Abstract: Complications of pregnancy are associated with adverse outcomes for mother and baby in the short and long term. The gut microbiome has been identified as a key factor for maintaining health outside of pregnancy and could contribute to pregnancy complications. In addition, the vaginal and the recently revealed placental microbiome are altered in pregnancy and may play a role in pregnancy complications. Probiotic supplementation could help to regulate the unbalanced microflora composition observed in obesity and...

Abstract: Preventing vibriosis in juvenile cultured Turbot Scophthalmus maximus caused by Vibrio anguillarum frequently requires the use of feed supplemented with antibiotics in addition to vaccines. Whether the use of probiotics instead of antibiotics in juvenile Turbot is a safer strategy requires more study. The antibacterial potential of 148 Vibrio spp. strains (mostly isolated from cultures of healthy oysters, clams, and Turbot) was analyzed in vitro against V. anguillarum and other pathogens by means of an agar...

Abstract: Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen of major public health importance. Colonisation precedes infection; thus reducing MRSA carriage may be of benefit for reducing infection. Probiotics represent a novel approach to reducing MRSA carriage. We undertook a pilot feasibility randomised controlled trial of the tolerability and acceptability of probiotics for reducing nasal and intestinal carriage of MRSA. In addition, subjects were screened for vancomycin-resistant enterocococci (VRE)....

Abstract: This study investigated the anti-Candida activity of methanol extracts from freeze-dried probiotic cells and the isolation of some constituents in the extracts. The MIC values of the probiotic methanol cell extracts against Candida albicans ranged between 1.25 and 5mg/ml after 48h of incubation. However, Lactococcus latics subsp. lactis strain X and Lactobacillus casei strain B extracts had an MIC of 10mg/ml after 48h of incubation. The extracts had fungistatic rather than fungicidal activity. These extracts...

Abstract: Most known antibiotics from bacteria are produced by Actinobacteria. However, little is known about the community structure and diversity of fecal actinobacteria from rabbit feces. To investigate the actinobacterial community structure in rabbit feces, different actinobacterial-specific primer sets were used to amplify the overlap regions of 16S rRNA genes from the same DNA. At the genus level, 12 actinobacterial genera were detected by the L and S libraries. Arthrobacter, Brachybacterium, Dietzia, Leucobacter,...

Abstract: Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory disorder of the gut. Although the precise cause of IBD remains unknown, the most accepted hypothesis of IBD pathogenesis to date is that an aberrant immune response against the gut microbiota is triggered by environmental factors in a genetically susceptible host. The advancement of next-generation sequencing technology has enabled identification of various alterations of the gut microbiota composition in IBD. While some results related...

Abstract: Cationic antimicrobial peptides are considered promising candidates to complement currently used antibiotics, which are less effective against increasingly resistant pathogens. To determine the mechanism of action of these peptides, a better understanding of each molecular determinant involved in their membrane interactions is of great importance. In this study, we have focused on the role of electrostatic interactions and amphiphilicity on the membrane interactions since the large majority of natural antimicrobial...

Abstract: Lactic acid bacteria (LAB) are well known for their beneficial effects on human health in the intestine and immune system; however, there are few studies on the impact they can generate in oral health. The aim of this study was to test and compare in vitro antimicrobial activity of L. reuteri on pathogenic bacteria involved in the formation of dental caries: S. mutans, S. gordonii, and periodontal disease: A. naeslundii and T. forsythia. Also, we determined the growth kinetics of each bacterium involved in this...

Abstract: BackgroundSpecific probiotics prevent NEC. A mixture of lactobacilli and bifidobacteria (Infloran) was highly effective in Asian very low birth weight (VLBW) infants. We analyzed the effect of Infloran on NEC, NEC severity and the influence of enteral feedings (breast milk vs. formula) on NEC prevention in a cohort of European VLBW infants.MethodsInfloran was implemented for routine use at our department. VLBW infants receiving probiotics were prospectively followed (2010-12) and compared to historic controls...

Abstract: The recent developments of metagenomics permit an extremely high-resolution molecular scan of the intestinal microbiota giving new insights and opening perspectives for clinical applications. Beyond the unprecedented vision of the intestinal microbiota given by large-scale quantitative metagenomics studies, such as the EU MetaHIT project, functional metagenomics tools allow the exploration of fine interactions between food constituents, microbiota and host, leading to the identification of signals and intimate...

Abstract: INTRODUCTION AND HYPOTHESIS: Recurrent urinary tract infections (UTIs) are more common in women and are frequently defined as ≥2 episodes in the last 6 months or ≥3 episodes in the last 12 months. In a primary care setting, 53 % of women above the age of 55 years and 36 % of younger women report a recurrence within 1 year. Thus, management and prevention of recurrent UTI is of utmost significance. This review aims to highlight the latest research in prevention strategies and suggest...

Abstract: Atopic dermatitis (AD), named also atopic eczema, is a chronic relapsing inflammatory skin disease with a considerable social and economic burden. The primum movens of AD is in most cases a genetic and/or immune-supported defect of the skin barrier, facilitating penetration and sensitization to food or airborne allergens, as well as infections by S. aureus, herpes simplex virus or other microbes. New pathogenetic concepts have generated new approaches to prevention and therapy of AD. In particular, the daily...

Abstract: PURPOSE: Probiotics may confer health benefits for the host. Although Lactobacillus has demonstrated to stimulate the immune response, only a few strains have demonstrated immunomodulatory properties. The newly identified Lactobacillus plantarum strains CECT7315 and CECT7316 (LP3457) seem to boost the immune system in individuals that immune decline. We aimed to investigate whether LP3457 protects against inflammation and the mechanism behind.METHODS: LP3457 potential anti-inflammatory effects were assessed...

Abstract: The use of probiotics as food components combats not only cardiovascular diseases but also many gastrointestinal tract disorders. Their health benefits along with their increased global market have interested scientists for better formulation and appropriate administration to the consumers. However the lack of clear elucidation of their cholesterol lowering mechanisms, have complicated their proper dosage and administration to the beneficiaries. In this review, proposed mechanisms of cholesterol reduction such...

Abstract: The human gut microbiome impacts human brain health in numerous ways: (1) Structural bacterial components such as lipopolysaccharides provide low-grade tonic stimulation of the innate immune system. Excessive stimulation due to bacterial dysbiosis, small intestinal bacterial overgrowth, or increased intestinal permeability may produce systemic and/or central nervous system inflammation. (2) Bacterial proteins may cross-react with human antigens to stimulate dysfunctional responses of the adaptive immune system....

Abstract: The effect of Lactobacillus and Bifidobacterium on human health has been examined for many years. Numerous in vivo and in vitro studies have confirmed the beneficial activity of some exogenous lactic acid bacteria in the treatment and prevention of rotaviral infection, antibiotic-associated diarrhea, inflammatory bowel disease and other gastrointestinal disorders. Probiotics support the action of the intestinal microflora and exhibit a favorable modulatory effect on the host's immune system. However, it should...

Abstract: After the discovery of Helicobacter pylori (H. pylori), and the evidence of its relationship with gastric diseases, antibiotic-based therapies were developed, which efficacy was however limited by antibiotic resistance and lack of patient compliance. A vaccine would overcome these drawbacks, but currently there is not any H. pylori vaccine licensed. In the frame of the studies aimed at finding alternative therapies or at increasing the efficacy of the current ones and/or reducing their side effects, the investigation...

Abstract: Helicobacter pylori (H. pylori) is a major human pathogen associated with significant morbidity and mortality. However, after decades of efforts, treatment of H. pylori remains a challenge for physicians, as there is no universally effective regimen. Due to the rising prevalence of antimicrobial resistance, mainly to clarithromycin, efficacy of standard triple therapies has declined to unacceptably low levels in most parts of the world. Novel regimens, specifically experimented to improve the therapeutic outcome...

Abstract: Inflammatory bowel diseases (IBDs), namely Crohn's disease and ulcerative colitis, are lifelong chronic disorders arising from interactions among genetic, immunological and environmental factors. Although the origin of IBDs is closely linked to immune response alterations, which governs most medical decision-making, recent findings suggest that gut microbiota may be involved in IBD pathogenesis. Epidemiologic evidence and several studies have shown that a dysregulation of gut microbiota (i.e., dysbiosis) may...
