Order of bacteria
The Selenomonadales are an order of bacteria within the class Negativicutes ; unlike most other members of Bacillota , they are Gram-negative . The phylogeny of this order was initially determined by 16S rRNA comparisons.[1] More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species.[2] On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes . Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae.[2] Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.[3]
