Spirobacillus cienkowskii sp. nov.

Submitted by Angst, Pascal

Genus Spirobacillus

Etymology
[Spi.ro.ba.ci'llus] Gr. fem. n. speîra, coil or spiral, referring to this organism spiral shape; L. masc. n. bacillus, cylindrical or rodlike bacterium; N.L. masc. n. Spirobacillus, rodlike bacterium, having a spiral shape
Nomenclatural type
Species Spirobacillus cienkowskiiTs
Description
Spirobacillus, described initially by Elya Metchnikoff (1889). Proteobacteria of the order Silvanigrellales. Morphologically distinct as tightly coiled bacteria (3.50 m in length by 1.07 m in width), production of a pink carotenoid. Infects the hemolymph of multiple species of Daphnia. Basis of assignment: 16S rRNA gene sequence GenBank accession number EU220836, oligonucleotide sequence S-*-Smet-1459-a-A-18 complementary to unique region of the 16S rRNA gene. Yet to be cultivated.
Classification
