Spirillum Spirillum winogradskyi Spirillum volutans

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

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

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