Bifidobacterium bifidum is a bacterial species of the genus Bifidobacterium. B. bifidum is one of the most common probiotic bacteria that can be found in the body of mammals, including humans.

Structure and characteristics[edit]

Since B. bifidum is a Gram-positive bacterium that is not motile, anaerobic, and not spore-forming. The bacterium is rod-shaped and can be found living in clusters, pairs, or even independently. The majority of the population of B. bifidum is found in the colon, lower small intestine, breast milk, and often in the vagina.[citation needed]


The use of B. bifidum in probiotic applications may reduce the chances of acute diarrhea and the risk of E. coli infections, and contributes to the maintenance of vaginal homeostasis.[4]

Health concerns[edit]

The manipulation of the gut flora is complex and may cause bacteria-host interactions.[5] Although probiotics, in general, are considered safe, there are concerns about their use in certain cases.[5][6] Some people, such as those with compromised immune systems, short bowel syndrome, central venous catheters, heart valve disease and premature infants, may be at higher risk for adverse events.[7] Rarely, consumption of probiotics may cause bacteremia, and sepsis, potentially fatal infections in children with lowered immune systems or who are already critically ill.[8]
