Spirillum

(spī-ril'ŭm),
A genus of large (1.4-1.7 mcm in diameter), rigid, helical, gram-negative bacteria (family Spirillaceae) that are motile by means of bipolar fascicles of flagella. These freshwater organisms are obligately microaerophilic and chemoorganotrophic, possessing a strictly respiratory metabolism; they neither oxidize nor ferment carbohydrates.
