BACKGROUND Lactobacillus spp. potentially contribute to health by modulating bacterial biofilm formation, but their effects on the overall oral microbiota remain unclear. METHODS AND FINDINGS Oral microbiota was characterized via 454-pyrosequencing of the 16S rDNA hypervariable region V3-V4 after 12 weeks of daily Lactobacillus reuteri DSM 17938 and PTA 5289 consumption. Forty-four adults wer...
Beneficial microbes and probiotic species, such as Lactobacillus reuteri, produce biologically active compounds that can modulate host mucosal immunity. Previously, immunomodulatory factors secreted by L. reuteri ATCC PTA 6475 were unknown. A combined metabolomics and bacterial genetics strategy was utilized to identify small compound(s) produced by L. reuteri that were TNF-inhibitory. Hydrophi...
Lactobacillus reuteri is a powerful probiotic and adjunct functional culture candidate received a lot of scientific attention as it is one of the few endogenous “Lactobacillus” species found in the gastrointestinal tract of vertebrates, including humans, rats, pigs and chicken. The organism has been widely utilized as a probiotic in humans and animals for many years. In the present work L. reut...
Recent research has provided mechanistic insight into the important contributions of the gut microbiota to vertebrate biology, but questions remain about the evolutionary processes that have shaped this symbiosis. In the present study, we showed in experiments with gnotobiotic mice that the evolution of Lactobacillus reuteri with rodents resulted in the emergence of host specialization. To iden...
Lactic acid bacteria (LAB) produce exopolysaccharides (EPS) that are important for biofilm formation in the mammalian oral cavity and gastrointestinal tract. Sucrose is a well-known substrate for homo-EPS formation by Lactobacillus reuteri glucansucrases (GS). Starch is the main fermentable carbohydrate in the human diet, and often consumed simultaneously with sucrose. Recently we have characte...
Wall, T. 2005. Environmental Interactions of Lactobacillus reuteri – Signal Transduction, Gene Expression and Extracellular Proteins of a Lactic Acid Bacterium. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-6903-1 The commensal bacterium Lactobacillus reuteri inhabits the human gastrointestinal tract and possesses putative probiotic, i.e. health-promoting, properties. In this thesis, featu...
We hypothesized that giving the probiotic strain Lactobacillus reuteri (L. reuteri) DSM 17938 to preterm, formula-fed infants would prevent an early traumatic intestinal inflammatory insult modulating intestinal cytokine profile and reducing the onset of feeding intolerance. Newborn were randomly allocated during the first 48 h of life to receive either daily probiotic (10⁸ colony forming units...
OBJECTIVES To evaluate whether daily administration of Lactobacillus reuteri DSM 17938 reduces the frequency and duration of diarrheal episodes and other health outcomes in day school children in Mexico. METHODS Healthy children (born at term, aged 6-36 months) attending day care centers were enrolled in this randomized, double-blind, placebo-controlled trial. They received L reuteri DSM 1793...
A Lactobacillus reuteri strain isolated from sourdough is known to produce the vitamin cobalamin. The organism requires this for glycerol cofermentation by a cobalamin-dependent enzyme, usually termed glycerol dehydratase, in the synthesis of the antimicrobial substance reuterin. We show that the cobalamin-synthesizing capacity of another L. reuteri strain (20016, the type strain, isolated from...
OBJECTIVE Two randomized controlled clinical trials have shown that Lactobacillus (L) reuteri DSM 17938 reduces the duration of diarrhea in children hospitalized due to acute infectious diarrhea. This was the first trial evaluating the efficacy of L. reuteri DSM 17938 in outpatient children with acute infectious diarrhea. METHODS This was a multicenter, randomized, single-blinded, case contro...
