The bacterium provisionally named Spirillum minus is associated with rat-bite fever.

The species Spirillum minus causes Rat bite fever.

Spirillum minus is a species of Spirillum.

It is caused by the gram-negative rod Spirillum minus (also known as Spirillium minor).

(Notes Spirillum minus is also an agent of rat bite fever, in the form known as sodoku.)

Spirillum minus: Spirochaete causing one type of rat bite fever (see also Streptobacillus moniliformis).

The two species in the Spirillum genus are Spirillum minus and Spirillum pulli.

Rat-bite fever transmitted by the gram-negative coiled rod Spirillum minus (also known as Spirillum minor) is more rare, and is found most often in Asia.

The taxonomic position of three other species provisionally bearing the Spirillum genus name (Spirillum minus, Spirillum pleomorphum, and Spirillum pulli) is uncertain and these have no standing in nomenclature.
