Biodiversity of Intestinal Lactic Acid Bacteria in the Healthy Population.

The complex ecosystem of the gastrointestinal tract involves tight interrelations among host cells, diet, and billions of microbes, both beneficial and opportunistic pathogens. In spite of advanced genomic, metagenomic, and metabonomic approaches, knowledge is still quite limited regarding the biodiversity of beneficial microbiota, including Lactobacillus spp., and its impact on the main biomarkers of general health.

New insights into the impact of Lactobacillus population on host-bacteria metabolic interplay.

We aimed at evaluating the association between intestinal Lactobacillus sp. composition and their metabolic activity with the host metabolism in adult and elderly individuals. Faecal and plasma metabolites were measured and correlated to the Lactobacillus species distribution in healthy Estonian cohorts of adult (n = 16; < 48 y) and elderly (n = 33; > 65 y).

Impact of probiotic Lactobacillus plantarum TENSIA in different dairy products on anthropometric and blood biochemical indices of healthy adults.

The blood pressure-lowering effect of dairy products holds the potential to decrease the risk of cardiovascular disease (CVD). An open question is if the successful expression of functional properties of the probiotic strain depends on host biomarkers and/or food matrix properties. The probiotic Lactobacillus plantarum strain TENSIA® (DSM 21380) is a novel microorganism with antimicrobial and antihypertensive functional properties.

Hypocaloric diet supplemented with probiotic cheese improves body mass index and blood pressure indices of obese hypertensive patients--a randomized double-blind placebo-controlled pilot study.

Background: Gut lactobacilli can affect the metabolic functions of healthy humans. We tested whether a 1500 kcal/d diet supplemented with cheese containing the probiotic Lactobacillus plantarum TENSIA (Deutsche Sammlung für Mikroorganismen, DSM 21380) could reduce some symptoms of metabolic syndrome in Russian adults with obesity and hypertension.

Methods: In this 3-week, randomized, double-blind, placebo-controlled, parallel pilot study, 25 subjects ingested probiotic cheese and 15 ingested control cheese.

[Effect of probiotic Heart cheese "Harmony" comprising bacteria L. plantarum TENSIA DSM 21380 on blood pressure and metabolic health indices].

Safety of a probiotic cheese containing Lactobacillus plantarum Tensia according to a variety of health indices in different age groups.

Safety of the probiotic Lactobacillus plantarum strain Tensia (DSM 21380) was tested in vitro, in semihard Edam-type cheese, in an animal model and after consumption of the probiotic cheese in double-blind randomized placebo-controlled human intervention studies with different age groups. The susceptibility of L. plantarum Tensia to 8 antibiotics, and the presence of tetracycline (tet M, S, O, K, L) genes and class 1 integron was assessed by applying epsilometer-test and PCR-based methods.

Diversity and metabolic impact of intestinal Lactobacillus species in healthy adults and the elderly.

The present study aimed at assessing the counts and species distribution of intestinal lactobacilli and exploring if the data are associated with BMI and blood glucose level in healthy adults and elderly persons. The BMI (P < 0·01), the level of fasting blood glucose (P < 0·001) and the total counts of lactobacilli (P < 0·01 by bacteriology; P < 0·001 by real-time PCR) were higher in the elderly. The number of species in adults was lower (P < 0·05), who were more often colonised with Lactobacillus acidophilus (P = 0·031) and L.

Complete glutathione system in probiotic Lactobacillus fermentum ME-3.

There is much information about glutathione (GSH) in eukaryotic cells, but relatively little is known about GSH in prokaryotes. Without GSH and glutathione redox cycle lactic acid bacteria (LAB) cannot protect themselves against reactive oxygen species. Previously we have shown the presence of GSH in Lactobacillus fermentum ME-3 (DSM14241).

Evaluation of the functional efficacy of an antioxidative probiotic in healthy volunteers.

Background: In persons without clinical symptom it is difficult to assess an impact of probiotics regarding its effect on health. We evaluated the functional efficacy of the probiotic Lactobacillus fermentum ME-3 in healthy volunteers by measuring the influence of two different formulations on intestinal lactoflora, fecal recovery of the probiotic strain and oxidative stress markers of blood and urine after 3 weeks consumption.

Methods: Two 3-week healthy volunteer trials were performed.
