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.
Spirilla, Vibrio, Cocci and Baccili
spirilla (spiral) bacilla (rod) and cocci (spherical) :) happy i could answer this one!
Prokaryotes can be rod shaped (bacilli), sphere shaped (cocci), or a spiral shape (spirilla)
Treponema pallidum. The bacteria causing syphilis. Borellia and Leptospira are other examples.
A spiral-shaped bacteria cell is called a spirillum. This type of bacteria is elongated and helical in shape, allowing it to move in a corkscrew-like manner. Spirilla are known for their unique spiral structure and are found in various environments.
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.
Coccus or cocci: round - spherical Bacillus or Bacilli: Rod Spirillum or Spirilla: rigid, wavy shape Pleomorphism: condition of varying shapes
no

Spirilla bacteria can cause rat-bite fever in humans and animals. The bacteria found in spirilla are shaped like cork screws.
Viruses have different geometrical shapes, such as helical and polyhedral shapes. A particular polyhedral shape common to many viruses is a dodecahedron shape. This is a geometric shape that has 12 sides.
The shape of viruses varies greatly. They can be shaped like small balls (spherical viruses) like strands of spaghetti (flexous viruses) rigid rods, like bullets (baciliform viruses) and like geometric shapes (isocohedral viruses) The smallest viruses can be as small as 20nm (20/1,000,000 of a mm) to as much as 2,000 nm for some flexous plant viruses.
