Spirillum

This article is about the bacterial genus. For spiral-shaped bacteria in general, see spiral bacteria.

Spirillum is a genus of Gram-negative bacteria within family Spirillaceae.[1][2][3] There are two species in Spirillum with standing in nomenclature, Spirillum winogradskyi and Spirillum volutans.[4] 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.[1][5]

Morphology[edit]

Members of Spirillum are large, elongate, spiral shaped, rigid cells.[5] Some have tufts of flagella at both poles. They are microaerophilic and usually found in stagnant freshwater rich in organic matter.[5]

Pathogenicity[edit]

The bacterium provisionally named Spirillum minus is associated with rat-bite fever.[6]
