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[edit source | edit]

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 and Bulgaria) 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] It is marketed both as Bifidobacterium animalis and Bifidobacterium lactis, however, the true scientific name of the strain is Bifidobacterium animalis subsp lactis.[5]

Lidl lists "Bifidobacteria BB12" in its "Proviact" yoghurt.

Health effects[edit source | edit]

It is worth noting that many scientific studies are funded by companies that produce products which contain the substance being studied, which can lead to doubts about the impartiality of these studies.[6] The bodies that have funded the research below are not listed.
