Bifidobacterium is a genus of Gram-positive, non-motile, often branched anaerobic bacteria inhabiting the Gastrointestinal tract and Vagina[1]. Bifidobacteria are one of the major genera of bacteria that make up the gut flora, the bacteria that reside in the colon. Bifidobacteria aid in digestion, are associated with a lower incidence of allergies [2] and also prevent some forms of tumor growth [3]. Some bifidobacteria are used as probiotics.

Before the 1960s, Bifidobacterium species were collectively referred to as "Lactobacillus bifidus".
