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: 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: 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...

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...
