Bifidobacterium animalis is a Gram-positive anaerobic rod-shaped bacterium which can be found in the large intestines of most mammals, including humans.
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.[1][2][3]
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 it is not clear which subspecies is used in the product.
Trade names
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.[citation needed]
Chr. Hansen A/S [4] from Denmark has a similar claim on a strain of Bifidobacterium animalis subsp. lactis, marketed under the trademark BB-12.[5]
Lidl lists "Bifidobacterium BB-12" in its "Proviact" yogurt.
Therelac contains the strains "Bifidobacterium lactis BI-07" and "Bifidobacterium lactis BL-34" (also called BI-04) in its probiotic capsule.[6]
The strain "Bifidobacterium lactis HN-019" is sold in a variety of commercial probiotics, among them Attune Wellness Bars[7] and NOW Foods Clinical GI Probiotic.[8]

Studies
A 2007 study conducted in cooperation with the Groupe Danone, Dannon's parent company, took 274 adult subjects diagnosed with IBS (Irritable Bowl Syndrome) to study the effects of Bifidobacterium animalis on their symptoms. Over the first 2-3 week period, the subject's stool samples and symptoms were recorded. The subjects were then asked to consume two servings of fermented milk twice a day. Bifidobacterium animalis was in the fermented milk. The results suggested some beneficial effect on discomfort and bloating in constipation-predominant IBS.[9]
Products
Bifidobacterium animalis is present in many food products and dietary supplements. The probiotic is mostly found in dairy products. [10]
