''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''.〔(Bifidobacterium )〕〔 〕〔Rapid Identification, Differentiation, and Proposed New Taxonomic Classification of Bifidobacterium lactis. Appl Environ Microbiol. 2002 December; 68(12): 6429–6434.〕 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 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. Chr. Hansen A/S 〔http://www.chr-hansen.com/〕 from Denmark has a similar claim on a strain of ''Bifidobacterium animalis'' subsp. ''lactis'', marketed under the trademark BB-12.〔http://www.chr-hansen.com/products/product-areas/probiotics-for-dietary-supplements/strains/bb-12r.html〕 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.〔http://www.theralac.com/inside-theralac.aspx〕 The strain "Bifidobacterium lactis HN-019" is sold in a variety of commercial probiotics, among them Attune Wellness Bars〔http://www.powerofprobiotics.com/HOWARU-Bifido.html〕 and NOW Foods Clinical GI Probiotic.〔http://www.swansonvitamins.com/now-foods-clinical-gi-probiotic-60-veg-caps?SourceCode=INTL405&CAWELAID=530002460000003647&mkwid=HIJ1PZQi&pcrid=49285705567&gclid=CMS377XSxL0CFUYV7AodbVAAaQ〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bifidobacterium animalis」の詳細全文を読む スポンサード リンク
