropods (such as ticks and lice) as well as warmblooded animals. Spirochetes include Borrelia burgdorferi, the agent of Lyme disease, Treponema pallidum, the cause of syphilis, and Leptospira interrogans, the agent of leptospirosis.
Spirilla have a spiral shape, a rigid cell wall, and motility mechanisms based on polar flagella. The genera Spirillum, Aquaspirillum, and Azospirillum are widely dispersed among and readily isolated from numerous environments. These organisms are aerobic bacteria wound like helices.
Spirilla are rigid, helical-shaped bacteria with flagella that move in a corkscrew motion, while spirochetes are flexible, helical-shaped bacteria that move by axial filaments called endoflagella encased within the periplasmic space. Spirilla are typically larger and have a more pronounced spiral shape compared to spirochetes.

Is the rigid helix found in spirochetes or in spirilla?
The rigid helix structure is found in spirochetes, which are spiral-shaped bacteria characterized by their flexible, corkscrew-like shape that allows them to move in a corkscrew motion. Spirilla, on the other hand, are spiral-shaped bacteria with a more rigid structure that do not exhibit the same flexible helical shape as spirochetes.
How are spirochetes and spirillum different?
Spirochetes are a type of bacteria characterized by a unique cork-screw shape and the ability to move by axial filaments, while spirillum are spiral-shaped bacteria that do not have the same corkscrew structure and mode of movement as spirochetes.
When bacteria are spiral shaped they are called?
spirillum
What type of bacteria contains endoflagella?
spirochetes
Is spirochetes a bacteria-like protist?
Spirochetes are a type of bacteria, not a protist. They are characterized by their spiral-shaped morphology and are known to cause diseases such as Lyme disease and syphilis.
What kingdom does a spirillum belong?
A spirillum belongs to the kingdom Bacteria. It is a type of bacteria that is characterized by its spiral shape.
Is the rigid helix found in spirochetes or in spirilla?
The rigid helix structure is found in spirochetes, which are spiral-shaped bacteria characterized by their flexible, corkscrew-like shape that allows them to move in a corkscrew motion. Spirilla, on the other hand, are spiral-shaped bacteria with a more rigid structure that do not exhibit the same flexible helical shape as spirochetes.

Spirochetes are a type of bacteria characterized by a unique cork-screw shape and the ability to move by axial filaments, while spirillum are spiral-shaped bacteria that do not have the same corkscrew structure and mode of movement as spirochetes.
What is the scientific name for spirillum?
Spirillum is the name of two species of spiral shaped, Gram-negative bacteria in the family Spirillaceae. The bacteria in the family are two species, Spirillum volutans and Spirillum winogradskyi. Spirillum have been found to be the cause of rat-bite fever and Lyme disease.
Which bacterial form can be curved like a spiral thick and rigid or thin and flexible?
The bacterial form that can be curved like a spiral can be either thick and rigid, known as spirilla, or thin and flexible, known as spirochetes. Both forms are capable of moving by rotating their bodies.
When bacteria are spiral shaped they are called?
spirillum
Is spirilla a shape of viruses?
No, Spirillum is a bacteria and not a virus. It basically twists like a spiral and there are 2 different species, Spirillum volutans and Spirillum winogradskyi.
What is capable of movement?
spirochetes
What kingdom is spirochetes in?
Eubacteria .
What is the common name for spirillum volutans ehrenberg?
The common name for Spirillum volutans Ehrenberg is "spirillum bacteria." These bacteria are spiral-shaped and often found in freshwater environments. They are known for their corkscrew-like swimming motion.
Is spirochetes in domain archaea?
Yes it is
Bacteria capable of movement?
spirochetes
