Variation in the antibiotic producing bacterial flora of the human intestinal tract.
Various studies on the antagonistic activity of intestinal organisms have compared the antibacterial spectra of cultures isolated from large numbers of people (Halbert, 1948a; Gardner, 1950; Blackford et al., 1951; Cook et al., 1953). Little emphasis, however, has been placed on variation in antibiotic production by the organisms of a given person over a period of time. Halbert (1948b) reports ...
متن کاملDiversity of the human intestinal microbial flora.
The human endogenous intestinal microflora is an essential "organ" in providing nourishment, regulating epithelial development, and instructing innate immunity; yet, surprisingly, basic features remain poorly described. We examined 13,355 prokaryotic ribosomal RNA gene sequences from multiple colonic mucosal sites and feces of healthy subjects to improve our understanding of gut microbial diver...
متن کاملDegradation of human intestinal glycosphingolipids by extracellular glycosidases from mucin-degrading bacteria of the human fecal flora.
Certain normal strains of human fecal bacteria are unique in producing extracellular glycosidases that degrade the oligosaccharide chains of gut mucin glycoproteins. We have studied the action of such glycosidases partially purified from the cell-free supernates of five of these strains on intestinal glycosphingolipids isolated from human meconium. The glycolipids were sialosyl-lactosylceramide...
متن کاملIsolation of Human Intestinal Bacteria Capable of Producing the Bioactive Metabolite Isourolithin A from Ellagic Acid
Urolithins are intestinal microbial metabolites produced from ellagitannin- and ellagic acid-containing foods such as walnuts, strawberries, and pomegranates. These metabolites, better absorbed than their precursors, can contribute significantly to the beneficial properties attributed to the polyphenols ellagitannins and ellagic acid (EA). However, both the ability of producing the final metabo...
متن کاملAntibiotics suppress Cyp3a in the mouse liver by reducing lithocholic acid-producing intestinal flora.
We previously demonstrated that ciprofloxacin (CPX), a new quinolone antibiotic, suppresses Cyp3a in the mouse liver by reducing the hepatic level of lithocholic acid (LCA) produced by intestinal flora. The present study investigated the possibility that other antibiotics with antibacterial activity against LCA-producing bacteria also cause a decrease in the LCA level in the liver, leading to r...
