the aim of this study was to determine the suitability of different doses (0, 0.4, 0.8 and 1.2%) of coffee extract on fermentation and survival of lactobacillus acidophilus and bifidobacterium bifidum in milk and yoghurt. the produced samples were examined in terms of ph, acidity and microbial count during incubation period and permanence. the number of lactobacillus acidophilus and bifidobacte...

background: the present work was planned to evaluate the antihyperglycemic, lipid‑lowering, and antioxidant effect of lactobacillus casei and bifidobacterium bifidum in streptozotocin (stz)‑induced diabetic rats. methods: single daily dose of 1 × 107 cfu/ml of l. casei and b. bifidum alone and in combination of both was given to wistar rats orally by gavaging for 28 days. glucose tolerance test...

BACKGROUND Because of changes in gut physiology, immune system reactivity, and diet, elderly people are more susceptible to gastrointestinal infections than are younger adults. The gut microflora, which provides a natural defense against invading microorganisms, changes in elderly people with the development of potentially damaging bacterial populations, which may lead to alterations in bacteri...

Bifidobacterium bifidum BGN4 is a probiotic strain that has been used as a major ingredient to produce nutraceutical products and as a dairy starter since 2000. The various bio-functional effects and potential for industrial application of B. bifidum BGN4 has been characterized and proven by in vitro (i.e., phytochemical bio-catalysis, cell adhesion and anti-carcinogenic effects on cell lines, ...

Bifidobacteria are considered dominant and for this reason key members of the human gut microbiota, particularly during the first one to two years following birth. A substantial proportion of the bifidobacterial population in the intestine of infants belong to the Bifidobacterium bifidum taxon, whose members have been shown to display remarkable physiological and genetic features involving adhe...

The aim of the study was to compare the compositions of the fecal microbiotas of infants fed goat milk formula to those of infants fed cow milk formula or breast milk as the gold standard. Pyrosequencing of 16S rRNA gene sequences was used in the analysis of the microbiotas in stool samples collected from 90 Australian babies (30 in each group) at 2 months of age. Beta-diversity analysis of tot...

BACKGROUND AND PURPOSE Nonylphenol (NP) is a well-known environmental hormone recognized as detrimental to the reproductive systems of aquatic animals and humans. The effect of NP on probiotics in the human gastrointestinal tract remains unclear. This study investigated the effect of NP on the growth of Lactobacillus acidophilus and Bifidobacterium bifidum. METHODS L. acidophilus and B. bifid...

The antibacterial activity of Lactobacillus casei IMV B-7280, Lact. acidophilus IMV B-7279, Bifidobacterium longum VK1, and B. bifidum VK2 strains or their various compositions in relation to Staphylococcus aureus in vitro and on models of experimental intravaginal staphylococcosis of mice was determined. It was found that under the influence of these strains and their various compositions, the...

In this work we analyzed the immune activation properties of different Bifidobacterium strains in order to establish their ability as inductors of specific effector (Th) or regulatory (Treg) responses. First, we determined the cytokine pattern induced by 21 Bifidobacterium strains in peripheral blood mononuclear cells (PBMCs). Results showed that four Bifidobacterium bifidum strains showed the ...
