B. a. animalis
Bifidobacterium animalis and Bifidobacterium lactis were previously described as two distinct species. Presently, both are considered B. animalis with the subspecies Bifidobacterium animalis subsp. animalis and Bifidobacterium animalis subsp. lactis.
Both old names B. animalis and B. lactis are still used on product labels, as this species is frequently used as a probiotic. In most cases, which subspecies is used in the product is not clear.
Several companies have attempted to trademark particular strains, and as a marketing technique, have invented scientific-sounding names for the strains.
Danone (Dannon) markets the subspecies strain DN 173 010 as Bifidus Digestivum (UK), Bifidus Regularis (US and Mexico), Bifidobacterium Lactis or B.L. Regularis (Canada), DanRegularis (Brazil), Bifidus Actiregularis (Argentina, Austria, Belgium, Bulgaria, Chile, Czech Republic, France, Germany, Greece, Hungary, Israel, Italy, Kazakhstan, Netherlands, Portugal, Romania, Russia, South Africa, Spain and the UK), and Bifidus Essensis in the Middle East (and formerly in Hungary, Bulgaria and The Netherlands) through Activia from Safi Danone KSA.
Lidl lists "Bifidobacterium BB-12" in its "Proviact" yogurt.
Bifidobacterim animalis subspecies lactis BB-12 administered in combination with other probiotics has showed a small beneficial effect in a study of 32 patients with ulcerative colitis.
The manipulation of the gut flora is complex and may cause bacteria-host interactions. Although probiotics, in general, are considered safe, there are concerns about their use in certain cases. 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. Rarely, consumption of probiotics may cause bacteremia, and sepsis, potentially fatal infections in children with lowered immune systems or who are already critically ill.
