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: PURPOSE OF REVIEW: The aim of this review was to evaluate recently published review articles which examine the use of nutritional supplements to prevent preterm birth (PTB) by modifying vaginal bacteria.RECENT FINDINGS: Probiotics, vitamin D and vitamin C were all identified as nutritional supplements that have the potential to alter bacterial flora and consequently reduce PTB and treat or prevent genital infections. Evidence shows that probiotics may reduce the incidence of PTB as well as being effective at...

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: A well-documented health benefit of probiotics is their ability to reduce the incidence of diarrhea in young, malnourished children in the developing countries. This study was undertaken to determine whether peanut butter, a nutritious, low-moisture food could be a carrier for probiotics by observing the survivability of selected probiotic mixtures in peanut butter under different storage conditions. Commercial probiotic mixtures (B, U, N and S) comprising of multiple strains of Lactobacillus, Bifidobacterium,...

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: 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 effects of dietary supplementation of probiotics on digestive enzymes activities, intestinal morphology and microbiota in juvenile paddlefish (Polyodon spathula) were studied. A total of 400 fish were reared in two cages and fed with a basal diet (control group, CG) or diet supplemented with commercial probiotics (treatment group, TG) for 80 days. Enzymes activities analysis indicated that protease and α-amylase activities increased (P < 0.01 or P < 0.05) in TG. Light microscopy observation...

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...

Abstract: Bifidobacterium, one of the major intestinal microflora components, shows anti-influenza virus (IFV) potential as a probiotic, partly through enhancement of innate immunity from modulation of the intestinal immune system. We isolated Bifidobacterium longum MM-2 (MM-2), a very safe bacterium in humans, from healthy humans. Here, we show the protective effect of MM-2 against IFV infection in a murine model. In mice that had been intranasally inoculated with IFV, consecutive oral administration of MM-2 improved...

Abstract: The incidence of obesity and its related conditions, including non-alcoholic fatty liver disease (NAFLD), has dramatically increased in all age groups worldwide. Given the health consequences of these conditions, and the subsequent economic burden on healthcare systems, their prevention and treatment have become major priorities. Because standard dietary and lifestyle changes and pathogenically-oriented therapies (e.g., antioxidants, oral hypoglycemic agents, and lipid-lowering agents) often fail due to poor...

Abstract: The potential for the positive manipulation of the gut microbiome through the introduction of beneficial microbes, as also known as probiotics, is currently an active area of investigation. The FAO/WHO define probiotics as live microorganisms that confer a health benefit to the host when administered in adequate amounts. However, dead bacteria and bacterial molecular components may also exhibit probiotic properties. The results of clinical studies have demonstrated the clinical potential of probiotics in many...

Abstract: Ulcerative colitis (UC) is a leading form of inflammatory bowel disease that involves chronic relapsing or progressive inflammation. As a significant proportion of UC patients treated with conventional therapies do not achieve remission, there is a pressing need for the development of more effective therapies. The human gut contains a large, diverse, and dynamic population of microorganisms, collectively referred to as the enteric microbiota. There is a symbiotic relationship between the human host and the enteric...

Abstract: The growing number of bacterial pathogens that are resistant to numerous antibiotics is a cause for concern around the globe. There have been no new broad-spectrum antibiotics developed in the last 40 years, and the drugs we have currently are quickly becoming ineffective. In this article, we explore a range of therapeutic strategies that could be employed in conjunction with antibiotics, and may help to prolong the lifespan of these life-saving drugs. Discussed topics include anti-resistance drugs, which are...

Abstract: Underlying pathophysiological mechanisms of irritable bowel syndrome (IBS), a common disorder characterized by abdominal pain associated to a change in stool consistency or frequency, include low-grade inflammation and intestinal microbiota changes. Few and disappointing data are available for prebiotics. A few controlled trials (RCTs) of probiotics are instead available with favourable effects, although most are limited by suboptimal design and small sample size. A recent report from the Rome foundation group...

Abstract: Inflammatory bowel diseases (IBD) are chronic inflammatory conditions, characterised by remissions and relapses episodes, whose main manifestations are ulcerative colitis and Crohn's disease. Ulcerative colitis (UC), one of the main forms of IBD, has as standard treatment the use of corticosteroids and anti-inflammatory drugs. The use of antibiotics has been also reported, but the possible adverse effects, such as disturbance of the indigenous microbiota or resistance induction, should be taken into consideration,...

Abstract: Lactobacilli and bifidobacteria are considered one of the permanent genera of the physiological human intestinal microbiota and represent an enormous pool of potential probiotic candidates. Approximately 450 isolates of presumptive Lactobacillus or Bifidobacterium strains were obtained from bioptic samples of colonic and ileal mucosa from 15 adolescents aged 12 to 18 years. On the basis of randomly amplified polymorphic DNA (RAPD)-PCR analysis, 20 strains were selected for further taxonomic classification and...
