Abstract
Selenomonas sputigena is an anaerobic, motile, crescent-shaped, gram-negative bacterium found in the human oral cavity that is associated with dental caries and periodontitis. Strain ATCC 33150 was replaced as the type strain for S. sputigena and was described as atypical, as it fermented arabinose and displayed a unique pattern by polyacrylamide electrophoresis compared to other isolates. The genome of the atypical strain, ATCC 33150, is 2,601,282 base pairs in length, comprising 2,342 protein-coding genes, and a 54.68% GC content.
