Abstract: Although probiotics are known to enhance the host immune response, their roles in modulating immunosenescence, resisting infection, and improving redox homeostasis during aging remain unclear. Therefore, the present study was devised in aging mice to assess the antiimmunosenescence potential from the consumption of milk that is fermented with probiotic Lactobacillus fermentum MTCC 5898 (LF). We hypothesized that probiotic supplementation would boost immunity, improve antioxidant capacity, and resist severity...

Abstract: The aim of this study was to characterize the probiotic characteristics of L. fermentum strains isolated from Tulum cheese. Seven L. fermentum strains were selected among the isolated and identified lactobacillus strains due to their abundance. When the gastric condition was considered, L. fermentum LP3 and LP4 were able to tolerate pH 2.5 and 1% bile salt. All L. fermentum strains had similar enzymatic activity and antibiotic resistance pattern but the highest antagonistic effect was detected within LP3, LP4...

Abstract: Kefir is a fermented dairy beverage produced by the actions of the microflora encased in the "kefir grain" on the carbohydrates in the milk. Containing many bacterial species already known for their probiotic properties, it has long been popular in Eastern Europe for its purported health benefits, where it is routinely administered to patients in hospitals and recommended for infants and the infirm. It is beginning to gain a foothold in the USA as a healthy probiotic beverage, mostly as an artisanal beverage,...

Abstract: Altered bowel flora is currently thought to play a role in a variety of disease conditions, and the use of Bifidobacterium spp. and Lactobacillus spp. as probiotics has been demonstrated to be health-promoting, even if the success of their administration depends on the applied bacterial strain(s) and the targeted disease. In the last few decades, specific probiotics have been shown to be effective in the treatment or the prevention of acute viral gastroenteritis, pediatric post-antibiotic-associated diarrhea,...

Abstract: Background: Probiotics increase beneficial microbiota and improve chronic conditions, such as atopic diseases, irritable bowel disease, and obesity. However, because there are so many probiotics, it is unknown which probiotics might have more of an effect on intestinal microbiota. Objective: To understand how two different types of probiotics influence human intestinal microbiota, human fecal microbiota were analyzed after ingestion of each of the probiotics. Methods: Ten outpatients were enrolled. Study A:...

Abstract: As studies uncover the breadth of microbes associated with human life, opportunities will emerge to manipulate and augment their functions in ways that improve health and longevity. From involvement in the complexities of reproduction and fetal/infant development, to delaying the onset of disease, and indeed countering many maladies, microbes offer hope for human well-being. Evidence is emerging to suggest that microbes may play a beneficial role in body sites traditionally viewed as being sterile. Although...

Abstract: The viability of bacteria during industrial processing is an essential quality criterion for bacterial preparations, such as probiotics and starter cultures. Therefore, producing stable microbial cultures during proliferation is of great interest. A strong correlation between the culture medium and cellular morphology was observed for the lactic acid bacterium Lactobacillus acidophilus NCFM, which is commonly used in the dairy industry as a probiotic supplement and as a starter culture. The cell shapes ranged...

Abstract: While the role of microflora is well established in the development of inflammatory bowel disease; data is still emerging regarding irritable bowel syndrome as the knowledge on brain---gut interaction grows. For both patient groups multiple efficacious treatments exist, but there are still unmet needs as long term disease control remains an issue. Given the importance of the microbiome on the development of the immune system and the interaction between the microbiome and the host organism, this 'route' is being...

Authors: Barouei J1, Moussavi M1, Hodgson DM2.

Abstract: Alterations in immune responses and intestinal secretory state are among features commonly observed in the maternal separation (MS) rat model of Irritable Bowel Syndrome. This study examined whether perinatal maternal introduction of probiotics influences plasma immune markers and ileal mucin-2 (MUC2) gene expression in rat offspring exposed to neonatal maternal separation (MS, 3 h/day, postnatal days (PND) 2-14) and/or subsequently to acute restraint stress in adulthood (AS, 30 min/day, PND 83-85). Data analysis...

Abstract: The microbiota has been shown to have the potential to affect appetite and blood lipids positively in animal studies. We investigated if four weeks supplementation with Lactobacillus paracasei subsp. paracasei L. casei W8® (L. casei W8) had an effect on subjective appetite sensation, ad libitum energy intake, glucagon-like peptide 1 (GLP- 1), glucose and insulin response in humans. Secondarily, we explored potential effects on blood lipids, fatty acids and stearoyl-CoA desaturase-1 (SCD1) activity in humans...

Abstract: BACKGROUND: Recurrence is a frequent complaint of patients with vulvovaginal candidiasis (VVC). Although the pathogenesis of VVC remains a controversial issue, disruption of the balance between the vaginal microbiota may facilitate overgrowth by Candida. Some probiotic bacterial strains can suppress Candida albicans; Lactobacillus plantarum P17630 is able to attach to vaginal epithelial cells and significantly reduce the adhesion of C. albicans.OBJECTIVE: To evaluate the effect of the application of Lactobacillus...

Abstract: Several risk factors for the development of schizophrenia can be linked through a common pathway in the intestinal tract. It is now increasingly recognized that bidirectional communication exists between the brain and the gut that uses neural, hormonal, and immunological routes. An increased incidence of gastrointestinal (GI) barrier dysfunction, food antigen sensitivity, inflammation, and the metabolic syndrome is seen in schizophrenia. These findings may be influenced by the composition of the gut microbiota....

Abstract: The gastrointestinal microbiota is extremely important for human and animal health. Investigations into the composition of the microbiota and its therapeutic modification have received increasing interest in human and veterinary medicine. Probiotics are a way of modifying the microbiota and have been tested to prevent and treat diseases. Probiotics are proposed to exert their beneficial effects through various pathways. Production of antimicrobial compounds targeting intestinal pathogens, general immune stimulation,...

Abstract: Probiotics are live microbial food supplements that are beneficial to the host health when administered in adequate amounts. Probiotics do have an exciting concept in digestive functions, but these live microbes have wider applicability as evidenced by gut-brain-skin axis theory given 80years back. However, the details regarding use of probiotics for dermatological indications ranging from atopic dermatitis to acne and sexually transmitted infections is dispersed in the literature, herein we have tried to focus...

Abstract: Asthma and allergic diseases have become one of the epidemics of the 21st century in developed countries. Much of the success of other areas of Medicine, such as infectious diseases, lies on preventive measures. Thus, much effort is also being placed lately in the prevention of asthma and allergy. This manuscript reviews the current evidence, divided in four areas of activity. Interventions modifying environmental exposure to allergens have provided inconsistent results, with multifaceted interventions being...

Abstract: The concept of prebiotic edible films as effective vehicles for encapsulating probiotic living cells is presented. Four soluble fibres (inulin, polydextrose, glucose-oligosaccharides and wheat dextrin) were selected as prebiotic co-components of gelatine based matrices plasticised with glycerol and used for the immobilisation of Lactobacillusrhamnosus GG. The addition of prebiotics was associated with a more compact and uniform film structure, with no detectable interspaces or micropores; probiotic inclusion...

Abstract: Important advances during the last decade have been made in understanding the complex etiopathogenesis of Crohn's disease (CD). While many gaps in our knowledge still exist, it has been suggested that the etiology of CD is multifactorial including genetic, environmental and infectious factors. The most widely accepted theory states that CD is caused by an aggressive immune response to infectious agents in genetically predisposed individuals. The rise of genome-wide association studies allowed the identification...

Abstract: Bacteria use cell-to-cell communication systems based on chemical signal molecules to coordinate their behavior within the population. These quorum sensing systems are potential targets for antivirulence therapies, because many bacterial pathogens control the expression of virulence factors via quorum sensing networks. Since biofilm maturation is also usually influenced by quorum sensing, quenching these systems may contribute to combat biofouling. One possibility to interfere with quorum sensing is signal inactivation...
