• Abstract

  Ulcerative colitis (UC) is an intestinal disease manifesting in the colon mucosa as ulcerations, of varying intensity and extension which are detected in colonoscopy examinations. It is incurable, of unknown cause and associated with several factors, including disequilibrium in species composition of the microbiome (dysbiosis). Gut dysbiosis in UC implies not only in the reduction of micr…

  Modulation of gut microbiome of ulcerative colitis patients: a ramdomized, double blind, controled study, AP.R

• Abstract

  Background. Dysbiosis is linked to the cause of several human diseases, many of which having an immunity related component. This work investigated whether mice genetically selected for low or high antibody production display differences in intestinal bacterial communities, and consisted in the comparison of fecal 16SV6-V8 rDNA PCR amplicons resolved by temperature gradient gel electrophor…

• Abstract

  Inflammatory bowel diseases (IBD) are manifested as mucosal lesions along the intestinal tract, with symptoms ranging from a simple discomfort to serious alterations affecting the organ's function. Two main IBD clinical variants are known: ulcerative colitis (UC) and Crohn's disease (CD), which are distinguished by several particular features, including the extent of intestinal commitment…

• Abstract

  Crohn's disease is a pathology characterized by the upsurge of lesions of varying severity which may affect the entire length of the intestinal tract, eventually leading to intestinal fistulas and/or obstruction. These manifestations are supported by an exacerbated immune response against antigens of the intestinal microbiota triggered by a defective immunologic system in these patients. …

  Qualitative assessment of the facultative and aerobe gram negative bacteria of the intestinal microbiota of Crohn’s disease patients, BP.IC

• Abstract

  Inflammatory bowel diseases (IBD) are clinical manifestations marked by the upsurge of lesions along the gastrointestinal tract which are associated with chronic inflammatory processes. It is assumed that these processes result from the inability of the immune system in properly recognizing bacterial antigens of the resident microbiota. On the other hand, some authors argue that these re…

  Assessment of the invasive ability expressed by Escherichia coli strains isolated from the lumen and from different intestinal mucosal sites of inflammatory bowel diseases patients, BP.IC

• Abstract

  Enteroaggregative Escherichia coli (EAEC) have this designation because of their typical adhesion pattern (aggregative) shown in tests performed with epithelial cells. This class of bacteria is very heterogeneous in its properties, including innocuous and pathogenic isolates. The later have been associated with enteritis as well as extra intestinal infections. In recent observations we no…
