INTRODUCTION Lactulose is a prebiotic with bifidogenic and urea reduction effects. It can improve Bifidobacteria and Lactobacilli counts in healthy humans and it may possibly have similar effects in chronic kidney disease (CKD) patients. OBJECTIVES To investigate the effect of lactulose on fecal microflora of patients with CKD. PATIENTS AND METHODS Thirty-two patients with stages 3 and 4 of...
Adhesion of 19 Bifidobacterium strains to native maize, potato, oat, and barley starch granules was examined to investigate links between adhesion and substrate utilization and to determine if adhesion to starch could be exploited in probiotic food technologies. Starch adhesion was not characteristic of all the bifidobacteria tested. Adherent bacteria bound similarly to the different types of s...
Fructooligosaccharides (FOS) can selectively stimulate the growth of bifidobacteria. Here, we investigated the effect of maternal FOS ingestion on maternal and neonatal gut bifidobacteria. In a randomized, double-blind, placebo-controlled study, we administered 8 g/day of FOS or sucrose to 84 women from the 26th week of gestation to one month after delivery. The bifidobacteria count was detecte...
Strategies to manipulate the intestinal microbiota have been considered to promote immune health. The aim of the present study was to examine whether fructo-oligosaccharide, a typical prebiotic, could suppress antigen-specific skin inflammation by favourably changing the population of intestinal microbiota. Female BALB/c mice were fed a synthetic diet with or without fructo-oligosaccharide supp...
The bifidobacterial and lactobacillus populations of fecal samples collected from 10 human subjects were studied. The numbers of bifidobacteria were similar in the fecal samples of all of the subjects, but lactobacillus numbers varied, even between samples collected from the same individual. Analysis of the composition of the bacterial populations by ribotyping and pulsed-field gel electrophore...
Agave fructans are complex and highly branched molecules, which cannot be digested in the upper gastrointestinal tract. As a result, when they reach the large intestine, they serve as fermentative substrates for bacterial growth. Previous reports have shown that fructans of the inulin-type, through both in vitro and in vivo assessments, are effective prebiotics, increasing the content of bifido...
Background: Recently, using probiotics for preventing and treating the immune system diseases via increasing the absorption of protective factors has attracted the attention of researchers. The aim of the present study was to evaluate the effect of probiotic bacteria, Lactobacillus plantarum 299v and Bifidobacteria B94, on serum Fe +2 and vitamin D3 levels following ethidium bromide - ...
Several studies have reported that the Intestinal microbiota of IBS patients is altered and differs from healthy people. Such condition of dysbiosis, associated with physical or psychological stress, may increase the intestinal barrier permeability, hypersensitize the afferent fibers of the enteric nervous system, and thus contributing to the clinical manifestations of the syndrome. Bifidobacte...
In addition to a nutritive role, human milk also guides the development of a protective intestinal microbiota in the infant. Human milk possesses an overabundance of complex oligosaccharides that are indigestible by the infant yet are consumed by microbial populations in the developing intestine. These oligosaccharides are believed to facilitate enrichment of a healthy infant gastrointestinal m...
Strains of the genus Bifidobacterium are frequently used as probiotics, for which the absence of acquired antimicrobial resistance has become an important safety criterion. This clarifies the need for antibiotic susceptibility data for bifidobacteria. Based on a recently published standard for antimicrobial susceptibility testing of bifidobacteria with broth microdilution method, the range of s...
