The
order Flavobacteriales comprises several families of environmental
bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among ...

Comparative genomics and molecular signatures
''Flavobacteriales'' is of one of the orders from the phylum ''
Bacteroidota
The phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and ...

Comparative genomic studies have identified several conserved

Indel is a molecular biology term for an insertion or deletion of bases in the genome of an organism. It is classified among small genetic variations, measuring from 1 to 10 000 base pairs in length, including insertion and deletion events that ...
s, as well as 27 proteins that are uniquely shared by different sequenced Flavobacteriales and Bacteroidota species supporting this inference.
Additionally, these studies have also identified 38 proteins that seem to be specific for the species from the order ''Flavobacteriales''.
Of these proteins, 26 were present in all sequenced species, while the remaining 12 were missing in only one or two species. These signature proteins provide potential molecular markers for this order. Several proteins have also been identified which are unique to the ''Flavobacteriales'' and ''
Bacteroidales
Bacteroidales is an order of bacteria. Notably it includes the genera ''Prevotella'' and ''Bacteroides'' , which are commonly found in the human gut microbiota.
