[4] Members of this family are mostly anaerobic, non-motile (with the exception of some Gordonibacter and Senegalimassilia species that exhibit motility), asaccharolytic and do not form spores.
[4] Some species have also been isolated from human samples of periodontal or endodontic infections, Crohn's disease and severe blood bacteremia.
[4] Analysis of genome sequences identified 13 conserved signature indels (CSIs) in diverse proteins that are exclusively present in different Eggerthellaceae species.
[1][4] The identified CSIs provide reliable and important means to distinguish members of Eggerthellaceae from all other Coriobacteriia as well as other bacteria.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN).
