Spiral bacteria

Spiral bacteria form the third major morphological category of prokaryotes, along with the rod-shaped bacilli and spherical cocci.[1][2] Spiral bacteria can be sub-classified based on the number of twists per cell, cell thickness, cell flexibility, and motility.


Spirillum (plural spirilla) refers to rigid spiral bacteria that are Gram-negative and frequently amphitrichous or lophotrichous. Examples include:


Spirochete (plural spirochetes) refers to very thin, elongate, flexible, spiral bacteria that are motile via endoflagella. Owing to their morphological properties, spirochetes are difficult to Gram-stain but may be visualized using dark field microscopy or Warthin–Starry stain.[3] Examples include:


Vibrio (plural vibrios) refers to Gram-negative, comma-shaped rods with a partial twist. One notable example includes:
