BACKGROUND Changes in the human microbiome have been suggested as a risk factor for a number of lifestyle-related disorders, such as atopic diseases, possibly through a modifying influence on immune maturation in infancy. OBJECTIVES We aimed to explore the association between neonatal fecal flora and the development of atopic disorders until age 6 years, hypothesizing that the diversity of th...

Our intestines are habitat for trillions of microorganisms such as bacteria, viruses and eukaryotes, known as microbiota. They are indispensable for our well-being due to their metabolic activities. Microbiota digests complex plant polysaccharides, which are normally unprocessed by humans; as well it retrieves other essential nutrients. It is well established that microbiota is crucial for prop...

From numerous studies during the last years it became evident that bacteria and bacterial constituents play a decisive role both in the maintenance of intestinal immune homeostasis as well as in the development and perpetuation of chronic intestinal inflammation. In this review we focus on the role of bacterial DNA which is a potent immunomodulatory component of the bacterial flora. Bacterial D...

The normal bacterial flora contains antibiotic resistance genes to various degrees, even in individuals with no history of exposure to commercially prepared antibiotics. Several factors seem to increase the number of antibiotic-resistant bacteria in feces. One important factor is the exposure of the intestinal flora to antibacterial drugs. Antibiotics used as feed additives seem to play an impo...

Klite, P. D. (Middle America Research Unit, Balboa Heights, Canal Zone). Intestinal bacterial flora and transit time of three neotropical bat species. J. Bacteriol. 90:375-379. 1965.-Quantitative studies on the intestinal bacterial flora of three neotropical bat species revealed the following average bacterial populations: Molossus major, 10(4.8) bacteria per intestinal contents; Carollia persp...

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...

The intestinal bacteria, Eubacterium sp. and Bifidobacterium sp., participate in the metabolism of active kampo-ingredients, glycyrrhizin (GL), sennoside (SEN) and baicalin (BL). Since antibiotics and bacterial preparations, Bifidobacterium longum (LAC-B), Clostridium butyricum (MIYA-BM), and Streptococcus faecalis (BIOFERMIN), affect the bacterial population in intestinal bacterial flora, meta...

Mammals coexist in an overall symbiotic relationship with a complex array of commensal bacterial flora that colonizes the gastrointestinal tract. These intestinal bacteria interface with cells of the mucosal immune system, including DCs. Here we discuss mechanisms of interaction between intestinal bacteria and DCs and the role of localized gastrointestinal immune responses.

Metabolic acidosis in a 3-year-old child with short bowel syndrome led to the discovery of massive D-lactic aciduria. After normalisation of the intestinal bacterial flora, D-lactate disappeared together with the acidosis. Dysbacteriosis with excessive production of D-lactate by intestinal bacteria (unidentified) and subsequent absorption explains this unusual cause of metabolic acidosis.
