STRUCTURAL AND FUNCTIONAL CHARACTERISATION OF MUCUS ADHESION PROTEINS OF LACTOBACILLUS REUTERI
… key mediators in the mucus adhesion of commensal Lactobacillus species. However, knowledge on the structural or functional basis of adhesin interaction with mucin glycoproteins, the main component of mucus, is limited. This work describes the biochemical and structural properties of two …

Investigating the molecular mechanisms of the interactions between Lactobacillus reuteri strains and intestinal mucus
… and the host. Here we used the gut symbiont Lactobacillus reuteri to investigate the molecular mechanisms underlying the interactions between gut bacteria and mucus. Firstly, the mucus binding ability of a collection of L. reuteri strains from different vertebrate hosts was assessed in vitro …

Microbial Ecology of the Porcine Gastrointestinal Tract in Relation to Lactobacillus Reuteri MM53 and Bacitracin Treatments
… was studied after introduction of an exogenous Lactobacillus reuteri strain MM53 in conjunction with bacitracin additions using molecular techniques. Denaturing gradient gel electrophoresis was used to monitor bacterial population changes and these changes were assayed based upon shifts in fecal …

Evaluating oxalate-degrading Lactobacillus spp. for their ability to be used as probiotics in the treatment of kidney stone disease
… it is probably a multifactorial disease. Lactobacillus strains which potentially had increased ability to degrade oxalate were previously isolated from a healthy low kidney stone risk group. The aim of this study was to identify these natural Lactobacillus strains and evaluate their …

Intercellular communication in uropathogenic Escherichia coli and the probiotic Lactobacillus reuter
… Escherichia coli J96, determine if the probiotic Lactobacillus reuteri RC-14 produced AI-2, and evaluate if secreted products from the probiotic could affect pathogen recognition by the host. Disruption of luxS (AI-2 synthesis) in E. coli J96, did not alter growth, motility or biofilm formation, …

The role of mucus in the cross talk between gut bacteria and the host
… the adhesion properties of the gut symbiont Lactobacillus reuteri to mucus. To study the impact of IELs on mucus properties, a γδ T cell-deficient (TCRδ-/-) mouse model was used. TCRδ-/- mice showed increased susceptibility to dextran sodium sulphate (DSS)-induced colitis, alterations in …

A study into the properties and applications of bacterial microcompartments and polyphosphate metabolism
… applications of their components in the cells of Lactobacillus reuteri, and Escherichia coli predominantly, with additional investigation into Yersinia spp. The experimental chapters of this thesis initially investigate the application of bacterial microcompartments as tools for compartmentalizing …

Efficacy of Brushing with Probiotics for the Reduction of Gingivitis
… the efficacy of brushing with the probiotic Lactobacillus reuteri on plaque accumulation and gingival inflammation. This study included 34 healthy adult subjects, ages 18-65, exhibiting gingivitis. Participants were asked to participate in a randomized, double-blind, placebo controlled study …

Characterizing the roles of gut microbiota, probiotic Lactobacilli and CX3CR1 in the development of autoimmunity in MRL/lpr mice
… We previously published that the mixture of Lactobacillus reuteri (L. reuteri), L. oris, L. johnsonii, L. gasseri, and L. rhamnosus significantly attenuated disease in MRL/lpr mice by restoring the imbalance between regulatory T cells and T helper-17 cells. To further understand the role of …

EVALUATION OF TWO ORAL PROBIOTIC PRODUCTS FOR MICROBIAL VIABILITY AND IN VITRO INHIBITION OF SELECTED PERIODONTAL BACTERIAL PATHOGENS.
… strains of the gram-positive, aerobic species Lactobacillus reuteri, and EvoraPlus (Oragenics), with freeze-dried strains of the gram-positive, aerobic species Streptococcus oralis, Streptococcus uberis, and Streptococcus rattus, are two recently-introduced commercial oral probiotic products …

Role of antiretroviral therapy exposure host genetics on cytomegalovirus infection status and association with gut microbiome profiles among pregnant black African women
… controls (p2). Significantly lower abundance of Lactobacillus reuteri and Roseburia, genera associated with lower microbial translocation was observed in cases than controls. Lower relative abundance of Lactobacillus and Roseburia, is consistent with microbial translocation and heightened …
