The Bifidobacteriaceae are the only family of bacteria in the order Bifidobacteriales.

The family Bifidobacteriaceae stain [Gram-positive], range from obligate to faculatively anaerobic, are non-motile, non-filamentous and non-spore forming. Their morphology is varied and ranges from Y- or V-shaped (from which the bifidobacteria derived their name) to ones with enlarged or flattened ends (club- or spatula-shaped). The branching nature of Bifidobacteria can change with different starins and media. These rods appear as a solitary bacilli or as aggregates in chains or in clumps.

These chemoorganotrophic microorganisms are saccharolytic acid producers and do not produce gas.

The Bifidobacteriaceae family is divided into ten genera ( Bifidobacterium, Aeriscardovia, Alloscardovia, Bombiscardovia, Galliscardovia, Gardnerella, Neoscardovia, Parascardovia, Pseudoscardovia, and Scardovia, with three candidate genera Candidatus Ancillula, Candidatus Opitulatrix, and Candidatus Servula.
