In previous years, it has been shown that human milk is a potential source of bacteria for the infant gut. The results of this work confirm the presence of the same specific bacterial strains of Bifidobacterium, Lactobacillus, and Staphylococcus in breast milk and infant fecal samples. The identity of bacteria isolated from breast milk and infant feces from 20 mother-infant pairs was investigat...
Probiotics play an important role in the maintenance of the gastrointestinal barrier. In addition to direct effects on mucosal integrity, the interaction with the intestinal mucosa may have an active immunoregulatory effect. In the present work, we exposed HT29 intestinal epithelial cells to two Bifidobacterium species to determine their effect on gene expression profile, enterocyte monolayer i...
In order to clarify the distribution of bifidobacterial species in the human intestinal tract, a 16S rRNA-gene-targeted species-specific PCR technique was developed and used with DNAs extracted from fecal samples obtained from 48 healthy adults and 27 breast-fed infants. To cover all of the bifidobacterial species that have been isolated from and identified in the human intestinal tract, specie...
Biochemical characterization of the purified bile salt hydrolase (BSH) from Bifidobacterium bifidum ATCC 11863 revealed some distinct characteristics not observed in other species of Bifidobacterium. The bsh gene was cloned from B. bifidum, and the DNA flanking the bsh gene was sequenced. Comparison of the deduced amino acid sequence of the cloned gene with previously known sequences revealed h...
The aim of this study was to investigate the influence of a topically administered hygienic preparation containing a 3% ethanolic extract of Brazilian green propolis (EEP-B) on oral microflora spectrum changes in a group of patients who underwent common oral surgery procedures. Two gel samples were compared: the tested gel containing an active ingredient, that is, a 3% EEP-B (gel GA), and a pla...
Bifidobacterium and Lactobacillus can beneficially affect the host by producing acetic acid and lactic acid, which lower pH and thereby inhibit the growth of pathogens or allow the probiotic bacteria to compete with pathogens for epithelial adhesion sites and nutrients. The transmural migration of enteric organisms into the peritoneal cavity can cause peritonitis in peritoneal dialysis (PD) pat...
AIM : Although numerous animal studies suggest that probiotic therapy has beneficial effects in various liver diseases, the evidence for beneficial effects in human liver disease is controversial. This study was carried out to investigate the efficacy of probiotic therapy in alleviating small intestinal bacterial overgrowth (SIBO) and permeability in chronic liver disease. METHODS Fifty-three...
BACKGROUND/OBJECTIVES Feeding in infancy is the most significant determinant of the intestinal microbiota in early life. The aim of this study was to determine the gut microbiota of Korean infants and compare the microbiota obtained between breast-fed and formula-fed Korean infants. SUBJECTS/METHODS We analyzed the microbial communities in fecal samples collected from twenty 4-week old Korean...
