OVERVIEW:
'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 animalis, B. longum-a, and B. pseudolongum deconjugate malonyl-, acetyl- and β-glucoside conjugates of daidzin, which are found in soy milk, to produce daidzein. These strains are also reported to transform daidzein to equol in soy milk [PMC 4381290]. Identified as a constituent of the oral microbiome by Human Oral Microbiome Database. Consumption of probiotic bacteria such as Bifidobacterium animalis subsp Lactis, Streptococcus thermophiles, Lactobacillus bulgaricus, and Lactococcus lactis subsp Lactis appeared to make study participants less prone to anxiety. B. animalis (coefficient=-0.84; 95% CI -1.61 to -0.07; P=0.03) and M. smithii (coefficient=-0.43, 95% CI -0.90 to 0.05; P=0.08) were negatively associated with the BMI. [PMID: 23459324]
This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
