Anchorless cell surface proteins (CSPs) were extracted with 1 M lithium chloride solution from Lactobacillus rhamnosus FSMM22. Loss of the anchorless CSPs resulted in a two-fold decrease in FSMM22 cells bound to a constitutive extracellular matrix glycoprotein, laminin, in vitro. DNA-binding protein HU, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase, and 30S ribosomal protein S19 (RpsS) were identified by mass spectrometry in the extract as laminin-binding adhesins. Among the four proteins, RpsS was immunohistochemically confirmed to exist on the cell surface...

Diarrhea is considered as an important cause of morbidity and mortality, even though one of the main reasons of death following diarrhea is initiated by dysentery. In recent years, the consumption of probiotics has been proposed for the treatment of infectious diarrhea. Despite most of the studies on probiotics have focused on acute watery diarrhea, few studies in the field of dysentery have found beneficial effects of probiotics. This study is a randomized double-blind clinical trial. The patients were randomly placed into control and case groups...

The prevalence of inflammatory bowel disease (IBD) has increased in Western countries during the course of the twentieth century, and is evolving to be a global disease. Recently we showed that a bacterial meal of a non-commensal, non-pathogenic methanotrophic soil bacterium, Methylococcus capsulatus Bath prevents experimentally induced colitis in a murine model of IBD. The mechanism behind the effect has this far not been identified. Here, for the first time we show that M. capsulatus, a soil bacterium adheres specifically to human dendritic cells, influencing DC maturation, cytokine production, and subsequent T cell activation, proliferation and differentiation...

Matrix composition plays a crucial role in the controlled release of viable and functional bacteria in the intestine. Imaging tools such as electronic and confocal microscopies were used in this work to investigate the influence of matrix composition on matrix integrity and porosity, bacterial spatial distribution and viability during simulated in vitro digestion. L. rhamnosus GG was encapsulated in matrices having different casein/whey protein ratios. The formulation with a casein/whey ratio of 60/40 presented a porous weak gel structure that resulted in its fast disintegration in gastric media showing the presence of dead bacteria in the intestine...

Probiotics have been described as a potential strategy to control opportunistic infections due to their ability to stimulate the immune system. Using the non-vertebrate model host Galleria mellonella, we evaluated whether clinical isolates of Lactobacillus spp. are able to provide protection against Candida albicans infection. Among different strains of Lactobacillus paracasei, Lactobacillus rhamnosus and Lactobacillus fermentum, we verified that L. paracasei 28.4 strain had the greatest ability to prolong the survival of larvae infected with a lethal dose of C...

The objective of this study was to determine whether Lactobacillus rhamnosus GG culture supernatant (LCS) has a preventive effect against gut-derived systemic neonatal Escherichia coli (E. coli) K1 infection. The preventive effects were evaluated in human colonic carcinoma cell line Caco-2 and neonatal rat models. Our in vitro results showed that LCS could block adhesion, invasion and translocation of E. coli K1 to Caco-2 monolayer via up-regulating mucin production and maintaining intestinal integrity. In vivo experiments revealed that pre-treatment with LCS significantly decrease susceptibility of neonatal rats to oral E...

Graft-versus-host-disease (GVHD) is a major adverse effect associated with allogeneic stem cell transplant. Previous studies in mice indicated that administration of the probiotic Lactobacillus rhamnosus GG can reduce the incidence of GVHD after hematopoietic stem cell transplant. Here we report results from the first randomized probiotic enteric regimen trial in which allogenic hematopoietic stem cell patients were supplemented with Lactobacillus rhamnosus GG. Gut microbiome analysis confirmed a previously reported gut microbiome association with GVHD...

BACKGROUND: Emerging evidence suggested that the prebiotic ability of β-glucan was intimately related to its molecular weight (Mw ). However, the effect of oat β-glucan with different Mw on gut homeostasis was inconsistent. Importantly, the understanding of the fermentation properties of oat β-glucan fractions was still limited. The aim of this study was to evaluate the prebiotic potential of raw and hydrolyzed oat β-glucan during in vitro fermentation by fecal microbiota and selected probiotic strains...
