Emerging data indicate that humans enjoy health through a productive collaboration with their colonizing flora, the majority of whom reside in the colon. This minireview provides a perspective on recent data and the exciting scientific challenges ahead.
Eighteen patients with urinary tract infection were treated with cephalexin orally. Absorption was variable, between 29 and 89% of the total daily dose being excreted in the urine in 24 hours. A significant number of patients became faecal carriers of Pseudomonas aeruginosa compared with a control group who received no antibiotics. Four of the cephalexin-treated patients acquired a strain of Ps...
alzheimer’s disease (ad) is a neurodegenerative disease that is the most common type of dementia.ad includes 60_80% of dementia and most people with ad have more than 65 years old.ad causes losing neuronal activity by abnormal proteins. plaques of beta-amyloid and tangles of “tau” protein can lead to ad. recently evidence has found that ad may come from outside of central nervous system (cns) a...
The human gut is the natural habitat for a large and dynamic bacterial community, but a substantial part of these bacterial populations are still to be described. However, the relevance and effect of resident bacteria on a host's physiology and pathology has been well documented. Major functions of the gut microflora include metabolic activities that result in salvage of energy and absorbable n...
Regulation of intestinal inflammation by microbiota following allogeneic bone marrow transplantation
Despite a growing understanding of the link between intestinal inflammation and resident gut microbes, longitudinal studies of human flora before initial onset of intestinal inflammation have not been reported. Here, we demonstrate in murine and human recipients of allogeneic bone marrow transplantation (BMT) that intestinal inflammation secondary to graft-versus-host disease (GVHD) is associat...
1. ["'C]Cyclamate was not metabolized when incubated with the liver, spleen, kidney or blood of rats or rabbits kept on a cyclamate-containing diet, and that had become converters of cyclamate into cyclohexylamine. 2. ["'C]Cyclamate was converted into cyclohexylamine when incubated under anaerobic conditions with the contents of the caecum, colon or rectum or with the faeces of cyclamate-pretre...

The intestinal microflora is a positive health asset that crucially influences the normal structural and functional development of the mucosal immune system. Mucosal immune responses to resident intestinal microflora require precise control and an immunosensory capacity for distinguishing commensal from pathogenic bacteria. In genetically susceptible individuals, some components of the flora ca...
Probiotic ingestion can be recommended as a preventative approach to maintaining the balance of the intestinal microflora and thereby enhance 'well-being'. Research into the use of probiotic intervention in specific illnesses and disorders has identified certain patient populations that may benefit from the approach. Undoubtedly, probiotics will vary in their efficacy and it may not be the case...
