Comparative microbial genome analysis of lactobacilli
… and probiotic properties. Exploiting lactobacilli has been complicated by metabolic diversity, unclear species identity and uncertain relationships between them and other commercially important lactic acid bacteria. Comparative Genomics is becoming increasingly important as a method of …

Intestinal delivery of heterologous peptides with lactobacilli
… the efficiency of oral tolerance induction, lactobacilli were developed as a tool to deliver heterologous protein into the gastrointestinal tract. Lactobacillus spp. are a potential delivery vehicle for oral antigens because of their generally regarded as safe (GRAS) status, ability to …

In-Vivo and In-Vitro Cholesterol Removal by Lactobacilli and Bifidobacteria
… to taurineconjugated bile. Most strains of lactobacilli and bifidobacteria exhibited highest total BSH activity (1.60-1.99 U/mL for lactobacilli and 0.87-1.39 U/mL for bifidobacteria) in bile salt mixture (2.8 mM sodium glucocholate and 1.2 mM sodium taurocholate) than individual conjugated …

Characterization of the intestinal microbiome and lactobacilli community: influence of dietary and environmental factors
… in neonatal piglets’ intestinal microbiome and lactobacilli community structure research. In Chapter 2, the latest progress of methods used in microbiota research were described and compared, the known impact of different environmental and dietary factors were discussed. In Chapter 3, a new …

Characterizing the roles of gut microbiota, probiotic Lactobacilli and CX3CR1 in the development of autoimmunity in MRL/lpr mice
… we continued our investigation of the role of Lactobacilli in the pathogenesis of lupus-like disease 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 …

Characterisation of the HIV inhibitory activity of vaginal lactobacilli isolates from young South African women at high risk of HIV acquisition
… to evaluate the immunoregulatory properties of lactobacilli, and determine the mechanisms underlying these relationships. Vaginal Lactobacillus isolates (n=103), including L. crispatus, L. jensenii, L. johnsonii, L. mucosae, L. plantarum, L. ruminis, L. salivarius and L. vaginalis, were isolated …

Mechanisms of Immunomodulation By Probiotics: Influence of Lactobacilli On Innate and T Cell Immune Responses Induced By Rotavirus Infection and Vaccines
… mechanisms of immunomodulation by probiotic lactobacilli on innate and T cell immune responses induced by rotavirus infection and vaccines in a gnotobiotic pig model of human rotavirus (HRV) infection and vaccination. We first studied the effects of probiotics on antigen-presenting cells …

Potential for probiotics to mitigate environmental stress in Western honey bees
The use of probiotics, particularly strains of lactobacilli, presents a promising strategy for addressing key threats to Apis mellifera, such as Varroa mites and Paenibacillus larvae. Lactobacilli are part of the honey bee hindgut microbiota, and some probiotic strains have been shown to enhance …

Gene expression patterns of the female genital tract and immunomodulation by Lactobacillus species
… included in this study. The effects of these lactobacilli on cytokine production by vaginal epithelial (VK2) cells stimulated with Gardnerella vaginalis (ATCC 14018) were tested in vitro, RNA was extracted and used for Affymetrix Genechip whole transcript microarray analysis. This study found …

Probiotic metabolism of human milk oligosaccharides (HMOs) and prebiotics
… (GlcNAc) was widely used by the lactobacilli, but B. breve ATCC15700 was the only bifidobacteria strain that could utilize this carbohydrate, (2) none of the bifidobacteria and very few lactobacilli could utilize either free L-fucose (L. rhamnosus GG and L. rhamnosus DR20) or …

A metagenomic approach to understanding the relationship between the vaginal microbiome and women’s reproductive health
… Healthy women’s vaginas are mainly dominated by Lactobacilli at reproductive age. The predominance of Lactobacilli is coincident with the rise in estrogen levels and glycogen content in the vaginal epithelium. Estrogen levels increase gradually during pregnancy and drop down at post-partum. …

Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… stimulate the growth of bifidobacteria and lactobacilli in infants. Microbial analysis of infants fed prebiotics is restricted to measuring alterations in the fecal microbiota. Typically, prebiotics are fermented in the ascending colon, and the fecal microbiota may not be an appropriate …

EVALUATION OF TWO ORAL PROBIOTIC PRODUCTS FOR MICROBIAL VIABILITY AND IN VITRO INHIBITION OF SELECTED PERIODONTAL BACTERIAL PATHOGENS.
… study was to determine whether PerioBalance lactobacilli and EvoraPlus streptococci are viable upon product use, and possess in vitro inhibitory effects against fresh clinical strains of the putative periodontal bacterial pathogens, Tannerella forsythia and Prevotella intermedia/nigrescens, …

Effects of subtherapeutic doses of antibiotics on poultry intestinal bacteria
… The ileal flora also was predominantly lactobacilli (average 75% of the flora). The most common lactobacilli from the turkey intestinal tract were several previously undescribed Lactobacillus species followed by L. acidophilus, L. salivarius subsp. salivarius, L. fermentum, and L. …

Pet food: quality and quality improvement
… 8, and 24 hours for analysis (ammonia, SCFA, pH, lactobacilli, enterococci, coliforms, clostridia). Consequently, the L. animalis strain was fed to nine dogs having lactobacilli counts lower than 4.5 Log CFU per g of faeces. The study indicated that the L animalis strain was able to survive …

Molecular Characterization of the Heat Shock-Regulatedgroesl Operon in Lactobacillus Zeae Strain 102S
Various species of lactobacilli are used in the fermentation and preservation of food and dairy products. Due to the enhanced safety of such products, and perceived health-beneficial properties attributed to the ingestion of many strains, new biotechnological applications for lactobacilli are being …
