Humans have an important association with their intestinal microbial flora. The microbial flora helps to shape the mammalian innate immune system, absorbs nutrients, and plays an intricate role on intestinal development. Microbes and mammals communicate with each other through an array of hormone and hormonelike chemical compounds. These "signals," however, are hijacked by bacterial pathogens, ...
introduction: irritable bowel syndrome (ibs) is a common gastrointestinal disorder in children that may lead to anxiety, frequent physician visits and school absenteeism. the aim of this study is to reviewe effects of probiotic for irritable bowel syndrome. materials and methods: this study review articles about probiotic for irritable bowel syndrome in pubmed and google scholar. results: m...
BACKGROUND The intestinal microbiota plays a critical role in the pathophysiology of pouchitis, a major complication after ileal pouch anal anastomosis in patients with ulcerative colitis. Recently, controlled trials have demonstrated that probiotics are effective in maintenance of remission in pouchitis patients. However, the mechanism by which therapy with probiotics works remains elusive. Th...
BACKGROUND Intestinal ischemia-reperfusion (I/R) plays an important role in critical illnesses. Gut flora participate in the pathogenesis of the injury. This study is aimed at unraveling colonic microbiota alteration pattern and identifying specific bacterial species that differ significantly as well as observing colonic epithelium change in the same injury model during the reperfusion time cou...
Aims In recent years, the role of gut flora in inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn ́s Disease (CD) has become focus of intense research. The working hypothesis is that an altered microbiota causes mucosal inflammation in a genetically susceptible individual. Understanding the microbiota ́s role in the pathogenesis of the disease is essential for new IBD ...
The type and distribution of bacteria in the jejunal juice of patients with a variety of gastrointestinal conditions that might affect the small intestinal flora were examined. Bacterial colonization of the jejunum defined, in this context, as the occurrence of a bile salttolerant flora consisting of both aerobic and anaerobic bacteria qualitatively resembling that of faeces, was observed only ...
INTRODUCTION Bowel-associated dermatosis-arthritis syndrome is rare systemic diseases characterized by a prodrome of fever, chills, and influenza-like symptoms with subsequent skin eruptions, myalgias, and polyarthralgias. It is reported to be occurred in Intestinal bypass surgery and inflammatory bowel disease. CASE DESCRIPTION Herein, we described a 29-years-old man with Bowel-associated de...
the aim of this study was to assess the effects of nucleotide on intestinal microbiota of striped catfish, pangasianodon hypophthalmus . different levels of the nt (0, 0.25. 0.5, 0.75 and 1 % weight per weight, ww -1 ) were added to basal diet and then randomly allocated to triplicate groups of fish with average initial weight (1.52±0.11 g) for 10 weeks. at the end of the experiment, at least 1...
Escherichia coli K-12 Hfr and F- strains were successively implanted in axenic chicks. Conjugation with exchanges of chromosomal genes occurred with high frequencies in the gut of the chicks and could continue as long as fertile strains coexisted in this environment. Almost all of the expected recombinant types were recovered in the feces under these experimental conditions. Furthermore, these ...
The intestine is a highly vascularized organ, and the splanchnic microcirculation is now appreciated to play a key role in immune and inflammatory responses in the gut. Emerging evidence demonstrates that the enteric flora not only exerts an important effect on innate immunity and the mucosal immune system, but will also affect inflammatory and angiogenic mechanisms involving the gut microcircu...
