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]
